Injury of nerves at shldr/up arm, right arm, sequela

This code signifies a long-term or late effect resulting from a past injury to a peripheral nerve in the right shoulder or upper arm, excluding the axillary, musculocutaneous, radial, median, ulnar, or cutaneous nerves. These sequelae can manifest as chronic pain, weakness, sensory deficits, or functional impairment that persists after the initial injury has healed.

Apply this code when documenting a current condition directly attributable to a previous injury of an unspecified or "other" nerve in the right shoulder or upper arm. This is appropriate for follow-up visits where the patient presents with ongoing symptoms from an old nerve injury, such as persistent neuropathy or muscle atrophy. It should be used when the acute phase of the original injury has passed.

• Always use this code as a secondary diagnosis, following a code for the specific sequela (e.g., chronic pain, muscle weakness).
• Ensure documentation clearly links the current condition to a past nerve injury in the right shoulder/upper arm and specifies it's not one of the individually coded nerves.
• Confirm the "S" seventh character for sequela is appropriate, indicating a late effect rather than an acute injury.
