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

This code signifies a long-term or late-effect complication resulting from a previous injury to the radial nerve in the patient's right upper arm. This could manifest as persistent weakness, numbness, or pain in the distribution of the radial nerve, affecting wrist extension, finger extension, and sensation over the back of the hand. The original acute injury has resolved, but its neurological consequences remain.

Use this code when documenting a patient presenting with ongoing neurological deficits directly attributable to a past radial nerve injury in the right upper arm. This applies to follow-up visits for chronic radial nerve palsy, nerve entrapment syndromes, or neuropathies that are a direct consequence of an earlier trauma. The "sequela" designation indicates that the initial injury is no longer acute.

• Always sequence this sequela code after the code for the specific late effect or complication (e.g., G56.31 for mononeuropathy of the radial nerve, right upper limb).
• Ensure documentation clearly states the right arm and the upper arm level of the radial nerve involvement.
• Verify that the patient's medical record explicitly links the current condition to a previous injury.
