Sprain of metacarpophalangeal joint of unsp finger, subs

This code signifies a sprain of the joint connecting the metacarpal bone to the first bone of an unspecified finger, occurring during the healing or recovery phase after the initial injury. It indicates ligamentous damage to this specific joint without specifying which finger is affected.

Apply this code for follow-up visits, cast changes, or physical therapy sessions for a metacarpophalangeal joint sprain of an unknown finger after the initial treatment has been rendered. It is appropriate when the patient is receiving active treatment for the sprain, but not for the initial injury or for sequelae.

• Ensure documentation clearly indicates a subsequent encounter for active treatment of the sprain.
• Avoid using this code for initial injury encounters; instead, use the appropriate initial encounter code.
• If the specific finger is documented, use a more specific code from the S63.65- series.
