Number of Cancer Cases with Diagnosis Codes

The Diagnosis Code tables were generated for all FFS and MA patients in the SEER file overall and then just among breast, prostate, lung and colorectal cancer patients. The FFS tables were generated from the MEDPAR, Outpatient, and Carrier claim files and the MA tables were generated from the Inpatient, Outpatient and Carrier encounter files.

Please note that the SEER file includes SEER-linked cases diagnosed from 1999 to 2019, but only SEER cases diagnosed from 2000 to 2019 from the expansion registries: Greater California, New Jersey, Louisiana, Kentucky, Greater Georgia, Idaho, New York, Massachusetts, and Texas. These tables are limited to those diagnosis codes with 11 or more patients in any given calendar year. These tables should be used as aides to give you an estimate of the prevalence of medical diagnoses among the SEER-Medicare cancer cases.
