Criteria and timeframes for reconsideration, adjustments, voids, appeals, and price reviews.
Denial resolution pathways
- Denied for third-party liability: bill third parties first and rebill Medicaid with EOB or proof of non-coverage within 12 months.
- Denied for recipient eligibility: verify eligibility, seek retroactive coverage, then rebill.
- Denied for non-coverage or coding issues: verify appropriate/current procedure codes for date/provider/recipient and resubmit corrected claim.
- Denied for missing service authorization: verify SA number submitted or contact the authorizing agency for instructions.
- Denied for exceeding timely filing: file an appeal within 180 days of the RA decision.

Provider Requirements, Overrides and Submission Guidance
Prior Authorization for Prescribed Medications
Certain medications on the Prior Authorized Drug List require prior authorization (PA) before Alaska Medical Assistance will cover them. The prescriber must request PA by calling Prime Therapeutics State Government Solutions at 800-884-3238 or faxing a completed PA form; in emergencies the pharmacy may call 800-884-3238 for an override authorizing up to a five-day supply, but the prescriber must still obtain PA or the pharmacy will not be reimbursed if PA is later denied.
- Request PA via Prime Therapeutics phone 800-884-3238 or fax a completed PA form.
- Emergency override may authorize up to a five-day supply, but subsequent PA must be obtained.
Step Therapy Authorization
Step therapy (step-edit) may auto-authorize some PA drugs when the recipient's pharmacy and medical claim history or diagnosis supports approval; if automated criteria are not met the prescriber must request PA from Prime Therapeutics at 800-884-3238.
- Automated step-edits evaluate claims/diagnosis history for approval.
- If criteria fail, prescriber must contact Prime Therapeutics (800-884-3238) to request PA.
PA Call Centers and Pharmacy-Level Overrides
PA requests, clinical override consideration, and pharmacy-level overrides are handled by Prime Therapeutics Medicaid Administration via the Clinical Call Center (800-331-4475), the Technical Call Center, or direct pharmacy level overrides; providers should contact the appropriate call center for override consideration for dollar limits, timely filing, lock-ins, ProDUR and other specified denial reasons.
- Clinical Call Center phone: 800-331-4475 (fax also provided where applicable).
- Validate submitted claim details (quantity, dates) before requesting overrides for dollar limits, timely filing, or lock-ins.
- Provider-level overrides (e.g., ProDUR, COB) are allowed using the designated override codes when conditions are met.
Cost Ceiling Overrides
Claims with a dollar amount exceeding the prescription medication cost ceiling will initially deny; the pharmacy must contact Prime Therapeutics at 800-884-3238 to request authorization to override the cost-ceiling edit when the medication is medically necessary.
- Contact Prime Therapeutics State Government Solutions (800-884-3238) to request a cost-ceiling override.
- Claims will initially deny until override is authorized.
Point-of-Sale submission and exception resolution guidance
Submit claims via the Point-of-Sale (POS) system to receive real-time eligibility, drug coverage, pricing, PA guidance and immediate adjudication; review POS exception (four-digit) codes, correct the underlying issue(s), and resubmit when appropriate.
- POS returns instant adjudication: pay or deny with exception codes.
- An exception is a four-digit code indicating eligibility, coverage, interaction, early refill, etc.; address the first exception and be aware additional exceptions may still apply.
- Correct errors identified by POS and resubmit the claim.
Prior authorization and overrides (claim field guidance)
Include prior authorization and override indicators on the claim: submit the prior authorization number in NCPDP field 43 (462-EV) and use Submission Clarification Code (420-DK) = 02 (Other Override) to bill greater than the maximum dispensing limit.
- Enter the PA number in Field 43 / 462-EV as provided by Alaska Medical Assistance.
- To bill over maximum dispensing limit, set Submission Clarification Code 420-DK = 02 (Other Override).
LTC/Hospice residence coding
Enter the Patient Residence Code (NCPDP 384-4X) to identify long-term care or hospice residence so LTC/hospice specific overrides and quantity-limit exceptions will apply.
- Use Patient Residence Code 384-4X (e.g., 4 = Assisted Living) for LTC overrides.
- Hospice residence coding enables bypass of some opioid daily quantity limits for hospice recipients.
340B billing requirement
For 340B drugs, submit Submission Clarification Code 20 (420-DK) and report the submitted ingredient cost or billed amount as the 340B acquisition cost (340B ceiling price); contract pharmacies must carve out Alaska Medicaid and may not bill for 340B product.
- Set SCC 420-DK = 20 for all 340B claims.
- Submitted ingredient cost must be the lesser of actual acquisition cost or 340B ceiling price; do not bill pre-rebate purchase price.
ProDUR override coding
When overriding a ProDUR denial, submit the DUR Professional Service (Intervention Code) in NCPDP field 440-E5 and the DUR Result of Service (Outcome Code) in field 441-E6 documenting the intervention and outcome per ProDUR guidance.
- Populate 440-E5 with the appropriate Intervention/Professional Service code.
- Populate 441-E6 with the corresponding Result of Service/Outcome code to adjudicate an overridden ProDUR alert.
Home infusion dispensing fee
For home infusion therapy provided to recipients not in long-term care, do not bill a dispensing fee; submit Dispensing Fee Submitted (412-DC) as $0.00 and bill the home infusion per diem instead. For home infusion provided in LTC, a dispensing fee may be submitted per compounded medication guidance.
- If patient is not in LTC, set 412-DC = $0.00 (no dispensing fee) and bill per diem.
- If patient is in LTC, follow compounded medication guidance to claim a dispensing fee where allowed.
Postage/freight claim submission
To claim postage/freight, submit Other Amount Claimed (480-H9) with qualifier 479-H8 = 03 (Postage Cost) and count 478-H7; a single postage amount per claim is allowed up to $16 and postage must be prorated across multiple prescriptions mailed together.
- Use 480-H9 for postage amount, 479-H8 = 03 to indicate postage, and 478-H7 for count.
- Per-claim postage reimbursement must not exceed $16 and must be prorated when shipping multiple prescriptions.
Service Authorization and Denials
Obtain and include required Service Authorization (SA) numbers when an SA is required; claims billed without the required SA are subject to denial and recovery/recoupment.
- Claims lacking required SA may be recovered as overpayments.
- Verify SA numbers on claims to avoid denials and potential recoupment.
Service Authorization Issues on Denied Claims
If a claim is denied for missing service authorization information, verify the SA number submitted and, if SA was not obtained, contact the authorizing agency for instructions; follow the authorizing agency's direction before resubmitting.
- Verify accuracy of the SA number submitted on the claim.
- Contact the authorizing agency if SA was not obtained to determine next steps.
Adjustments and Voids (provider steps)
Submit adjustments to correct paid claims (procedure codes, charges, days, third-party payments, SA updates) using an 837 replacement or AK-05 form; positive adjustments that increase payment must be submitted within 12 months of the date of service (or within 60 days of payment per other filing guidance). To void a paid claim, request a void (AK-05) when recipient/contract IDs are incorrect, services were not rendered, or Medicare subsequently paid—void requests have no time limit.
- Use AK-05 or 837 replacement for adjustments/voids as appropriate.
- Positive adjustments that result in additional payment must be submitted within 12 months of date of service.
- Void requests are granted with no time limit; always void claims paid by Medicare after Medicaid payment.
