How to appeal a Highmark maternity & postpartum denial

The framework that applies to your appeal

Federal law gives you the right to a full and fair internal appeal, then an external review by an independent third party.

Highmark-specific note: Operates BCBS in PA (western), WV, DE, NY (western). Owns Allegheny Health Network.

What Highmark's policy requires for maternity & postpartum

Cited policy: BCBS Compounded 17-OHP Coverage Post-Makena Withdrawal

Makena withdrawn Apr 6, 2023 after PROLONG. Compounded 17-OHP coverage variable.

How Highmark denies maternity & postpartum — and how to counter it

Where Highmark pushes back: 1) Investigational following Makena withdrawal; 2) PROLONG failed confirmatory.

Counter-arguments that hold up: SMFM statement Oct 2023 supports shared-decision-making compounded 17-OHP in patients with prior spontaneous preterm birth despite PROLONG. Original Meis NEJM 2003 efficacy data unchanged for highest-risk subgroup. FDA withdrawal addresses regulatory standard for accelerated approval, NOT absence of clinical utility. State boards of pharmacy permit 503A/503B compounding. Document prior spontaneous PTB + cervical surveillance + shared decision-making note.

How to submit the appeal to Highmark

1. Read the denial letter — note the exact denial reason code and the appeal deadline (180 days from the date on the letter).
2. Gather supporting documentation: physician letter of medical necessity, relevant clinical notes, peer-reviewed citations supporting the treatment for your indication, and the policy or coverage document Highmark cited in the denial.
3. File the appeal through Highmark's portal (members: https://www.highmark.com ; providers: https://www.highmark.com/provider). Standard decision returns within 30 days; expedited urgent appeals return within 72 hours.
4. If denied again, request external review by an independent reviewer within 4 months of the final internal denial. In PA, the state insurance department coordinates external review for fully-insured plans; ERISA self-funded plans use a federal external review through DOL/EBSA.
