Question:

Priorities/CS Extension--Lung: In the absence of a physician TNM, is there a hierarchy associated with coding extension when multiple imaging studies demonstrate different degrees of extension? See Discussion.

Discussion:

CT of the lung showing primary lesion and other nodules in another lobe or contralateral lung, subpleural nodules, etc. The PET scan did not show activity for the other nodules. What is our "hierarchy" for imaging studies when there is no physician staging?

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.

There is no hierarchy among the various imaging studies. Assign CS extension based on the report documenting the greatest extension.
