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

Operative indication

Synthetic hospital operative record, September 9, 2026. An adult has a suspicious peripheral nodule in the right upper lung lobe. The operative plan is to obtain tissue and use the result to decide whether to proceed with a larger lung resection.

Signed diagnostic sequence

Through an open thoracic approach, the surgeon obtains a wedge biopsy of that right-upper-lobe nodule. Frozen-section examination identifies carcinoma. Based on the result, the surgeon completes a right upper lobectomy during the same operation.

Specimen map

The biopsy is from the anatomical location encompassed by the right upper lobectomy. The wedge and the remaining lobe have separate specimen labels. No biopsy is taken from a different lobe or an unresected lung location.

Procedure worksheet

A draft adds a biopsy line because the frozen-section result determined the decision for lobectomy. Apply the lung-specific NCCI rule, which addresses this same-location diagnostic sequence. Use the completed open resection and full authorized entry; do not infer a more specific cancer histology than the report provides.

Your coding worksheet

  1. Map the biopsy site against the resection.
  2. Identify whether a different unresected location is supplied.
  3. Apply the organ-specific inclusion despite the diagnostic purpose.
  4. Explain why separate containers do not change the anatomical relationship.

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 biopsy site is included in the lung tissue removed by the more extensive procedure.
  2. There is no documented biopsy at a separate unresected location.
  3. NCCI C.21 includes the same-location biopsy even when it informs the decision for the resection.
  4. Container labels preserve specimen identity but do not override the same-resection inclusion.
