This document governs the Ambetter prescription drug formulary (January 1, 2026) including coverage tiers, prior authorization, step therapy, quantity and age limits, specialty drug routing, and limits for opioid prescriptions; it affects providers and members served under the Ambetter/Centene prescription drug benefit.
No material clinical or coverage changes in this revision.
Formulary Coverage Criteria
Formulary tier coverage
Formulary coverage is tiered and may include limits or requirements; coverage and prior authorization rules apply as described.
Tier descriptions and specialty fill requirements provided.
Prior Authorization — Non-Formulary Drugs
Non-formulary drugs require prior authorization when requested as exceptions.
Denial notices will explain reasons or identify missing information.
Opioid limits (new starts)
Opioid prescribing for new starts is limited as specified.
Limit applies cumulatively to all opioid medications listed.
Formulary restrictions (per-product)
Coverage and restrictions are specified per listed product and include one or more of the following conditions applied:
See individual product lines for exact QL/PA/ST/SP and new-start language.
Covered with criteria
Products listed with a Tier and QL are covered subject to the specified quantity limits and any PA/SP requirements.
Individual line items define the exact QL, PA, SP and any age limits (AL).
Formulary tier and utilization management
Coverage is tier-based with utilization management controls; specific coverage is indicated by Tier = X and modifiers such as QL, PA, SP, and AL.
Providers must follow per-product modifiers when submitting claims or PA requests.
Formulary coverage indicators
Coverage and utilization controls are indicated by tier, quantity limits (QL), prior authorization (PA) and specialty pharmacy (SP) flags for listed drugs.
No additional clinical criteria are listed in this excerpt; PA indicates further review is required.
Formulary coverage with conditions
Coverage and restrictions are listed by formulary entries — products are assigned tiers and may include QL and PA conditions.
PA flags indicate additional documentation/authorization required prior to coverage.
Age-limited topical immunomodulators
Age and authorization restrictions apply to topical immunomodulators and tacrolimus formulations.
Prescribers must confirm patient age and obtain PA where indicated prior to dispensing.
The Ambetter Formulary is a guide to covered brand and generic drugs but is not a complete list of covered medications. Not all dosage forms or strengths may be covered and coverage can depend on the member's specific benefit plan. Formulary entries use tier assignments (e.g., Tier 0–4) and may include utilization controls such as Quantity Limits (QL), Prior Authorization (PA), Step Therapy (ST), specialty routing (SP), and age limits (AL); coverage is conditional on meeting the listed tier and any modifiers shown for the product.
Within the excerpt there are no standalone sections that explicitly list broad programmatic exclusions; entries are presented as tiers with per-product flags (e.g., QL, PA, AL). The document therefore does not state blanket ‘excluded’ categories in this extract — instead, coverage limitations are expressed on a product-by-product basis.
The excerpt does not present explicit clinical exclusions beyond the utilization controls shown for individual products. Restrictions that appear are primarily quantity limits (QL), prior authorization (PA), and initial-therapy/new-start constraints rather than diagnostic or indication-based exclusions.
This formulary extract does not contain a dedicated list of drugs labeled as ‘Not Covered.’ Instead, it provides tier assignments and product-level limits (QL, PA, AL) that govern coverage; specific benefit designs may further restrict coverage as noted in the general formulary guidance.
Some antimalarial products are restricted to malaria treatment only. For example, atovaquone-proguanil is indicated as “Covered for malaria treatment only” with QL(12 EA per fill) and a Limit: 1 fill every 180 days (per retail and mail entries).
Reiterating the excerpt’s format: there are no explicit programmatic exclusions stated here. Coverage constraints are communicated by per-product tiering and utilization markers (e.g., QL, PA, AL) rather than general exclusion statements in this extract.
For pancreatic enzyme (pancrelipase) products listed (e.g., CREON, ZENPEP), the excerpt notes that Non‑FDA approved uses require Prior Authorization. Providers should therefore expect PA to be required when requesting coverage for indications or formulations not described on the product labeling.
