Injury of digital nerve of right little finger, sequela

This code signifies a long-term or late effect resulting from a past injury to the digital nerve of the right little finger. This could manifest as persistent pain, numbness, tingling, or weakness in the affected digit, even after the initial acute injury has healed. The sequela indicates a residual problem directly attributable to the original nerve damage.

Use this code when documenting a patient presenting with ongoing neurological symptoms in their right little finger, and the medical record clearly links these symptoms to a previous, resolved injury of the digital nerve. This is appropriate for follow-up visits addressing chronic nerve-related issues stemming from an old trauma.

• Ensure documentation explicitly states the injury is a "sequela" or "late effect" of a prior digital nerve injury.
• This code requires a seventh character "S" to indicate sequela, as it represents the long-term consequences.
• Do not use this code for acute or current injuries; those would require different codes from the S64.4- series without the "S" seventh character.
