Coding Basics: Medical vs. Pharmacy Benefit

Trikafta is an oral prescription medication that's processed through the pharmacy benefit, not the medical benefit. This means:

  • Pharmacy claims use NDC codes and days supply calculations
  • No J-codes needed (those are for injectable/infusible drugs)
  • Prior authorization goes through pharmacy benefit management
  • Coverage follows formulary tiers, not medical necessity alone
Note: While HCPCS code J8499 exists for "oral non-chemotherapeutic drugs not otherwise specified," Trikafta claims typically process through standard pharmacy channels using NDC codes.

ICD-10 Mapping for Cystic Fibrosis

Your diagnosis code must accurately reflect your CF manifestations:

ICD-10 Code Description Documentation Keywords
E84.0 CF with pulmonary manifestations Chronic cough, sputum production, lung function decline, pulmonary exacerbations
E84.1 CF with intestinal manifestations Pancreatic insufficiency, malabsorption, failure to thrive, meconium ileus
E84.8 Other CF manifestations CF-related diabetes, liver disease, sinus disease
E84.9 CF, unspecified General CF diagnosis without specific organ involvement

Documentation must include:

  • CFTR genetic testing results (F508del mutation status)
  • Sweat chloride test results (>60 mEq/L diagnostic)
  • Clinical symptoms and organ system involvement
  • Prior therapy trials and outcomes

Product Coding: HCPCS, NDC, and Billing

NDC Codes and Packaging

Trikafta comes in specific NDC configurations (verify current NDC numbers with your pharmacy as these may change):

  • Morning tablets (elexacaftor 100mg/tezacaftor 50mg/ivacaftor 75mg)
  • Evening tablet (ivacaftor 150mg)
  • Pediatric formulations available for patients 2+ years

Dosing and Days Supply Calculations

  • Ages 6+ years: Standard adult dosing = 28-day supply
  • Ages 2-5 years: Weight-based dosing = variable days supply
  • Billing units: Each 28-day cycle = 1 billing unit for standard dosing
Tip: Always verify the patient's age and weight-based dosing requirements, as pediatric formulations have different NDC codes and days supply calculations.

Frequent Billing Pitfalls

Common Mistakes to Avoid

  1. Missing genotype documentation - Always include CFTR genetic test results
  2. Incorrect age-based dosing - Verify pediatric vs. adult formulations
  3. Incomplete prior therapy history - Document all previous CFTR modulators tried
  4. Wrong diagnosis codes - Use specific E84.x codes, not general respiratory codes
  5. Expired PA approvals - Track authorization renewal dates

Unit Conversion Errors

  • Standard dosing: 2 morning tablets + 1 evening tablet daily
  • 28-day supply: 56 morning tablets + 28 evening tablets
  • Quantity limits: Verify Humana's specific quantity restrictions per fill

Verification with Humana Resources

Before submitting your request:

  1. Check formulary status using Humana's drug search tool
  2. Verify current PA requirements - policies update regularly
  3. Confirm submission method - some plans prefer specific portals
  4. Review quantity limits and days supply restrictions
  5. Check for step therapy requirements or preferred alternatives
Important: Always use the most current PA forms from Humana.com/MedPA, as requirements change annually.
