Standard Analytical Files

These files are available by type of claim. Subject to privacy release approval, you may order 5% sample files for each claim type. The 5% sample is created based on selecting records with 05, 20, 45, 70 or 95 in positions 8 and 9 of the Health Insurance Claim (HIC) number. You may request extracts from the 100% data based on beneficiary identification number, state of residence, diagnosis code, provider type or location. Please see the Data Use Checklist for all options. The term ‘providers' is used universally to refer to physicians, as well as, institutions.

These files contain final action claims data in which all adjustments have been resolved. Files are scheduled to be released in late November.
