Last updated: 10/3/2025

What is a HCPCS Code?

HCPCS (Healthcare Common Procedure Coding System) codes are used to identify medical procedures, supplies, and services for billing purposes. These codes help standardize how healthcare services are reported and billed across different providers and insurance companies.

Detailed Description

This code represents a 10-milligram injection of triamcinolone acetonide, which is a corticosteroid medication given by injection. The 'not otherwise specified' (nos) designation means this code is used when the specific brand or formulation of triamcinolone acetonide doesn't have its own unique code. Triamcinolone acetonide is an anti-inflammatory medication that can be injected into joints, muscles, or other areas of the body to reduce inflammation and pain.

Additional Information

This is a billing code for the medication itself, not the administration procedure. The actual injection procedure would be coded separately. Triamcinolone acetonide injections are commonly used for various inflammatory conditions.
