Sprain of MCP joint of left index finger, subs

This code signifies a sprain affecting the joint connecting the metacarpal bone to the proximal phalanx of the left index finger. It indicates that the patient is receiving follow-up care for an injury that has already been treated, such as during a rehabilitation visit or medication refill.

Use this code for encounters where a patient is being seen for ongoing management or healing of a previously diagnosed sprain of the left index finger's MCP joint. This includes visits for physical therapy, re-evaluation of healing progress, or management of residual symptoms after the initial acute treatment phase.

• Ensure documentation specifies the left index finger and the metacarpophalangeal joint.
• The "D" seventh character indicates a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use for initial treatment of the injury; refer to the "A" seventh character for acute care.
