Open bite of unsp thumb without damage to nail, sequela

This code describes the long-term effects or complications arising from an open bite injury to an unspecified thumb, where the nail was not damaged during the initial injury. It indicates that the patient is presenting for treatment of a condition that is a direct consequence of a past open bite wound to the thumb.

Use this code when documenting a patient encounter for a sequela (e.g., scar tissue, chronic pain, functional limitation) resulting from an open bite to the thumb that occurred in the past. This code is appropriate when the initial injury has healed, but its lasting effects are now being addressed.

• Always assign this 'S' (sequela) code as a secondary diagnosis, following the code for the specific sequela being treated.
• Ensure documentation clearly links the current condition to a previous open bite injury of the thumb.
• Verify that the original injury did not involve damage to the thumbnail, as this impacts code selection.
