Injury of ulnar nerve at forearm level, left arm, sequela

This code signifies a long-term or residual effect from a past injury to the ulnar nerve in the left forearm. It indicates that the initial acute injury has resolved, but the patient continues to experience symptoms or deficits directly attributable to that original nerve damage. This could manifest as persistent weakness, numbness, tingling, or pain in the ulnar nerve distribution.

Use this code when documenting a patient presenting with ongoing symptoms related to a previously sustained ulnar nerve injury at the forearm level on the left side. This is appropriate for follow-up visits where the primary focus is managing the chronic sequelae, rather than an acute injury. It should be used after the initial healing phase of the acute injury has passed.

• Always sequence this code after the code for the specific sequela (e.g., muscle weakness, paresthesia) if applicable.
• Ensure documentation clearly supports the "sequela" aspect, indicating a past injury and current residual effects.
• Verify the laterality (left arm) and anatomical site (forearm level) are accurately reflected in the medical record.
