Coverage rules and general formulary guidance
General coverage rule per listed requirement flags
Covered when ALL of the following are met:
Administrative requirement flags include: (PA) prior authorization, (QL) quantity limits, (ST) step therapy, (M) maintenance/medical-necessity review, (AGE) age limits. See item-level Requirements & Limits for flags applicable to the specific product.
Some drugs in the formulary are designated as noncovered. For those items, members, their prescribing physician, or the dispensing pharmacy may request coverage by submitting a Drug Coverage Exception Form and providing documentation of medical necessity. Requests for noncovered drug coverage are considered on a case‑by‑case basis.
Within the provided extract there are no explicit exclusion lists shown that categorically remove specific drug classes or products from coverage; formulary entries instead show tier assignments and utilization flags (e.g., PA, QL, M, ST, AGE) that govern coverage conditions.
The source segments reviewed do not include any statements explicitly labeling products as not medically necessary. Coverage determinations in this extract are driven by tier assignments and administrative requirement flags rather than explicit 'not medically necessary' language.
Formulary entries, tiers, and flags (coding view)
| No codes listed |
| Tier 2 | Drug Tier = 2 (assigned to multiple entries such as Glipizide, Fluorouracil Cream in one line, etc.) |
| PA | Prior Authorization requirement flag |
| QL | Quantity Limit requirement flag |
| M | Requirement flag (document-specific) |
| ST | Step Therapy requirement flag |
| AGE | Age limit flag |
What providers must do (authorizations, documentation, step therapy)
Prior authorization required
Coverage of certain drugs requires prior authorization (PA) before the plan will pay. If a drug is marked with (PA) in the formulary, obtain PA prior to dispensing — otherwise the member may be held responsible for the drug's full retail cost and the claim may be denied.
- Examples: Repatha, Mounjaro, Trulicity, Soliqua and other products shown with (PA) in the formulary.
- Claims submitted without required PA are subject to denial or member liability.
Authorization-related flags (PA, ST, QL, M, AGE)
Entries flagged with administrative indicators — (PA), (ST), (QL), (M), (AGE) — indicate program controls that affect coverage. Review the formulary flags carefully and meet the associated requirements when prescribing or dispensing.
- (PA) = Prior authorization required.
- (ST) = Step therapy required (trial/failure of specified alternatives).
- (QL) = Quantity limits apply; requests above limits may need PA.
- (M) = Medical necessity criteria apply.
- (AGE) = Age limits — member age must meet criteria.
Step therapy requirement (ST)
When (ST) appears next to a drug, the product requires step therapy. Coverage is provided only after documented trial and inadequate response or intolerance to required first-line alternatives. Include prior-treatment documentation when requesting PA for step-therapy drugs.
- Examples of drugs with (ST): some statins, levothyroxine entries, and other branded products shown with (ST).
- Provide dates, drugs tried, reason for failure or intolerance, and any relevant lab results when supporting a step-therapy exception request.
Documentation required for age limits (AGE)
Age limits (AGE) shown in the formulary must be documented in any prior authorization or exception submission. If a product is flagged (AGE) you must confirm the member meets the age-based criteria to receive coverage.
- Examples: vaccines and selected chronic therapies in the formulary list include (AGE) indicators.
- Include member date of birth and relevant clinical rationale when submitting PA or exception requests.
Formulary structure and scope
The formulary groups medications by clinical category and assigns each item a drug tier that determines cost sharing. A clinical/pharmacy review team evaluates efficacy, safety, and cost‑effectiveness on a recurring schedule to maintain the list. Administrative controls — including prior authorization (PA), quantity limits (QL), step therapy (ST), maintenance (M), and age limits (AGE) — are applied at the item level and must be satisfied for coverage at the assigned tier.
Key flags and terms
Drugs subject to step therapy requirements
| Requirement | Description / Policy |
|---|---|
| Step therapy (ST) | |
| Drugs marked with (ST) require trial and failure of an alternative (preferred) therapy before the requested drug is covered; step therapy most often applies to brand‑name drugs. |
| Agent(s) | Requirements noted |
|---|---|
| Diltiazem (e.g., Dilt‑XR, Diltiazem Er) | |
| Listed with requirement flags including (ST)(QL)(M) or (M) depending on formulation — indicates step therapy may apply to some Diltiazem products. | |
| Icosapent / Omega‑3 Acid Capsule | |
| Example entries show Requirements & Limits = (ST) or blank depending on item; referenced as therapies with ST indicated in formulary segments. | |
| Benzonatate | |
| Included among items in formulary segments where (ST)(QL) or (ST) flags appear — denoting step therapy may apply to some formulations. |
| When (ST) is present | Policy implication |
|---|---|
| Requirements & Limits column includes (ST) | |
| Products with (ST) require documentation of prior trial and failure of preferred agent(s) before coverage is approved; prior steps must be documented per formulary rules. |
| Context | Action required |
|---|---|
| Formulary entries where (ST) indicated (e.g., diabetes testing & supplies and device kit listings; other therapeutic areas) | |
| Step therapy is required for drugs/items flagged with (ST); providers must document that required prior therapies were tried and failed (or were not tolerated) before the requested product will be covered. |
| Product | Requirement flags |
|---|---|
| Levothyroxin | |
| Requirements & Limits = (ST)(QL)(M) — indicates step therapy may be required for some Levothyroxin formulations in addition to quantity limits and medical necessity review. |

OpenPayer is powered by Trek Health's payer performance platform. Trek continuously ingests, validates, and normalizes Transparency in Coverage data alongside payer policies and other commercial payer data to create a structured payer intelligence foundation. OpenPayer uses this foundation to deliver personalized search results, dynamically generated policy pages, and tailored policy monitoring based on each user's payers, specialties, billing codes, and areas of interest. The same intelligence powers broader payer performance workflows, including reimbursement benchmarking, contract evaluation, payer negotiations, and financial decision-making.
