Injury of peripheral nerves of neck, sequela

This code signifies a long-term or late effect resulting from a previous injury to the peripheral nerves located in the neck region. This could include persistent pain, weakness, numbness, or other neurological deficits that arose directly from an initial acute injury to these nerves. The "S" in the 7th character indicates that this is a sequela code.

Use this code when documenting chronic neurological symptoms or conditions in the neck that are directly attributable to a past injury of the peripheral nerves. Documentation should clearly link the current neurological deficit to a previous neck injury and indicate that the acute phase of the injury has passed. This code is appropriate for conditions like post-traumatic cervical radiculopathy or brachial plexopathy where the initial injury occurred in the past.

• Always ensure documentation explicitly states the current condition is a "sequela" or "late effect" of a previous injury.
• Do not use this code for acute injuries; instead, use the appropriate acute injury code for the initial encounter.
• Consider additional codes to specify the exact nature of the neurological deficit (e.g., pain, weakness) if not fully captured by this code.
