Open bite of left great toe without damage to nail, sequela

This code signifies a healed or chronic open wound on the left great toe that did not involve the nail. It indicates a past injury where the skin was broken, but the nail plate itself remained intact. The "sequela" designation means this is a residual effect or complication of an initial injury.

This code is appropriate for documenting follow-up care for a patient presenting with complications or ongoing issues related to a previously sustained open wound of the left great toe, specifically when the nail was not damaged. It would be used when the initial acute injury has resolved, but the patient is still being treated for a consequence of that injury, such as scar tissue, chronic pain, or non-healing issues.

• Ensure the documentation clearly specifies the left great toe and confirms the absence of nail damage.
• Verify that the encounter is for a residual effect or complication, not the initial acute injury.
• Consider if an external cause code (V, W, X, Y category) is also needed to describe the circumstances of the original injury.
