J3301 and NDC Codes: Different Systems for Procedures vs. Drugs

CPT J3301 = Injection, triamcinolone acetonide, per 10 mg (a procedure/administration code).
NDC (National Drug Code) = unique identifier for a specific drug product (manufacturer, strength, package size).

Key Distinction

• CPT/HCPCS codes describe services/procedures (what was done).
• NDC codes identify drug products (what was used).
• No direct mapping: one CPT code can correspond to many NDCs (different brands, vials).

Billing Requirement

Many payers (especially Medicaid) require both on claim: CPT for administration + NDC for drug, with units and qualifiers (UN, ML, GR, F2).

Always verify payer-specific NDC reporting rules.
