Subluxation of MCP joint of right ring finger, subs

This code signifies a partial dislocation of the joint connecting the ring finger's metacarpal bone to its proximal phalanx on the right hand. The "subsequent encounter" designation indicates that the patient is receiving follow-up care for an injury that occurred previously, not the initial treatment.

Use this code when a patient presents for ongoing management, such as physical therapy, re-evaluation, or follow-up imaging, for a previously diagnosed subluxation of the right ring finger's metacarpophalangeal joint. It is appropriate for encounters after the initial treatment of the injury.

• Ensure the documentation clearly specifies the right ring finger and the metacarpophalangeal joint.
• Verify that the encounter is for follow-up care, not the initial treatment (which would use an 'A' or 'D' seventh character).
• Always sequence this code with an external cause code to describe the circumstances of the injury.
