The Medicare Part D Opioid Prescribing Rates by Geography dataset provides information on geographic comparisons of the number and percentage of Medicare Part D opioid prescriptions at the state, county, and ZIP code levels.

The Medicare Physician & Other Practitioners by Geography and Service dataset contains information on use, payments, submitted charges, and beneficiary demographic and health characteristics organized by geography, Healthcare Common Procedure Coding System (HCPCS) code, and place of service.

The Medicare Outpatient Hospitals by Geography and Service dataset provides information on services for Original Medicare Part B beneficiaries by OPPS hospitals. These datasets contain information on the number of services, payments, and submitted charges organized by geography and comprehensive Ambulatory Payment Classification (APC).

The Medicare Inpatient Hospitals by Geography and Service dataset provides information on hospital discharges for Original Medicare Part A beneficiaries by IPPS hospitals. This dataset contains information on the number of discharges, payments, and submitted charges organized by geography and Medicare Severity Diagnosis Related Group (DRG).

The Medicare Geographic Variation by National, State & County dataset provides information on the geographic differences in the use and quality of health care services for the Original Medicare population. This dataset contains demographic, spending, use, and quality indicators at the state level (including the District of Columbia, Puerto Rico, and the Virgin Islands) and the county level. Spending is standardized to remove geographic differences in payment rates for individual services as a source of variation. In general, total standardized per capita costs are less than actual per capita costs because the extra payments Medicare made to hospitals were removed, such as payments for medical education (both direct and indirect) and payments to hospitals that serve a disproportionate share of low-income patients. Standardization does not adjust for differences in beneficiaries’ health status.

The Medicare Geographic Variation by Hospital Referral Region dataset provides information for researchers and policymakers to evaluate the geographic differences in the use and quality of health care services for the Original Medicare population. The dataset includes demographic, spending, use, and quality indicators at the hospital referral region (HRR) level.

The Medicare Part D Prescribers by Geography and Drug dataset contains information on prescription drugs prescribed by individual physicians and other health care providers and paid for under the Medicare Part D Prescription Drug Program. For each drug, the dataset includes the total number of prescriptions that were dispensed, which include original prescriptions and any refills, and the total drug cost. The total drug cost includes the ingredient cost of the medication, dispensing fees, sales tax, and any applicable administration fees and is based on the amount paid by the Part D plan, Medicare beneficiary, government subsidies, and any other third-party payers.

The Medicare Monthly Enrollment data provides current monthly information on the number of Medicare beneficiaries with hospital/medical coverage and prescription drug coverage, available for several geographic areas including national, state/territory, and county. The hospital/medical coverage data can be broken down further by health care delivery (Original Medicare versus Medicare Advantage and Other Health Plans) and the prescription drug coverage data can be examined by those enrolled in stand-alone Prescription Drug Plans and those enrolled in Medicare Advantage Prescription Drug plans. The dataset provides monthly and yearly enrollee trends.
