A dural leak repaired during the operation

Read an original fictional chart, identify the supported facts, and explain your coding workflow.

Chart gym · Original fictional record

Service date: 2026-09-09 · Professional operative service; cited Medicare NCCI relationship

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

Procedure context

Fictional adult undergoes a documented lumbar decompression. The surgeon identifies the operative level and planned work in the full report. The exercise concerns repair of a dural leak arising during that operation, not selection of the final decompression entry.

Intraoperative event

During the decompression, the report documents an unintended dural opening with cerebrospinal fluid leakage. The surgeon recognizes it immediately and repairs it before completing the same operation. The event and repair remain in the operative record.

Encounter timeline

The patient remains in the same operating room under the same operative encounter. There is no later return to surgery, separate date or unrelated preexisting leak treated during another encounter. The documented repair addresses the opening caused during this operation.

Claim question

A proposed additional dural-repair procedure is based solely on the fact that a complication occurred. Apply the cited inclusion without suppressing the clinical event. The exercise does not authorize changing the diagnosis or procedure timeline to obtain another claim line.

Your coding worksheet

  1. Identify the leak’s cause and timing.
  2. Determine whether a separate return encounter occurred.
  3. Evaluate the proposed independent repair.
  4. Explain why included work still belongs in the record.

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 leak occurs during the described lumbar operation and is repaired before it ends.
  2. No separate return procedure is documented.
  3. NCCI C.12 includes repair of the leak arising during that spinal procedure.
  4. The clinical event remains accurately documented; inclusion concerns the procedure relationship rather than permission to erase a complication.
