Injury of digital nerve of left index finger, sequela

This code signifies a long-term or late-effect complication resulting from a past injury to a digital nerve in the left index finger. This could manifest as persistent numbness, tingling, pain, or weakness in the affected finger, even after the initial injury has healed. The sequela indicates that the nerve damage is not an acute event but rather a lasting consequence.

Use this code when documenting a patient presenting with residual symptoms directly attributable to a previous injury of a digital nerve in their left index finger. This applies to conditions like chronic neuropathy, persistent paresthesia, or long-term motor deficits that are a direct result of an old nerve injury. It should be used when the acute phase of the injury has passed.

• Always assign a sequela code (ending in "S") as a secondary diagnosis, following the code for the nature of the sequela (e.g., G90.50 for causalgia).
• Ensure documentation clearly links the current symptoms to a past injury of the left index finger's digital nerve.
• Verify laterality (left) and specific digit (index finger) are accurately reflected in the medical record.