There are no explicit statements in the provided excerpt that any drugs or uses are labeled as Not Medically Necessary. The extract conveys utilization controls (QL/PA/ST) but does not include NMN determinations in the shown lines.
Consistent with other segments of the extract, the document does not include discrete ‘Not Medically Necessary’ determinations within the shown lines. Coverage decisions appear to be managed by PA, QL, AL, and tier flags rather than explicit NMN entries in this excerpt.
As noted above, the excerpt contains no explicit NMN statements. Absent product-specific PA or QL flags, the listing indicates conditional coverage by tier and utilization controls rather than explicit denials for medical necessity in the extract.
Certain unitized formulations of pancreatic enzyme products (ZENPEP entries and similar unit listings) explicitly tie Non‑FDA approved uses to prior authorization requirements in the extract. Where the entry indicates non‑FDA use, a PA is required before coverage will be considered.

Provider Requirements & Denial Risks
Submit PA for non‑formulary drugs
Providers must complete and submit the Ambetter Prior Authorization form for non‑formulary drug requests; urgent requests will be answered within 24 hours and non‑urgent requests within 72 hours after all required information is received.
- Submit the completed Prior Authorization form to Ambetter.
- Expect response: urgent = 24 hours; non‑urgent = 72 hours (unless state law requires faster).
Obtain PA for specialty/biologic agents
Many biologic and specialty agents listed on the formulary (for example multiple ADALIMUMAB presentations, ACTEMRA, ENBREL) are annotated with 'PA' and require prior authorization before coverage will be provided.
- Obtain PA prior to dispensing for biologic/specialty products shown with 'PA'.
- Package/quantity limits (e.g., package(s) per 180 days) may be enforced with PA requests.
PA required for opioid entries
Opioid-containing products and many analgesic entries show PA or new‑start constraints; where 'PA' is indicated, providers must secure prior authorization before coverage.
- New opioid starts are limited to a 7‑day supply unless authorized (see new‑start limits).
- If a listed opioid shows 'PA' obtain prior authorization before dispensing.
Get PA when 'PA' flag or max‑fill shown
Products explicitly annotated with 'PA' (and any shown maximum‑fill language) require prior authorization before the payer will provide coverage for that item.
- Check the formulary line for 'PA' or 'SP; PA' and obtain PA prior to dispensing.
- Observe any max‑fill or per‑period limits when preparing PA documentation.
Request PA for listed high‑cost/specialty products
Selected high‑cost or specialty agents in the list (examples include enoxaparin presentations, NAYZILAM, VALTOCO, SPRAVATO) are flagged 'PA' — providers must request prior authorization for these products.
- Confirm PA requirement on the specific product line (e.g., enoxaparin strengths, NAYZILAM, SPRAVATO).
- Do not dispense expecting coverage without approved PA.
Obtain PA for items marked 'PA' or 'SP; PA'
Multiple drugs and drug groups are designated 'PA' or 'SP; PA' (specialty + prior authorization); providers must obtain the required prior authorization before dispensing those items.
- When an entry shows 'SP; PA' route the request to the specialty channel and obtain PA.
- Confirm PA is approved prior to patient administration or pharmacy claim submission.
Do not dispense without PA when 'PA' shown
Any formulary entry that shows 'PA' requires prior authorization from Ambetter before coverage — providers must secure approval prior to dispensing the medication.
- Verify the product line for a 'PA' marker and obtain authorization prior to supply.
- Claims submitted without required PA may be denied.
Obtain PA for products with 'PA' noted
Many formulary lines include 'PA' next to the drug/strength (e.g., asenapine maleate and other example entries); obtain prior authorization as indicated on the product line.
- Check the specific strength/packaging line for PA notation.
- Provide PA approval before submitting pharmacy claims for those strengths.
Use specialty channel and obtain PA for 'SP; PA' items
Specialty products annotated 'SP; PA' require both specialty routing and prior authorization (example: FUZEON listed as 'SP; PA').
- Submit PA and ensure specialty pharmacy fulfillment where 'SP; PA' is shown.
- Coordinate with the specialty network per Ambetter guidance before dispensing.
