External constriction of left middle finger, sequela

This code indicates a lasting or late effect of external constriction affecting the middle finger of the left hand. This could be due to a previous injury where an external object, such as a ring or tight band, caused damage leading to ongoing symptoms or functional impairment. The "sequela" designation signifies that the acute phase of the injury has passed, and the current condition is a residual problem.

Use this code when documenting a chronic or residual condition of the left middle finger resulting from a past external constriction injury. This is appropriate for follow-up visits where the patient presents with ongoing pain, deformity, nerve damage, or circulatory issues directly attributable to the prior constriction. It should be applied when the initial injury is no longer active but its effects persist.

• Always ensure documentation clearly links the current external constriction issue to a past injury.
• Do not use for acute or initial external constriction injuries; those require codes from the initial encounter or subsequent encounter categories.
• Consider additional codes for specific sequelae, such as nerve damage (e.g., G56.81) or circulatory compromise (e.g., I73.89), if documented.
