Injury of median nrv at upper arm level, right arm, sequela

This code signifies a long-term or late effect resulting from a past injury to the median nerve in the right upper arm. This could manifest as persistent weakness, numbness, tingling, or pain in the areas innervated by the median nerve, such as the thumb, index, middle, and part of the ring finger, or the forearm muscles. The original acute injury has resolved, but its neurological consequences persist.

Use this code when documenting a patient presenting with ongoing symptoms directly attributable to a previous median nerve injury in the right upper arm. This applies to conditions like chronic carpal tunnel syndrome secondary to a prior upper arm trauma, or persistent motor/sensory deficits after a healed fracture that involved the median nerve. The "S" seventh character indicates that this is a sequela, meaning the initial injury has passed the acute phase.

• Always sequence the sequela code first, followed by any codes for the specific manifestation of the sequela (e.g., carpal tunnel syndrome).
• Ensure documentation clearly links the current symptoms to a past median nerve injury in the right upper arm.
• Verify the laterality (right arm) is explicitly stated in the medical record to support this specific code.