PA required for SOFOSBUVIR‑VELPATASVIR
SOFOSBUVIR‑VELPATASVIR tablets are listed with 'PA' — providers must request prior authorization for hepatitis C treatment with this agent.
- Include clinical documentation supporting the hepatitis C indication when submitting PA for SOFOSBUVIR‑VELPATASVIR.
- Do not assume coverage without approved PA.
Secure PA for specialty pulmonary hypertension drugs
Several pulmonary hypertension and specialty pulmonary agents (e.g., treprostinil, epoprostenol, TYVASO kits, sildenafil/tadalafil PH products) are annotated with 'PA' or 'SP; PA' — obtain prior authorization before dispensing.
- Submit PA and supporting clinical documentation for pulmonary hypertension agents marked 'PA' or 'SP; PA'.
- Products with 'SP' may require specialty fulfillment in addition to PA.
Request PA for listed topical/systemic products
Certain topical and systemic dermatologic products (for example halobetasol‑related entries, isotretinoin, tacrolimus) list 'PA' — providers must request prior authorization for those formulations when indicated.
- Verify product line for PA and age limits (e.g., isotretinoin: AL(At least 12 yrs old) and PA).
- Include patient age and indication in PA submission for topical immunomodulators and tacrolimus.
Obtain PA for topical agents with 'PA'
Some topical agents such as halobetasol formulations and others are annotated with 'PA' on the formulary — obtain prior authorization when the product line indicates PA.
- Confirm the exact formulation/strength line for the PA annotation before prescribing.
- Provide required documentation with the PA request (age, indication, previous therapy as applicable).
Follow step therapy where 'ST' applies
Step therapy (ST) may apply to some products; the formulary indicates that, in applicable cases, a specified alternative must be tried before Ambetter will cover the requested agent.
- If 'ST' appears on the product line follow the step requirement (trial of preferred alternative) before requesting PA for the subsequent agent.
- Document prior trials when submitting an authorization if step therapy is applicable.
Document trial of ibuprofen for ACTEMRA (ST)
Example: ACTEMRA SOLN notes 'Must try ibuprofen: ST' — providers must document a trial of ibuprofen before the step requirement is satisfied for ACTEMRA.
- Document prior trial of ibuprofen when requesting coverage for ACTEMRA SOLN as indicated by the 'ST' note.
- Include trial duration and response in the PA/step documentation.
Comply with starter‑pack and 'SP' constraints
Some products are labeled 'SP' or appear as starter packs (e.g., ELIQUIS starter pack), indicating restricted distribution or starter‑pack rules; follow the indicated channeling/pack constraints when prescribing.
- Route starter packs or SP‑designated products through the specialty/pharmacy channel noted by the formulary.
- Observe per‑period max fill language (e.g., 1 max fill per 180 days for starter packs) when dispensing.
Use tiering to guide preferred choices
Therapeutic class tiering and tier assignments imply preferred agents (tiers 1A/1B/2/3/4); though explicit step algorithms are not provided, use tiering to guide preferred prescribing.
- When no explicit 'ST' is shown, prefer lower‑tier agents consistent with benefit design.
- If a higher‑tier agent is requested, be prepared to document prior trials or obtain PA if required.
Tiering suggests preferred agents
Tier assignments imply preferred status (lower tiers preferred); providers should consider lower‑tier alternatives first though the excerpt does not list full step rules.
- Check the product's tier before prescribing; choose lower‑tier options when clinically appropriate.
- If prescribing higher‑tier drugs, expect potential PA or justification requirements.
Adhere to 'ST' when shown
Where a product line shows 'ST' (step therapy), such as for some antiparkinson agents, providers must follow the step requirement (trial of the specified alternative) prior to approval.
- Document the required prior therapy when submitting an authorization for agents marked 'ST'.
- Failure to document prior trial may lead to denial or request for additional information.
No explicit step algorithm in excerpt — follow tiers and PA
The excerpt does not provide a complete step‑therapy algorithm; when 'ST' is not specified, follow documented tier preference and PA processes.
