Sprain of MCP joint of left middle finger, subs

This code signifies a sprain affecting the joint between the metacarpal bone and the first phalanx of the left middle finger. It indicates that the patient is receiving follow-up care for this injury, such as rehabilitation, cast changes, or medication adjustments, after the initial treatment phase.

This code is appropriate for encounters where a patient is being seen for ongoing management of a previously diagnosed left middle finger metacarpophalangeal joint sprain. This includes visits for physical therapy, re-evaluation of healing, or addressing complications that arise during the recovery period.

• Ensure documentation clearly states "left middle finger" and "metacarpophalangeal joint" to support this specific site.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use this code for the initial treatment of the injury; a code with an "A" seventh character would be appropriate for the initial encounter.
