Spontaneous rupture of flexor tendons, left thigh

This diagnosis code signifies a non-traumatic tear of the flexor tendons located in the left thigh. This condition typically results from degenerative changes within the tendon structure, rather than an acute external force or injury. Patients often present with sudden pain, weakness, and an inability to perform movements requiring the affected flexor muscles.

Use this code for patients diagnosed with a spontaneous, non-traumatic rupture of any flexor tendon in their left thigh. Documentation should clearly state "spontaneous" or "non-traumatic" rupture and specify the left thigh as the affected anatomical site. This code is appropriate when the rupture is not attributable to an external injury, overuse, or surgical complication.

• Ensure documentation explicitly states "spontaneous" or "non-traumatic" to differentiate from traumatic ruptures.
• Verify the laterality (left thigh) is clearly documented; separate codes exist for the right thigh and unspecified side.
• Do not confuse with traumatic tendon ruptures (S76.- codes) which are caused by an external injury.
