Unsp inj flxr musc/fasc/tend l idx fngr at wrs/hnd lv, init

This code signifies an unspecified injury to the flexor muscles, fascia, or tendons of the left index finger. The injury is located specifically at the wrist or hand level, indicating a broad area of potential damage to the structures responsible for finger flexion.

This code is appropriate for initial encounters where a patient presents with a suspected injury to the flexor apparatus of the left index finger at the wrist or hand, but the specific nature or extent of the injury (e.g., strain, tear, laceration) has not yet been determined. It is used when documentation indicates an injury to these structures without further specificity.

• Only use for the initial encounter of the injury. Subsequent care will require a different seventh character.
• Ensure the documentation specifies the left index finger and the injury location at the wrist or hand level.
• Avoid if a more specific diagnosis (e.g., flexor tendon laceration, flexor muscle strain) is documented.
