Unsp inj extn musc/fasc/tend l mid fngr at wrs/hnd lv, subs

This code signifies an unspecific injury to the extensor muscle, fascia, or tendon of the left middle finger, occurring at the wrist or hand level. The injury's exact nature (e.g., strain, tear) is not documented, and this code is used for follow-up care after the initial treatment.

This code is appropriate for subsequent encounters when a patient presents for ongoing management, physical therapy, or follow-up after an initial injury to the extensor structures of the left middle finger. It applies when the specific type of injury (e.g., laceration, rupture) was not or could not be determined at the time of the initial diagnosis.

• Requires a seventh character "D" for subsequent encounter, indicating ongoing care.
• Only use when the specific nature of the extensor injury is unspecified in the medical record.
• Ensure laterality (left) and digit (middle finger) are accurately documented.
