Injury of other nerves at forarm lv, unsp arm, sequela

This code signifies a long-term or late effect resulting from an injury to a nerve in the forearm, where the specific nerve affected is not identified, and the laterality (left or right arm) is also unknown. It indicates that the initial acute injury has resolved, but the patient continues to experience residual symptoms or complications directly attributable to that past nerve damage.

Use this code when documenting a patient presenting with chronic pain, weakness, numbness, or other neurological deficits in the forearm that are a direct consequence of a previously sustained, unspecified nerve injury in that region. This applies when the original injury has healed, but its lasting impact is still present, and the affected arm was not specified in the original documentation.

• Always sequence this code after the code for the specific sequela (e.g., chronic pain, muscle weakness) it describes.
• Ensure documentation clearly links the current symptoms to a past forearm nerve injury and specifies the "sequela" nature of the presentation.
• Avoid using this code for acute or current nerve injuries; those require codes from the acute injury chapters.
