Other rupture of muscle (nontraumatic), right thigh

This code signifies a spontaneous, non-injury-related tear or separation of muscle fibers within the right thigh. This condition typically results from underlying muscle weakness, overuse, or degenerative changes rather than an acute external force. Patients often present with sudden pain, swelling, and impaired function in the affected area.

Apply this code when documentation clearly indicates a non-traumatic rupture of a muscle in the right thigh. This includes scenarios where the tear occurred during normal activity, without a fall, direct impact, or other external injury. Physician notes should specify "spontaneous rupture," "non-traumatic tear," or similar language.

• Ensure the documentation explicitly states "non-traumatic" or "spontaneous" to differentiate from traumatic muscle ruptures.
• Verify laterality (right thigh) is clearly documented; separate codes exist for the left thigh and unspecified side.
• Do not confuse with muscle strains (S76.-) or contusions (S70.-) which are typically traumatic in nature.
