Pnctr w/o fb of left great toe w damage to nail, sequela

This code signifies a puncture wound to the left great toe, specifically without a retained foreign body, that has resulted in damage to the toenail. The "sequela" designation indicates that this code is used for the long-term effects or complications of the initial injury, rather than the acute injury itself. This could include ongoing nail deformity, chronic pain, or recurrent infection stemming from the original puncture.

Use this code when documenting follow-up care for a patient who previously sustained a puncture wound to the left great toe, and the current encounter addresses a persistent issue related to the nail damage caused by that injury. Examples include evaluation for onychomycosis secondary to nail trauma, surgical correction of a deformed nail plate, or management of chronic paronychia resulting from the initial puncture. Do not use for the initial acute injury.

• Ensure documentation clearly links the current nail pathology to a previous puncture wound of the left great toe.
• Verify that no foreign body is currently present or was the cause of the ongoing nail damage.
• This "S" code for sequela is typically a secondary diagnosis, with a "T" code for the initial injury often being referenced in the patient's history.
