PET Scans for Oncologic Conditions: Personal History

on Tuesday, 07 May 2019. All News Items | FAQ


Our claims for FDG PET scans are being denied when reported with a personal history diagnosis code, Z85.XXX. Why is this happening?


CMS Transmittal 2200 (CR 10859) added the following note concerning PET scans for oncologic conditions (NCD 220.6.17) when reported with a personal history diagnosis:

Note: Whenever a personal history diagnosis code (Z85.XXX) is on a claim, the claim must also contain a diagnosis code from the list of covered C, D or R diagnosis codes.”

The transmittal referenced above includes a link to the NCD spreadsheet updates for the PET Scan diagnosis codes. You can find the updated list of covered diagnosis codes for PET scans and all other NCD ICD-10 code updates at the Medicare coverage ICD-10 webpage.
