If a patient has both Invasive and CIS can both cancers be coded? And how does Paget’s Disease (which codes to Invasive and is listed as Excludes 1 under CIS) affects the coding?
I did some research and found a coding guideline that states “Code the subsite with the “invasive” tumor when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites”. I interpret that guideline as being able to code both cancers. Few days ago out team had a meeting with a coding academy instructor who stated that you shouldn’t code CIS if patient has invasive cancer.
thank you for any assistance provided.
