Subluxation of MCP joint of left ring finger, subs

This code signifies a partial dislocation of the joint connecting the left ring finger to the hand, specifically when the patient is receiving follow-up care for the injury. It indicates that the joint surfaces are no longer perfectly aligned but still maintain some contact.

Apply this code for patients presenting for ongoing treatment, such as physical therapy, cast changes, or follow-up evaluations, after initial treatment for a subluxation of the left ring finger's metacarpophalangeal joint. This code is appropriate for encounters occurring after the active treatment phase of the injury.

• Ensure the documentation clearly specifies "left ring finger" and "metacarpophalangeal joint."
• Verify that the encounter is for subsequent care, not the initial treatment of the injury.
• Confirm the physician's documentation supports a diagnosis of subluxation, not a complete dislocation.
