Contusion of unsp great toe without damage to nail, sequela

This code signifies a healed injury or a late effect resulting from a bruise to the great toe, where the nail itself was not damaged at the time of the original injury. The patient may present with residual pain, stiffness, or other long-term complications directly attributable to the past contusion.

Apply this code when documenting a patient encounter for a sequela of a contusion to the great toe, and the medical record explicitly states that the nail was not involved in the initial injury. This is appropriate for follow-up visits addressing chronic issues stemming from the original trauma, long after the acute phase has passed.

• Always ensure the "S" seventh character is used for sequela, indicating a late effect.
• Verify documentation explicitly states "without damage to nail" to differentiate from codes involving nail injury.
• This code should be used as a secondary diagnosis, with the primary diagnosis reflecting the current condition or reason for the encounter.
