Spontaneous rupture of other tendons, unspecified thigh

This diagnosis code signifies a non-traumatic tear of a tendon located in the thigh, where the specific tendon involved is not documented. It indicates a sudden, unexpected rupture of a thigh tendon without an external force or injury causing it.

Use this code when the patient presents with symptoms and imaging consistent with a spontaneous tendon rupture in the thigh, but the physician's documentation does not specify which particular tendon (e.g., quadriceps, hamstring) is affected. This code is appropriate when the cause is clearly non-traumatic and the exact tendon is unknown.

• Only use this code when the specific thigh tendon is truly unspecified in the medical record.
• Avoid using this code if the documentation indicates a traumatic rupture; instead, look for codes in the S76.x series.
• Query the provider if possible to identify the specific tendon involved for more precise coding.
