Injury of digital nerve of unspecified finger, subs encntr

This code signifies a documented injury to a digital nerve in any finger, where the specific finger affected is not specified in the medical record. It is used when the patient is receiving follow-up care for the initial injury, such as during rehabilitation, cast changes, or medication adjustments.

Apply this code for subsequent encounters when a patient presents for ongoing management of a previously diagnosed digital nerve injury of an unspecified finger. This includes visits for physical therapy, occupational therapy, or routine follow-up appointments after the initial treatment phase.

• Ensure the documentation clearly indicates a subsequent encounter for the injury.
• If the specific finger is identified, a more precise code from the S64.4- series should be used.
• Always sequence this code after any primary treatment codes or other relevant diagnoses for the encounter.
