* Institutional and Physician/Supplier claims files are based on the same file structures year to year. Only file descriptions for the most recent year are shown. Starting with the 2010 Institutional Claims file, CMS altered the Institutional Claims file format by allowing up to 25 ICD-9 diagnosis codes and up to 25 ICD9 procedure codes. This required that the USRDS change the HOSP file structure. The file CKD_92_to_09_hosp_clm has up to 10 ICD-9 diagnosis codes and up to 10 ICD-9 procedure codes. The file CKD_ POST09_hosp_clm for year 2010 and beyond has up to 25 ICD-9 diagnosis codes and up to 25 ICD-9 procedure codes.
