Traumatic ischemia of muscle, sequela

This code signifies a long-term or late-occurring consequence of insufficient blood flow to muscle tissue that was caused by a prior injury. It indicates that the initial traumatic event led to muscle damage due to lack of oxygen and nutrients, and the patient is now experiencing residual effects from that past ischemic episode.

Apply this code when documenting chronic muscle weakness, pain, contractures, or other persistent functional deficits directly attributable to a past traumatic event that resulted in muscle ischemia. This is appropriate for follow-up encounters where the sequelae of the original injury are being treated or evaluated, long after the acute phase has passed.

• Always link this sequela code to an external cause code (V, W, X, Y category) describing the original traumatic event, if known and still relevant.
• Do not use this code for acute traumatic ischemia; instead, use the appropriate acute T79.6XXA code.
• Ensure documentation clearly states the connection between the current muscle issue and a prior traumatic ischemic event.
