Injury of ulnar nerve at forearm level, unsp arm, subs

This code signifies a follow-up encounter for an injury to the ulnar nerve specifically located in the forearm region. The exact nature or extent of the injury is not specified, and the affected arm (left or right) is also not documented.

Apply this code for subsequent visits where a patient is receiving ongoing care, such as physical therapy, wound care, or follow-up evaluations, for an ulnar nerve injury in the forearm. This is appropriate when the initial injury has already been treated and the patient is in the healing or recovery phase.

• Ensure the documentation clearly indicates a "subsequent encounter" for the injury.
• Only use this code when the specific arm (left or right) is not documented by the provider.
• If the laterality is specified, use a more precise code from the S54.01- or S54.02- series.
