Sprain of metacarpophalangeal joint of left thumb, subs

This code describes a ligamentous injury to the joint connecting the metacarpal bone of the left thumb to its proximal phalanx, occurring during the healing or recovery phase. It indicates that the patient is receiving follow-up care for a previously diagnosed and treated sprain of this specific joint.

This code is appropriate for encounters where a patient is seen for ongoing management, healing, or rehabilitation of a left thumb MCP joint sprain after the initial treatment. This includes visits for physical therapy, re-evaluation of healing progress, or management of residual symptoms following the acute injury.

• Ensure documentation clearly specifies the left thumb and the metacarpophalangeal joint.
• The "D" seventh character signifies a subsequent encounter, meaning the patient is in the healing or recovery phase.
• Do not use for initial injury treatment or for sequelae (late effects) of the injury.
