Unsp inj unsp musc/tend at lower leg level, unsp leg, subs

This code signifies an unspecified injury to the muscles and/or tendons in the lower leg, without specifying which particular muscle or tendon is affected, and without laterality. The "D" suffix indicates this is a subsequent encounter for care after the initial treatment phase, such as during routine follow-up or rehabilitation.

Use this code when documentation indicates a patient is receiving follow-up care for a lower leg muscle or tendon injury, but the specific muscle/tendon or type of injury (e.g., strain, tear) is not clearly identified. It is appropriate when the initial treatment has concluded and the patient is in the healing or recovery phase.

• Only use this code when the specific muscle(s) or tendon(s) involved are not documented.
• Ensure the encounter is truly subsequent; if it's the initial treatment, a code with an "A" suffix is required.
• Avoid this code if a more specific diagnosis (e.g., strain of gastrocnemius) is available and documented.
