Separation of muscle (nontraumatic), unspecified site

This code signifies a spontaneous or atraumatic separation of muscle fibers, not due to an injury. It describes a condition where muscle tissue detaches or tears without an external force or trauma.

Use this code when documentation clearly indicates a nontraumatic muscle separation, such as a spontaneous rupture or tear, and the specific anatomical site is not documented. This code is appropriate when the physician's notes confirm the absence of an acute injury or external cause.

• Only use this code when the documentation explicitly states "nontraumatic" and the site is unspecified.
• Avoid using this code if a specific muscle or anatomical region is identified; instead, look for more specific M62.0- codes.
• Do not confuse with muscle strains or tears due to injury, which are coded to S-codes.
