Injury of digital nerve of right index finger, sequela

This code signifies a long-term or late effect resulting from a past injury to a digital nerve in the right index finger. This could manifest as persistent pain, numbness, tingling, weakness, or altered sensation in the affected finger, occurring months or years after the initial nerve damage. The original acute injury is no longer present, but its lasting consequences are being addressed.

Apply this code when documenting conditions like chronic neuropathy, causalgia, or persistent sensory deficits in the right index finger that are directly attributable to a previous digital nerve injury. This is appropriate for follow-up visits where the sequelae of the original injury are being treated, rather than the acute injury itself.

• Always link this sequela code with an external cause code (V00-Y99) to describe the original event that caused the injury, if known.
• Do not use this code for acute or current nerve injuries; those require codes from the S64.4- category without the "S" seventh character.
• Ensure documentation clearly states the condition is a residual effect of a past injury to the right index finger's digital nerve.