- If no explicit step sequence is listed, rely on tier preference and be prepared to provide prior therapy documentation if PA is requested.
- Consult full policy or pharmacy helpdesk for complete step therapy rules if uncertain.
Step therapy details not specified here — verify with payer
No explicit step therapy sequencing text is included in this extract; providers must refer to product lines for any 'ST' flags and to the payer for full step policy details.
- When 'ST' is shown on a product line, include documentation of prior trial(s) with the PA or step submission.
- Contact Ambetter for the complete step‑therapy algorithm if needed.
Follow 'ST' for listed topical products
Step therapy applies to specified products in the extract (examples include clindamycin/tretinoin and multiple corticosteroid entries marked 'ST'); follow the step requirement where shown.
- Document prior use of required alternative agents when requesting authorization for 'ST'‑flagged topical products.
- Include age and prior treatment details as required.
Tiering implies preference; verify 'ST' where applicable
Tier assignments imply preferred agents but do not replace explicit step requirements; verify 'ST' flags on product lines when applicable.
- If a product is higher tier, expect PA or step documentation may be required.
- Confirm any 'ST' note on the exact formulation line before submitting PA.
Submit PA with required documentation; note 24/72‑hour turnarounds
Providers must complete the Prior Authorization form and submit necessary clinical information; urgent requests will be answered within 24 hours and non‑urgent within 72 hours once all information is received.
- Submit completed PA form with supporting clinical documentation to avoid delays.
- Expect disapproval notices to state reasons or identify missing material information if the request is incomplete.
Document prior fills and package/fill‑intervals for PA requests
Formulary entries show quantity limits and package/fill‑interval language (e.g., package(s) per 180 days) — providers should document fill history and relevant dispensing intervals when submitting PA.
- Include prior fill history and justification when requesting exceptions to package or per‑period limits.
- Reference the exact per‑period limits from the product line in the PA request.
Document justification when requesting >7‑day opioid supply
When requesting authorization for opioid prescriptions exceeding new‑start limits, prescribers should document clinical justification for longer supplies — new starts are limited to a 7‑day supply per the formulary.
- Document rationale and prior therapy when requesting PA for opioid supplies beyond the 7‑day new‑start limit.
- Be aware policy permits up to two 7‑day fills in any 28‑day period and up to 28 non‑consecutive days in 90 days (per thresholds).
Include clinical justification for PA requests that seek QL overrides
Many product entries pair PA or SP flags with quantity limits (QL); when PA/QL are shown, include clinical justification for the requested quantity and dose in the PA submission.
- Provide diagnosis, prior therapies, and rationale for requested quantity when submitting PA for QL‑restricted products.
- Ensure claims reflect the QL/PA annotations to avoid rejection.
Ensure claims reflect QL and PA on approved authorizations
Pharmacy claims must reflect the formulary's QL and PA indicators; providers should ensure claim submissions include authorization identifiers and match the approved quantity/intervals.
- Include the PA approval number on the claim and adhere to approved quantity limits.
- Claims with quantities exceeding QL or missing required PA may be denied.
Document patient age and indication for AL‑restricted drugs
When a product has an Age Limit (AL) shown (for example isotretinoin, XIFAXAN entries), providers must document the patient's age and indication in the PA or claim.
- Include patient age and the clinical indication in the PA request for AL‑restricted products.
- Verify member meets the AL before dispensing or submitting the claim.
Provide supporting clinical documentation for PA/QL requests
For PA or QL requests, providers must supply supporting clinical documentation that justifies the requested quantity or dose (for example prior treatment history or clinical rationale).
- Attach prior therapy records, relevant labs, and treatment rationale to the PA submission.
- Insufficient documentation may lead to disapproval or request for additional information.
Document fill‑intervals when requesting QL exceptions
Quantity limits and fill‑interval language are enforced (examples: 1 max fill per 90/180 days, QL per fill/period); providers should document dispensing intervals when requesting exceptions or PA.
- Cite prior fill dates and quantities when asking for exceptions to max‑fill rules.
