Answer:
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.A single negative pleural effusion by itself does not impact the coding of extension.
The SEER note does not alter the AJCC note and the AJCC note does not alter the SEER note. They are two separate statements from two separate staging authorities. Registries follow both notes. For this case, ignore the pleural effusion because there is no clinical judgment available and there was only one cytology on the effusion.
