Why North Carolina State Rules Matter

North Carolina's insurance laws provide crucial protections that work alongside Humana's coverage policies. Unlike ERISA self-funded employer plans, most individual and small group Humana plans in North Carolina must follow state regulations that can strengthen your position when appealing denials.

Key North Carolina protections for specialty medications:

  • 90-day transition coverage if your specialist leaves Humana's network while you're on Oxlumo
  • Emergency medication coverage with provider attestation (72-hour presumptive approval)
  • Specialist review requirement for denials (effective October 2025) - appeals must be reviewed by NC-licensed physicians in the same specialty
  • External review rights through Smart NC with binding decisions
Note: These protections apply to state-regulated plans. If you have an employer plan, check whether it's self-funded (ERISA) or fully-insured, as this affects which rules apply.

Scripts for Common Situations

Calling Humana Member Services

"Hi, I'm calling about a prior authorization request for Oxlumo, generic name lumasiran, for primary hyperoxaluria type 1. My member ID is [number]. Can you tell me the status of PA request number [if available] and what additional documentation might be needed? I have confirmed PH1 diagnosis and specialist involvement."

Requesting Expedited Review

"This is an urgent request for expedited prior authorization. My patient has primary hyperoxaluria type 1, a rare genetic disorder that can cause kidney failure. Delaying Oxlumo treatment could result in irreversible kidney damage. I'm providing clinical documentation showing confirmed AGXT mutation and elevated urinary oxalate levels."

Peer-to-Peer Review Request

"I'm requesting a peer-to-peer review for Oxlumo denial. As a nephrologist treating primary hyperoxaluria, I can explain why this FDA-approved orphan drug is medically necessary and why alternative treatments are inappropriate for this rare genetic condition."

FAQ

How long does Humana prior authorization take in North Carolina? Standard PA decisions take up to 30 days for Medicare Advantage plans. Expedited requests are decided within 72 hours if urgency is documented.

What if Oxlumo is non-formulary on my Humana plan? You can request a formulary exception with medical necessity documentation. Humana's exception process allows coverage for non-formulary drugs when medically necessary.

Can I get temporary coverage while waiting for approval? If transitioning to Humana or if formulary changes affect coverage, you may receive a 30-day transition supply. Request this immediately when starting a new plan.

Does North Carolina's external review cost anything? No. Smart NC external review is free for patients. The state pays for the independent medical review.

What if I have an employer plan through Humana? Check if your plan is self-funded (ERISA). Self-funded plans follow federal rules, not North Carolina state protections. Contact your HR department to confirm.

How do I prove medical necessity for a rare disease? Include genetic testing results, specialist consultation notes, FDA labeling showing approved indication, and peer-reviewed studies. Counterforce Health specializes in assembling this evidence for rare disease appeals.

Can I appeal if I'm denied during renewal? Yes. Renewal denials often focus on treatment response. Document urinary oxalate reduction and ongoing clinical benefit with your specialist.

What's the difference between internal and external appeals? Internal appeals are reviewed by Humana. External appeals are reviewed by independent medical experts through Smart NC. External review decisions are binding on Humana.
