Injury of ulnar nerve at upper arm level, right arm, sequela

This code signifies a long-term complication or late effect resulting from a previous injury to the ulnar nerve in the right upper arm. This could manifest as persistent pain, numbness, weakness, or other neurological deficits in the distribution of the ulnar nerve, such as the little finger and part of the ring finger, and associated intrinsic hand muscles.

Apply this code when documenting a patient presenting with ongoing issues directly attributable to an old injury of the right ulnar nerve at the upper arm level. This is appropriate for follow-up visits addressing chronic symptoms like claw hand deformity, muscle atrophy, or sensory loss that developed after the initial acute injury has healed.

• Always use in conjunction with a code describing the specific sequela (e.g., muscle wasting, sensory deficit).
• Ensure documentation clearly links the current condition to a past ulnar nerve injury in the right upper arm.
• Verify the injury occurred at the "upper arm level" to differentiate from injuries at the elbow or forearm.
