HCPCS Code J3301

Overview

HCPCS Code J3301 is used to report the supply of triamcinolone acetonide, a corticosteroid medication, administered by injection at a dosage of 10 mg. Triamcinolone is commonly used for its anti-inflammatory and immunosuppressive properties and is frequently administered via intra-articular, intramuscular, or soft tissue injection depending on the clinical indication.

This code represents the medication itself only, not the injection procedure or evaluation and management services, which must be billed separately when applicable.

Key Facts About J3301

  • Service type: Injectable medication (corticosteroid)
  • Provider type: Physicians and qualified healthcare professionals
  • Medication included: Triamcinolone acetonide, 10 mg
  • Route of administration: Injection (route varies by clinical use)
  • Common clinical indications:
    • Joint inflammation or arthritis
    • Bursitis or tendinitis
    • Allergic or inflammatory conditions
    • Dermatologic or soft tissue inflammation
    • Chronic pain or musculoskeletal disorders

When to Use J3301

J3301 is appropriate when:

  • Triamcinolone acetonide is administered via injection
  • The dosage is billed in 10 mg increments (units must reflect total dosage used)
  • The medication is medically necessary and documented
  • The medication supply is reported separately from the injection procedure

Examples:

  • Intra-articular steroid injection for knee osteoarthritis
  • Soft tissue injection for bursitis or tendinitis
  • Intramuscular corticosteroid injection for inflammatory conditions
  • Use of triamcinolone as part of a pain management or orthopedic treatment plan

Documentation Requirements

To properly support J3301 billing, documentation should include:

  • Patient identifiers and date of service
  • Name of medication (triamcinolone acetonide)
  • Total dosage administered (number of 10 mg units billed)
  • Route and anatomical site of injection
  • Medical necessity for corticosteroid use
  • Lot number and expiration date (when required)

Clear documentation ensures accurate reimbursement, medication tracking, and audit readiness.

Reimbursement and Coding Considerations

  • J3301 is reimbursed by Medicare and many commercial payers when medically necessary
  • Units must accurately reflect the total milligrams administered
  • The injection procedure (e.g., CPT® 20610, 96372) is billed separately
  • E/M services may also be billed separately if significant and distinct
  • Payer-specific rules may apply regarding site of service and frequency

Always verify payer policies for injectable medications and unit reporting.
