Unsp inj long flexor musc/fasc/tend thmb at wrs/hnd lv, subs

This code signifies an unspecific injury to the long flexor muscle, fascia, or tendon of an unspecified thumb, located at the wrist or hand level. This diagnosis is used during the recovery phase after initial treatment has been rendered for the injury.

Apply this code when a patient presents for follow-up care, such as cast changes, wound checks, or physical therapy, for a thumb flexor injury where the specific nature of the injury (e.g., strain, tear) was not documented or is unknown. It is appropriate for subsequent encounters after the initial treatment of such an injury.

• Ensure documentation clearly indicates a subsequent encounter for the injury.
• Only use this code when the specific long flexor muscle, fascia, or tendon injury of the thumb is not further specified.
• If the laterality (left or right thumb) is documented, a more specific code should be used.
