Important Operational Notes

Always verify claim identifiers before resubmission.
Maintain acquisition invoices and sourcing documentation.
Track repeated denials or pricing discrepancies.
Document all PBM communications and timelines.
Escalate patterns of under-reimbursement when identified.

Dealing with Denials: Stay Persistent

PBM denial responses frequently change and may vary between plans, PBMs, or contracts. Receiving denials is common and should be expected within the appeals process.

A denial does not end the process.

What To Do After an Appeal Is Denied

Carefully review the stated denial reason.
Determine whether the issue is:
- Administrative (missing data), or
- Pricing related.
If reimbursement remains below acquisition cost:
- Submit an external appeal, when available.
If systemic or unresolved issues persist:
- Consider filing a regulatory or plan complaint.

PBM processes often rely on pharmacies discontinuing follow-up.
Consistent documentation and escalation drive accountability.
