Subluxation of MCP joint of right index finger, subs

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the right index finger. The joint surfaces are no longer perfectly aligned, but still maintain some contact. This diagnosis indicates that the patient is receiving follow-up care for this specific injury.

Apply this code when a patient presents for ongoing treatment, such as physical therapy, follow-up imaging, or re-evaluation, for a previously diagnosed subluxation of the right index finger's metacarpophalangeal joint. This code is appropriate after the initial acute phase of injury.

• Ensure documentation clearly specifies the right index finger and the metacarpophalangeal joint.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use this code for initial treatment of the injury; refer to the "A" seventh character for initial encounters.
