Use your code books and write your reasoning before opening the walkthrough. This exercise contains no real patient information.

Wound context

A fictional adult has a skin defect requiring closure after a documented procedure. The learner receives the closure portion of the record to distinguish direct repair from adjacent tissue transfer. The original procedure and any repair inclusion must also be checked before final reporting.

Closure technique

The surgeon describes freeing tissue beneath the wound edges by undermining, then bringing those edges together for direct closure. The report records the layers and length, but does not describe an adjacent flap being incised and carried into the defect.

Clarification boundary

The note calls the closure difficult. That adjective does not supply a missing flap design or movement. The coder should use the documented technique and compare the full repair definitions, requesting additional required detail if the selected definition needs it.

Proposed selection

A preliminary worksheet labels the service tissue transfer solely because undermining was extensive. No separate donor tissue or graft is documented. The exercise asks whether the supplied technique establishes the transfer pathway; it does not assign a final repair level.

Your coding worksheet

  1. Identify the actual closure technique.
  2. State the missing feature needed to establish tissue transfer.
  3. Explain why difficult work alone is insufficient.
  4. Complete the repair-definition and inclusion checks in the authorized reference.

In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.

Write your answer

Use only this fictional record. Your entries stay on this page and disappear when you leave or reload. Do not enter real patient information.

Compare with the worked explanation
  1. The record describes undermining followed by direct closure.
  2. It does not establish adjacent tissue incised and moved as a flap to close the defect.
  3. NCCI distinguishes extensive undermining from tissue transfer; an adjective cannot supply the missing technique.
  4. Investigate the supported repair pathway and its complete requirements, then check whether the original procedure already includes that repair.
