Dislocation of MCP joint of right thumb, subs

This code describes a dislocated joint between the metacarpal bone and the first phalanx of the right thumb, specifically when the patient is receiving follow-up care for this injury. This indicates that the initial treatment for the dislocation has already occurred, and the patient is now in a healing or recovery phase.

Use this code for encounters where a patient is being seen for ongoing management, physical therapy, or follow-up after the initial reduction of a right thumb metacarpophalangeal joint dislocation. This applies to visits for monitoring healing, assessing stability, or addressing complications that arise after the acute injury and initial treatment.

• Ensure the encounter is for subsequent care, not the initial treatment of the dislocation.
• Verify the laterality is specifically the right thumb.
• Confirm the injury involves the metacarpophalangeal joint, not another joint of the thumb.
