Unsp open wound of l mid finger w/o damage to nail, sequela

This code signifies a healed or residual effect of an open wound on the left middle finger, where the wound itself is no longer acute and the nail was not damaged. It indicates that the specific nature of the original open wound is not documented.

This code is appropriate for documenting the long-term consequences or late effects of a left middle finger open wound that has resolved, but where the exact type of open wound (e.g., laceration, puncture) was not specified in the initial encounter. It is used in follow-up encounters when the patient is seen for issues related to the previous injury after the acute phase has passed.

• Always assign a "S" (sequela) seventh character when coding for late effects or complications of a previous injury.
• Ensure documentation clearly states the injury is no longer acute and the patient is being treated for residual effects.
• Verify that there is no documentation of nail bed or nail plate damage to support the "without damage to nail" specificity.
