Question:

EOD-Extension--Lung: If LUL mass "crosses the pleural surface" into the LLL, do we assume this represents extension to the pleura? See discussion.

Discussion:

9/22/93 Left upper lobe lobectomy: 3 x 3 cm mass in the periphery of the LUL near the LLL. Multiple enlarged nodes around the aortic arch and within the pulmonary fissure.

9/22/93 Pathology: Moderately differentiated Adenoca. The neoplasm does cross the pleural surface into the segment of the lower lobe. Lower margin of resection is free of neoplasm. Six lymph nodes negative for metastatic carcinoma. Tumor staged as T2N0M0 Stage Ib by physician.

Is tumor extension coded 10 [confined to one lung] or 40 [extension to pleura]?

Answer:

For cases diagnosed 1998-2003:

Code the EOD-Extension field to 40 [extension to pleura]. The tumor has penetrated (extended to) the pleura.
