Subluxation of MCP joint of right ring finger, init

This code signifies a partial dislocation of the joint connecting the metacarpal bone to the first phalanx of the right ring finger. The joint surfaces are no longer in complete apposition, but some contact remains. This injury typically results in pain, swelling, and limited range of motion in the affected finger.

This code is appropriate for documenting the initial assessment and treatment of a patient presenting with a subluxation of the metacarpophalangeal joint of their right ring finger. It should be used when the injury is acute and the patient is receiving active treatment for the condition.

• Ensure documentation clearly specifies "subluxation" rather than a full "dislocation" for accurate coding.
• Verify the laterality (right) and the specific digit (ring finger) are explicitly stated in the medical record.
• The "A" suffix indicates an initial encounter for this condition, meaning the patient is actively receiving treatment for the injury.
