Columns 10
| Column | What it means | Type |
|---|---|---|
Drug Productdrug_product | Primarily based on active ingredient(s), strength, dosage form, and route of administration of a drug group. In most cases, NDCs for drugs that are pharmaceutically equivalent are assigned to the same drug group. In some cases, additional parameters are included in defining a drug group. For example, package size is included as an additional delineation when there is a demonstrated variation in acquisition prices between package sizes for drugs in which the most cost effective package size cannot be purchased and easily repackaged for dispensing (e.g., topical creams and ointments). | string |
Brief Indication Descriptionbrief_indicationdescription | Short description of the indications for which the drug product is utilized for. | string |
Drug Classdrug_class | Drug class is based on whether a prescription is required for dispensing a drug product. If a prescription is required, the NDC is referred to as 'legend'. If a prescription is not required, the NDC is referred to as 'over-the-counter', or 'OTC'. | string |
Package Sizepackage_size | While most NADAC drug groupings will consist of all package sizes available, a separate NADAC rate may be calculated for package sizes within a drug grouping when the pricing unit is 'ML (milliliter)' or 'GM (gram)' and when there is a demonstrated variation in acquisition costs between package sizes for drugs in which the most cost effective package size cannot be purchased and easily repackaged for dispensing (e.g., topical creams and ointments). Drug forms with kits will also be evaluated for pricing per package size. These situations require the use of differential NADAC drug groupings that vary by package size. These NADAC rates are calculated for unique drug grouping / classification for rate setting / pharmacy type / package size combinations. | string |
NCPDP Billing Unit Standardncpdp_billing_unit_standard | The standard billing unit type for the drug product as outlined in the National Council for Prescription Drug Programs (NCPDP) database. | string |
NADAC Ratenadac_rate | The NADAC for the corresponding generic drug. | string |
Number of NDCs within Rate Groupnumber_of_active_ndcs_within_the_rategroup_that_are_on_the__0bb0 | The total number of National Drug Codes (NDCs) within the rate group. | string |
Primary Reason Codeprimary_reason_code | Describes the primary reason for the NADAC Per Unit change, see explanation below for each reason: • Survey Rate: The NADAC Per Unit has been updated using information from the most recently completed pharmacy survey. • WAC Adjustment: The NADAC Per Unit has been updated to reflect changes in published pricing. • Help Desk Adjustment: The NADAC Per Unit has been updated as a result of an inquiry to the help desk. • Brand Generic Change: The NADAC Per Unit has been updated as a result of a change in the Classification for Rate Setting. • Rate Group Change: The NADAC Per Unit has been updated due to placement into a new NADAC drug grouping because of a change in the NDC attributes. | string |
As of Dateas_of_date | Date the rate group first appeared on the NADAC. | date |
Classification for Rate Settingclassification_for_rate_setting | Indicates whether the NDC was considered brand ('B') or generic ('G') for the NADAC rate calculation process. If the NDC was considered brand ('B') and approved under an Abbreviated New Drug Application (ANDA), the indicator is shown as ('B-ANDA'). NDCs approved as biosimilar products are considered brand ('B') and will be designated as ('B-BIO'). | string |
