Coding Basics: Medical vs. Pharmacy Benefit Paths

Thiola/Thiola EC (tiopronin) can be covered under either your medical benefit (when administered in clinical settings) or pharmacy benefit (most common for oral tablets). Understanding which pathway applies affects your coding and prior authorization approach.

Medical Benefit Coverage:

  • Uses HCPCS J-code J7355 (effective July 1, 2024)
  • Billed by healthcare providers for in-office administration
  • Requires medical necessity documentation
  • May have different cost-sharing than pharmacy benefit

Pharmacy Benefit Coverage:

  • Most common pathway for Thiola/Thiola EC
  • Subject to formulary restrictions and prior authorization
  • Dispensed through specialty pharmacies
  • Uses NDC codes for billing
Tip: Check your Humana plan's drug formulary first to confirm Thiola's tier placement and whether step therapy requirements apply.

ICD-10 Mapping and Documentation Requirements

The primary diagnosis code for cystinuria is E72.01. This specific code is essential for all prior authorization requests and appeals.

Required Clinical Documentation

Laboratory Evidence:

  • 24-hour urine cystine measurement showing >500 mg/day
  • Urine microscopy showing cystine crystals (if available)
  • Kidney stone analysis confirming cystine composition
  • Current kidney function tests

Treatment History Documentation:

  • Evidence of attempted conservative measures (increased fluid intake, dietary modifications)
  • Trial of alkalinization therapy (potassium citrate, sodium bicarbonate) with outcomes
  • Documentation of failure, inadequacy, or intolerance to conservative treatments
  • Symptom history and functional impact

Specialist Requirements:

  • Prescription from urologist or nephrologist
  • Specialist consultation notes supporting medical necessity
  • Treatment plan including monitoring schedule

Counterforce Health specializes in helping patients and providers compile this exact documentation package, turning insurance denials into targeted, evidence-backed appeals that align with each payer's specific requirements.

Product Coding: HCPCS J-Code J7355 and NDC Guidelines

HCPCS Coding for Thiola/Thiola EC

J7355 is the designated HCPCS code for all tiopronin formulations, effective July 1, 2024. This includes both Thiola and Thiola EC (delayed-release) formulations.

NDC Requirements and Unit Calculations

Billing Units: Claims must specify the exact NDC matching the dispensed product strength:

  • Thiola EC 100 mg tablets
  • Thiola EC 300 mg tablets

Unit Conversion Examples:

Daily Dose Tablet Strength Tablets/Day 30-Day Supply
900 mg 300 mg 3 tablets 90 tablets
800 mg 100 mg 8 tablets 240 tablets
1200 mg 300 mg 4 tablets 120 tablets
Critical: Always bill by number of tablets dispensed, not total milligrams. Each tablet strength requires a separate line item with its specific NDC.

Frequent Coding and Billing Pitfalls

Common Unit Conversion Errors

Mistake #1: Billing total daily milligrams instead of tablet count

  • Wrong: 900 units for 900 mg daily dose
  • Right: 3 units for three 300 mg tablets daily

Mistake #2: Mixing tablet strengths on single claim line

  • Wrong: Combining 100 mg and 300 mg tablets as one NDC
  • Right: Separate line items for each strength with corresponding NDCs

Mistake #3: Incorrect HCPCS code usage

  • Wrong: Using outdated or non-specific codes
  • Right: J7355 for all tiopronin products (effective July 1, 2024)

Documentation Gaps That Trigger Denials

  • Missing 24-hour urine cystine quantification
  • Lack of specialist involvement (urologist/nephrologist required)
  • Insufficient evidence of conservative treatment failure
  • Incorrect or missing ICD-10 code E72.01
  • Incomplete dosing rationale or monitoring plan
