Minnesota Subscriber

Answer: The correct code will depend on two questions:

  • Did the provider use a prosthetic implant during the encounter?
  • What is the specific anatomy of the arthroplasty?

When the provider performs arthroplasty on a patient’s metacarpophalangeal joint, you’ll report 26530 (Arthroplasty, metacarpophalangeal joint; each joint) for each joint he injects. If the shots include a prosthetic implant, then choose 25631 (… with prosthetic implant, each joint) instead.

When the provider performs arthroplasty on a patient’s interphalangeal joint, you’ll report 26535 (

Arthroplasty, interphalangeal joint; each joint) for each joint he injects. If the shots include a prosthetic implant, then choose 25636 ( … with prosthetic implant, each joint) instead.
