Injury of other nerves at forearm level, right arm, sequela

This code indicates a long-term or late effect resulting from a previous injury to a nerve in the right forearm, excluding the median, ulnar, and radial nerves. This could encompass damage to smaller, unnamed nerves or branches that are causing ongoing symptoms or functional deficits. The "sequela" designation signifies that the original acute injury has resolved, but its lasting consequences are still present.

Use this code when documenting a patient presenting with chronic pain, weakness, sensory disturbances, or other persistent neurological deficits in the right forearm, and the medical record clearly links these symptoms to a past injury of a nerve other than the major three. This applies after the initial healing period of the acute injury has passed.

• Ensure the documentation explicitly states "sequela" or indicates a chronic, residual condition from a past injury.
• Confirm the injury location is the right forearm and the affected nerve is not the median, ulnar, or radial nerve.
• Always code the underlying cause of the original injury, if known and still relevant, as a secondary diagnosis.
