CMS snapshot: November 2, 2026Source link checked November 11, 2026
A source-file match is not a refund, coverage or patient-eligibility determination. No patient or claim details are needed.
What does this MFP lookup show?
Find an exact package NDC in CMS's selected-drug list and Maximum Fair Price data file, then keep the source date periods and price basis beside the result. This frozen copy retains all 556 source rows, including update history. It searches calendar years 2026 and 2027; it is not a live CMS query.
CMS's selected-drug page links the file and describes annual and additional recurring updates. Check that page for a newer version before relying on a dated record. A missing match here means only that this snapshot has no matching record for the entered NDC and selected period.
Read the date and price basis together
- Calendar year versus IPAY
- The year control checks whether the source effective/end interval intersects the selected year. IPAY is the source's initial price applicability year, kept separately in each record. An IPAY-2026 record can have a 2027 inflation-adjusted period in this file.
- NDC-9 MFP per Unit Price
- The exact source unit-price string. It is not the price for the entire NDC-11 package. The November 2 CSV has no NDC-11 package-price column, so this tool does not display or calculate one.
- Single MFP per 30 DES
- The source's separate 30-day-equivalent-supply price field, displayed as published. It is not a patient copay or a refund estimate. Blank fields are shown as “Not stated,” never as zero.
- Source history
- Other periods and records with an end date before their effective date remain inspectable, with their original dates, update type and remarks. End-before-effective records are excluded from the selected-year periods. An empty end date means no end date is stated in this snapshot, not that the record remains current indefinitely.
These descriptions refer to the exact columns and records in the November 2 CMS file. A lookup match does not establish whether a particular transaction qualifies for an MFP refund. CMS's April 2026 dispensing-entity FAQ, questions 3 and 9, distinguishes the selected-NDC file and the refund process. Use your approved transaction records and current CMS instructions for that separate task.
Two source-reading exercises
These original exercises use the November 2 snapshot to practice reading records. They are not patient or dispensing examples.
One NDC, two prices: which 2026 period applies?
Look up 00078-1231-20 for calendar year 2026. Does the first matching price describe the entire year?
Answer: No. The file shows January 1–May 31, 2026 with unit price $1.229167, followed by June 1–December 31, 2026 with unit price $5.521349. Both rows retain $295.00 in the separate Single MFP per 30 DES field. Keep the period and price basis attached to each record; do not turn either value into a package price.

A future effective date with an earlier end date: is that a 2027 period?
For the same NDC, the source also contains an effective date of 01/01/2027, an end date of 12/31/2026 and update type Deselect. Should choosing 2027 return its price as an applicable period?
Answer: No. Its end precedes its effective date, so it has no usable date interval. The lookup preserves the row as history rather than repairing its dates or presenting an applicable 2027 price. This is a source-record interpretation, not a clinical or coverage decision.

- CMS: Selected Drugs and Negotiated Prices. Current download link checked November 11, 2026. Describes the selected-drug data file and updates; the source page can change independently of this frozen lookup.
- CMS Negotiation Program Selected Drug List and Maximum Fair Price Data File, November 2, 2026. CSV and spreadsheet checked November 11. 556 rows, 406 distinct NDC-11s and 15 columns retained; source-row numbers count the CSV header as row 1. Some source rows concern later initial-selection cohorts; the interactive year scope remains 2026/2027.
- CMS: Medicare Transaction Facilitator FAQs for Pharmacies and Other Dispensing Entities, April 2026, questions 3 and 9. Supports the file-lookup/refund-process distinction, not a refund calculation or claim decision.
