  • Therapeutic injection coding for non-IV medications (96372).
  • Correct coding for the drug product using HCPCS J-codes and units.
  • Coding for joint injections based on the joint injected (20600-small, 20605-intermediate, 20610-major).
Denial triggers

Missing or expired prior authorization for biologics.

Incorrect coding of infusion time or units of drug administered.

Billing for drugs or supplies included in the infusion code.

Lack of medical necessity documentation for the specific biologic.

Incorrect J-code for the drug administered.