- Use the formulary's stated per‑period limits in the PA justification.
Provide documentation for SP/PA injectable products
Specialty (SP) and PA flags on injectable or infusion products indicate restricted distribution and require supporting documentation with PA submissions and routing through specialty channels as indicated.
- When 'SP' appears, coordinate with the specialty pharmacy network and include necessary supporting documents with the PA.
- Some infusion/injectable products require both SP routing and PA prior to coverage.
Document age and quantity compliance for AL/QL products
Age and quantity limits are enforced for multiple products (examples: pimecrolimus AL(At least 2 yrs); tacrolimus OINT AL + PA); providers must document age and QL compliance in PA requests.
- Confirm patient meets AL before submitting PA or dispensing.
- Include age and prior treatment details in the PA when AL or QL is listed.
Expect specific reasons on PA denials
If a prior authorization request is disapproved, the disapproval notice will state specific reasons for the denial or identify missing material information required to complete the request.
- Review the notice to determine whether additional information can cure the denial.
- Submit missing material information promptly when identified.
Claims may be denied for specialty drugs without PA
Claims for specialty agents may be denied if PA is not obtained when indicated (many specialty biologics and injectable products show 'PA' or 'SP; PA').
- Obtain PA prior to dispensing specialty biologics to avoid claim denials.
- Verify specialty routing requirements and PA approval before patient administration.
QL exceedance can trigger denials
Exceeding a product's quantity limit (QL) can trigger denial or require a prior authorization; document prior therapy and justification when requesting quantities beyond the QL.
- Do not submit claims exceeding QL without an approved PA.
- Include relevant clinical rationale and prior use when seeking QL exceptions.
PA/QL/new‑start limits may trigger denials
Entries marked with PA and/or those that exceed quantity or new‑start limits (e.g., new starts limited to 7 days) may trigger denials or require additional review; obtain PA where indicated.
- For new‑start opioid fills beyond 7 days, submit PA with supporting justification.
- If PA is required and not obtained, expect the claim to be denied or returned for review.
Missing PA/SP or exceeding QL risks denial
Formulary flags 'PA', 'SP', and explicit QL or max‑fill per period are common denial triggers — missing required PA or exceeding limits may cause claim denial or noncoverage.
- Before dispensing, verify whether the product line shows 'PA' or 'SP' and obtain approvals.
- Confirm the dispensed quantity and fill interval conform to formulary limits to avoid denials.
Obtain PA for enoxaparin strengths showing 'PA'
Multiple enoxaparin presentations are annotated with 'PA' — providers should obtain prior authorization for the listed enoxaparin strengths to avoid coverage denial.
- Check the exact enoxaparin strength/format for a 'PA' notation and secure authorization before dispensing.
- Claims for enoxaparin may be denied if PA is not in place.
Secure PA for CNS/rescue agents flagged 'PA'
Several CNS/rescue medications (examples: NAYZILAM, VALTOCO, SPRAVATO) are flagged with 'PA' — dispensing without prior authorization risks claim denial.
- Verify PA is approved before dispensing NAYZILAM, VALTOCO, or SPRAVATO formulations that show 'PA'.
- Include quantity limit compliance and indication in the PA to reduce denial risk.
PA or SP; PA markers require prior authorization
Formulary entries that display 'PA' or 'SP; PA' indicate prior authorization or specialty prior authorization requirements; failure to obtain required authorization may lead to claim denial.
- When the product line shows 'PA' or 'SP; PA', do not assume coverage without documented authorization.
- Follow specialty routing and documentation procedures for SP; PA items.
QLs are enforceable — request PA for exceedance
Quantity limits shown on product lines (examples: QL(4 EA daily; 40 EA per fill), QL(3 EA daily)) are enforceable utilization limits — requests exceeding these limits require PA or may be denied.
- Review the product's QL before prescribing and document justification when seeking exceedance.
- Include prior dispensing records in PA to support requests above QL.
Missing PA/SP may lead to denials
If PA or specialty pharmacy requirements are not met for products that list 'PA' or 'SP; PA', requests may be denied — verify and obtain necessary approvals prior to dispensing.
