Submit the Cigna Xyrem PA form with complete clinical documentation. If denied, you have 180 days for internal appeal and 4 months for Illinois external review under the Health Carrier External Review Act. First step: Verify your prescriber is enrolled in the Xyrem REMS program and gather sleep study documentation before submitting the PA request.

Coding Basics: Medical vs. Pharmacy Benefit

Xyrem (sodium oxybate) is almost always handled under the pharmacy benefit rather than medical benefit. This oral medication is dispensed through a single REMS-certified specialty pharmacy and billed using NDC codes, not traditional medical claim J-codes.

Pharmacy Benefit (Standard Path)

  • Claim type: NCPDP pharmacy claim
  • Billing method: NDC-based with quantity in mL
  • Prior authorization: Required through Cigna's pharmacy benefit management
  • Distribution: Only via Xyrem/Xywav REMS Success Program

Medical Benefit (Rare Exception)

  • HCPCS code: J8499 (Prescription drug, oral, non-chemotherapeutic, NOS)
  • NDC requirement: Must include 11-digit NDC on medical claims
  • Use case: Exceptional circumstances requiring medical claim processing
Note: For Cigna members, verify benefit coverage through the member portal or by calling the pharmacy benefit number on your insurance card.

ICD-10 Mapping for Narcolepsy

Accurate ICD-10 coding is critical for Cigna prior authorization approval. The specific code must match your clinical presentation and documentation.

Primary Diagnosis Codes

ICD-10 Code Description Documentation Requirements
G47.411 Narcolepsy with cataplexy Clear cataplexy episodes documented; triggers, frequency, muscle weakness patterns
G47.419 Narcolepsy without cataplexy Explicit statement that cataplexy is absent based on history and exam

Supporting Documentation for Both Codes

  • Sleep study results: Polysomnography (PSG) and Multiple Sleep Latency Test (MSLT)
  • MSLT criteria: Mean sleep latency ≤8 minutes and ≥2 sleep-onset REM periods (SOREMPs)
  • Specialist evaluation: Sleep medicine or neurology consultation
  • Functional impact: Documentation of daytime sleepiness affecting work, school, or safety
Tip: The Cigna Xyrem PA form specifically asks for MSLT results and SOREMP counts, so ensure these are clearly documented.

Product Coding: NDC, HCPCS, and Units

NDC Information

  • Primary NDC: 68727-100-01 (Xyrem sodium oxybate oral solution)
  • Manufacturer: Jazz Pharmaceuticals
  • Unit of measure: mL (milliliters)
  • Strength: 500 mg/mL sodium oxybate

Dosing and Unit Calculations

Standard adult dosing follows specific increments that are important for accurate billing:

  • Starting dose: 4.5 g per night (9 mL total)
  • Titration increments: 1.5 g per night (3 mL total)
  • Therapeutic range: 6-9 g per night (12-18 mL total)
  • Administration: Always divided into two equal doses, 2.5-4 hours apart

Pediatric Weight-Based Dosing

Weight Range Maximum Dose Billing Considerations
<20 kg Lower starting dose Requires weight documentation
20-<30 kg 6 g per night max Weight verification mandatory
30-<45 kg 7.5 g per night max 0.2 g/kg/day maximum
≥45 kg 9 g per night max Adult dosing applies

Frequent Pitfalls and Common Mistakes

Dosing and Unit Conversion Errors

  • Single vs. divided dosing: Failing to document twice-nightly administration
  • Formulation confusion: Mixing up Xyrem and Xywav dosing equivalencies
  • Valproate interaction: Missing required 20% dose reduction when used with divalproex

Documentation Gaps

  • Missing sleep studies: PA requests without PSG/MSLT documentation
  • Incomplete prior therapy: Insufficient documentation of failed first-line treatments
  • REMS enrollment: Prescriber not enrolled in required safety program
  • Specialist requirement: Non-specialist prescribers without consultation documentation

Billing Code Mismatches

  • Wrong ICD-10: Using G47.411 without cataplexy documentation or G47.419 with cataplexy present
  • NDC errors: Incorrect units or strength when billing pharmacy claims

FAQ

How long does Cigna prior authorization take for Xyrem? Standard PA requests receive responses within 5 business days. Urgent requests are processed within 24 hours when clinical urgency is documented.

What if Xyrem is non-formulary on my Cigna plan? You can request a formulary exception with clinical justification. Document medical necessity and why formulary alternatives are inappropriate for your condition.

Can I request an expedited appeal in Illinois? Yes, if waiting for standard appeal timelines would seriously jeopardize your health. Both Cigna internal appeals and Illinois external reviews have expedited pathways.

Does step therapy apply if I failed treatments in another state? Prior therapy documentation from any state should count toward step therapy requirements. Ensure complete records are submitted with your PA request.

What happens if my prescriber isn't REMS-enrolled? Xyrem cannot be prescribed without REMS enrollment. Your prescriber must complete the Xyrem/Xywav REMS Success Program certification before submitting any PA requests.

How much does Xyrem cost without insurance? Retail cash prices typically range around $18,968 per 3×180 mL bottles. Jazz Cares patient assistance programs may provide support for eligible patients.
