Subluxation of carpometacarpal joint of unsp hand, sequela

This code describes a partial dislocation of a carpometacarpal joint, excluding the thumb, in an unspecified hand, that is a sequela. A subluxation indicates that the joint surfaces are still in partial contact, but their alignment is disturbed. The "sequela" designation means this is a residual effect or complication of an earlier injury.

Use this code for patients presenting with chronic or persistent symptoms related to a previously sustained subluxation of a carpometacarpal joint (other than the thumb) in either hand. This would apply when the initial acute injury has resolved, but the patient continues to experience pain, instability, or limited function attributable to the prior subluxation. It is appropriate for follow-up care of such chronic conditions.

• Ensure documentation clearly specifies "sequela" to justify this code.
• Verify that the affected joint is a carpometacarpal joint other than the thumb.
• Confirm laterality (unspecified hand) is appropriate if not documented.
