Plan
Fictional outpatient operative record describes elective laparoscopic sigmoid colectomy for a documented benign stricture. The decision to resect has already been made before surgery. This is a therapeutic operation, not a diagnostic laparoscopy to decide whether any open treatment is needed.
Attempted approach
After port placement, the surgeon begins mobilizing the sigmoid colon. Dense fixation prevents safe completion through the laparoscopic approach. The report records the limitation and conversion to a midline open approach during the same encounter. No separately indicated operation at another site is performed.
Completed anatomy
Through the open approach, the surgeon removes the diseased sigmoid segment and completes a colorectal anastomosis. No stoma is created. The report describes a completed resection and restored bowel continuity, followed by routine closure. These details guide review of the complete authorized entry.
Claim audit
The draft lists an open sigmoid resection and the attempted therapeutic laparoscopy. A suggested revision relabels the attempted laparoscopy as diagnostic. Evaluate both proposals using the conversion rule, while preserving the actual attempted approach and reason in the clinical record.
Your coding worksheet
- Identify the planned and completed approaches.
- Map removal and reconstruction.
- Evaluate the attempted laparoscopy line and proposed relabeling.
- Locate the full entry for the completed operation.
In your notebook, record the supported facts, your index route, the instructions you checked, and any missing detail that limits your answer.
Compare with the worked explanation
- The therapeutic laparoscopic attempt converts to a completed open operation.
- The sigmoid segment is removed and bowel continuity is restored by colorectal anastomosis; no stoma is documented.
- NCCI F.4 does not separately add the attempted surgical laparoscopy or relabel it diagnostic in this conversion.
- Use the complete open-operation entry and its component instructions. Preserve the conversion without making it a separately reportable procedure.
