Unspecified sprain of unspecified thumb, sequela

This code signifies a past injury to an unspecified thumb, specifically an unspecified sprain, where the patient is now experiencing a residual condition or complication directly related to that original sprain. This could include chronic pain, stiffness, or limited range of motion that persists after the acute phase of the injury has passed.

Use this code when documenting a patient presenting with a long-term effect or consequence from a previously sustained, unspecified sprain of an unspecified thumb. This is appropriate when the initial injury has healed, but the patient continues to experience symptoms attributable to the original sprain.

• Ensure the medical record clearly links the current symptoms to a past thumb sprain.
• Only use this code when the specific thumb (right or left) and the specific ligament involved in the sprain are not documented.
• The "S" seventh character indicates a sequela, meaning the patient is being seen for a late effect of the injury.
