Subluxation of oth carpometacarpal joint of unsp hand, subs

This code signifies a partial dislocation of a carpometacarpal joint, excluding the thumb, in an unspecified hand. This injury involves the bones at the base of the fingers (metacarpals) and the wrist bones (carpals) losing their normal alignment, but still maintaining some contact. The "subsequent encounter" indicates the patient is receiving follow-up care for this previously diagnosed condition.

Apply this code when a patient presents for ongoing treatment, such as physical therapy, cast changes, or re-evaluation, for a subluxation of a carpometacarpal joint (excluding the thumb) in either hand. This code is appropriate after the initial diagnosis and treatment have been rendered.

• Ensure documentation specifies "subluxation" and not a complete dislocation.
• Verify that the affected joint is not the carpometacarpal joint of the thumb, as that has a separate code.
• Confirm the encounter is for follow-up care, not the initial injury or a sequela.