- Confirm and document PA/SP requirements on the exact product line before filling.
- Denials for missing PA/SP can be appealed with supporting clinical information if appropriate.
Initial Therapy Limits & Guidance
Initial therapy limits
Initial prescribing restrictions noted in the formulary for certain product classes.
Applies to initial prescriptions unless Prior Authorization is obtained.
Initial therapy examples
Examples of initiation utilization constraints observed in the formulary.
This is an example of how initial QL and PA modifiers are applied in the formulary.
Serves as an example of tier + QL application for chronic therapy agents.
Topical steroid initial therapy guidance
Topical corticosteroid and related topical agents are tiered and include initial quantity limits.
Prescribers should follow listed QL and obtain PA when indicated for topical steroids.
Step Therapy Requirements
| Step therapy summary |
|---|
| Step therapy (ST) may require trying alternative drugs before coverage of certain agents; example: lisdexamfetamine dimesylate entries show ST noted alongside QL (e.g., QL(1 EA daily); ST) |
| Step therapy example |
|---|
| ACTEMRA SOLN entry references quantity limits per 28 days and notes 'Must try ibuprofen: ST' (step therapy requiring trial of ibuprofen prior to coverage) |
| Tier-implied step therapy |
|---|
| Formulary assigns drugs to tiers (examples include Tier = 1A, 1B, 3, 4). These tier assignments imply preference for lower-tier agents and may result in required trials of lower-tier alternatives, although explicit step sequences are not provided in the excerpt. |
| Starter pack and SP constraints |
|---|
| Some products appear as starter packs or carry an 'SP' (specialty) flag; e.g., ELIQUIS DVTIPE STARTER PACK and XARELTO STARTER PACK entries list fill limits (1 max fill per 180 days or per-year language) and SP designations, indicating restricted distribution or starter-pack constraints. |
| Tier assignments |
|---|
| Multiple entries show tier designations (examples: 1A, 1B, 3, 4). Tiering indicates formulary preference but the excerpt does not provide full step-therapy sequences tied to those tiers. |
| ST flagged entries |
|---|
| Some antiparkinson and related therapy entries include the 'ST' annotation (e.g., antiparkinson drug groups show QL values plus 'ST'), indicating step therapy may apply to these agents. |
| Explicit step-therapy steps present? |
|---|
| The excerpt contains tiering and 'ST' flags for select products but does not list explicit multi-step progression rules or full step-therapy algorithms for members/providers to follow. |
| Excerpt scope on step therapy |
|---|
| No explicit step therapy step-by-step instructions are shown in this formulary excerpt; entries are limited to tier, QL, PA, SP, and occasional 'ST' annotations. |
| Topical products with ST |
|---|
| Several topical formulations list 'ST' (step therapy) — examples include clindamycin phosphate‑tretinoin and multiple topical corticosteroid entries (corticosteroids/topical agents show ST on some lines), indicating step requirements apply to selected topical therapies. |
| Tier designations (examples) |
|---|
| Formulary examples show tier assignments such as Tier = 1B and Tier = 3 for multiple agents (topical and systemic); specific step-therapy sequences are not provided alongside these tier designations. |
Quantity Limit Examples and Enforcement
Specialty, Infusion & Fulfillment Notes
Route specialty‑tier drugs to participating specialty/hemophilia pharmacies
Some infusion/ specialty‑tier drugs must be fulfilled at participating specialty or hemophilia network pharmacies; providers should route such prescriptions accordingly.
- Use Ambetter's specialty/hemophilia network for fulfillment when the product is specialty‑tier.
- Check Ambetter pharmacy information for network participation.
Coordinate PA and specialty handling for injectable/infusion products
Injectable/infusion products marked 'PA' and 'SP' indicate restricted distribution or specialty handling; obtain PA and coordinate specialty fulfillment before administration.
- Coordinate PA approval with the specialty pharmacy and confirm handling/fulfillment requirements.
- Do not schedule infusion/administration until PA and specialty routing are confirmed.
