Identifies the drug name, strength, and dosage form of the drug product nadac_per_unit: 1. National Average Drug Acquisition Cost Per Unit effective_date: 1. Effective Date of the NADAC Per Unit Cost pricing_unit: 1. Indicates the pricing unit for the associated NDC ('ML', 'GM' or 'EA') pharmacy_type_indicator: 1. Source of pharmacy survey data used to calculate the NADAC 2. 'C/I' indicates data was collected from surveys of Chain/Independent pharmacies. otc: 1. Over-the-counter (OTC) Product ('Y' or 'N') explanation_code: 1. Codes that pertain to how the NADAC was calculated 2. Code 1: The NADAC was calculated using information from the most recently completed pharmacy survey. 3. Code 2: The average acquisition cost of the most recent survey was within ± 2% 4. of the current NADAC; therefore, the NADAC was carried forward from the previous file. 5. Code 3: The NADAC based on survey data has been adjusted to reflect 6. changes in published pricing, or as a result of an inquiry to the help desk. 7. Code 4: The NADAC was carried forward from the previous file. 8. Code 5: The NADAC was calculated based on package size. 9. Code 6: The CMS Covered Outpatient File drug category type of 'S/I/N' (Single 10. Source/Innovator/Non-Innovator) has not been applied. Most 'S/I' drugs with the 11. same strength, dosage form and route of administration were grouped together 12. for the purpose of the NADAC calculation and 'N' drugs were also grouped 13. together. In some cases, however, in calculating a NADAC, the CMS 'S/I/N' 14. designation was not applied when the state Medicaid brand or generic payment 15. practices for these drugs generally differed from the CMS Covered Outpatient 16. File designation. 17. Codes 7 through 10: Reserved for future use. classification_for_rate_setting: 1. Classification for Rate Setting" 2. Indicates whether the NDC was considered brand ('B') or generic ('G') for the NADAC 3. rate calculation process. If the NDC was considered brand ('B') and approved under an 4. Abbreviated New Drug Application (ANDA), the indicator is shown as ('B-ANDA'). corresponding_generic_drug_nadac: 1. Corresponding Generic Drug NADAC Per Unit 2. The NADAC for the corresponding generic drug. asofdate: 1. As of Date year: 1. As of Year month: 1. As of Month day: 1. As of Day generic_drug_effectime: 1. Corresponding Generic Drug Effective Date 2. The effective date of when the Corresponding Generic Drug NADAC Per Unit is 3. assigned to a multiple source brand drug NDC. This date may not correspond to the 4. NADAC effective date for the generic drug due to the method by which the 5. corresponding generic drug NADAC effective date is assigned. 6. The corresponding generic drug NADAC effective date is the latter of the following 7. dates: a) date of the NADAC reference file upon which the corresponding generic drug 8. NADAC first appears, b) the current corresponding generic drug NADAC effective date 9. plus one day – one day is added to the previous date so that there are no overlapping 10. rate segments, or c) the NADAC Effective Date for the generic drug group. This data 11. assignment process is necessary to eliminate the potential for applying corresponding 12. generic drug NADACs to past claims. generic_drug_effec: 1. Corresponding Generic Drug Effective Date 2. The effective date of when the Corresponding Generic Drug NADAC Per Unit is 3. assigned to a multiple source brand drug NDC. This date may not correspond to the 4. NADAC effective date for the generic drug due to the method by which the 5. corresponding generic drug NADAC effective date is assigned. 6. The corresponding generic drug NADAC effective date is the latter of the following 7. dates: a) date of the NADAC reference file upon which the corresponding generic drug 8. NADAC first appears, b) the current corresponding generic drug NADAC effective date 9. plus one day – one day is added to the previous date so that there are no overlapping 10. rate segments, or c) the NADAC Effective Date for the generic drug group. This data 11. assignment process is necessary to eliminate the potential for applying corresponding 12. generic drug NADACs to past claims. > dta obs: 5,303,778 vars: 16 1 Mar 2018 17:25 size: 726,617,586 (_dta has notes) ------------------------------------------------------------------------------- storage display value variable name type format label variable label ------------------------------------------------------------------------------- ndcdescription str59 %59s * NDC Description ndc str11 %11s * National Drug Code (NDC) nadac_per_unit double %10.0g * National Average Drug Acquisition Cost Per Unit effective_date int %td.. * Effective Date of the NADAC Per Unit Cost pricing_unit str2 %9s * Indicates the pricing unit for the associated NDC ('ML', 'GM' or 'EA') pharmacy_type_indicator str3 %9s * Source of pharmacy survey data used to calculate the NADAC otc str1 %9s * Over-the-counter (OTC) Product ('Y' or 'N') explanation_code str7 %9s * Codes that pertain to how the NADAC was calculated classification_for_rate_setting str6 %9s * Classification for Rate Setting corresponding_generic_drug_nadac double %10.0g * Corresponding Generic Drug NADAC Per Unit asofdate int %td.. * As of Date year int %9.0g * As of Year month byte %9.0g * As of Month day byte %9.0g * As of Day generic_drug_effectime str22 %22s * Corresponding Generic Drug Effective Date and Time generic_drug_effec int %td * Corresponding Generic Drug Effective Date * indicated variables have notes ------------------------------------------------------------------------------- Sorted by: ndc asofdate year month day
