External constriction of right thumb, sequela

This code signifies a lasting effect or complication resulting from an external constriction injury to the right thumb. This could manifest as chronic pain, nerve damage, circulatory issues, or functional impairment that persists after the initial injury has healed. It indicates that the constriction event is no longer active, but its consequences are still present.

Use this code when documenting a patient presenting with a current, long-term condition directly attributable to a past external constriction injury of the right thumb. This is appropriate for follow-up encounters where the sequelae are being treated or evaluated, rather than the acute injury itself. Examples include chronic paresthesia, stiffness, or vascular compromise in the right thumb due to a previous tight band or object.

• Always ensure documentation clearly links the current condition to a past external constriction injury of the right thumb.
• This "S" seventh character indicates a sequela, meaning the residual effects of a resolved acute injury.
• Do not use this code for the initial acute injury or for active external constriction.
