Last Updated: January 29, 2026

Medical Coding Assistant

Select a tool below to quickly look up rules or auto-code clinical notes.

While 20610 covers major joints (shoulders, knees, hips), smaller joints have their own specific CPT codes based on anatomic size. Using the wrong code will result in an immediate anatomic denial.

TL;DR Quick Answer

20600: Small Joints

CPT 20600 is for small joints or bursae. This strictly includes the fingers and toes (e.g., PIP, DIP, MCP, MTP joints).

20605: Intermediate Joints

CPT 20605 is for intermediate joints or bursae. This includes the wrist, elbow, ankle, temporomandibular joint (TMJ), and acromioclavicular (AC) joint.

Compare CPT Codes

Confused between with vs. without contrast? Look up the official code descriptions.

Ultrasound Variants (20604 and 20606)

If ultrasound guidance is used, you must use the corresponding US-inclusive codes rather than billing 76942 separately:

  • Small joint WITH ultrasound: 20604
  • Intermediate joint WITH ultrasound: 20606

Verify Medical Necessity

Don't risk a denial. See if your ICD-10 code is on the approved Medicare LCD list.

NCCI Edits

If injecting multiple fingers (e.g., right index and right middle finger), use the appropriate F-modifiers (e.g., F6, F7) to differentiate the digits on the claim.
