Injury of digital nerve of unspecified thumb, sequela

This code signifies a long-term or late-effect condition resulting from a past injury to a digital nerve of an unspecified thumb. It indicates that the initial nerve damage has led to persistent symptoms or complications, such as chronic pain, numbness, or weakness, that are no longer acute.

Use this code when documenting a patient presenting with ongoing neurological deficits or symptoms in the thumb that are directly attributable to a previous digital nerve injury. This applies when the acute phase of the injury has passed, and the current encounter addresses the residual effects.

• Ensure documentation clearly links the current thumb nerve sequela to a previous injury.
• Verify that the laterality of the thumb is truly unspecified in the medical record before using this code.
• Do not use for acute or initial encounters for a digital nerve injury; reserve for follow-up or chronic care.
