Dislocation of MCP joint of right index finger, subs

This code signifies a dislocation of the joint connecting the metacarpal bone to the first bone of the right index finger. The joint has been completely displaced from its normal alignment. This specific code is used when the patient is receiving follow-up care for this injury, such as cast changes, physical therapy, or monitoring healing progress.

Apply this code for patients presenting for subsequent treatment of a previously diagnosed and treated dislocation of the right index finger's metacarpophalangeal joint. This includes encounters for rehabilitation, follow-up imaging, or evaluation of complications arising during the healing phase. Do not use for the initial treatment of the dislocation.

• Ensure documentation clearly specifies the right index finger and the metacarpophalangeal joint.
• Verify that the encounter is for subsequent care, indicated by the "D" seventh character.
• Confirm the injury is a true dislocation, not a subluxation or sprain.
