Separation of muscle (nontraumatic), right forearm

This code signifies a spontaneous, non-traumatic separation or rupture of muscle tissue located in the right forearm. This condition is distinct from muscle tears caused by external injury or trauma. It often presents with sudden pain, swelling, and functional impairment of the affected forearm.

Apply this code when documentation explicitly states a non-traumatic muscle separation or rupture affecting the right forearm. This typically occurs due to underlying degenerative conditions, overuse, or metabolic disorders rather than an acute external force. Physician notes should clearly indicate the non-traumatic etiology.

• Ensure documentation specifies "non-traumatic" to differentiate from traumatic muscle injuries.
• Verify the laterality (right) and anatomical site (forearm) are clearly documented.
• Do not use this code for muscle strains or sprains; those have distinct codes.
