Every row carries lineage back to the exact CMS source file that produced it. ## Key facts | | | | ------------------ | ------------------------------------------------------ | | **Snowflake** | `DWV.MEDICARE_QUARTERLY_PART_B_SPENDING_BY_DRUG` | | **Databricks** | `cms_dwv.medicare_quarterly_part_b_spending_by_drug` | | **Coverage** | Jan 2025 – Mar 2026 | | **Rows** | 6,882 (total across all reporting periods) | | **Cadence** | Quarterly | | **Update pattern** | Time-partitioned — each file adds one reporting period | | **CMS published** | 2026-07-23 | | **Loaded** | 2026-07-23 | | **Columns** | 10 data + 6 lineage | | **Identifiers** | HCPCS codes | | **File versions** | 4 | | **License** | CMS public data — U.S. Government work | | **Platforms** | Snowflake Marketplace · Databricks Delta Sharing | Included in the CMS Data Feeds Dataset — [start a free trial on Snowflake Marketplace](https://app.snowflake.com/marketplace/listing/GZT1Z125KDH/dataplex-consulting-data-products-cms-data-feeds-dataset). {% hint style="success" %} **Current** — CMS last published this feed on 2026-07-23.

It also includes consumer-friendly descriptions of the drug uses, clinical indications, and manufacturer(s). > > Drug spending metrics for Part B drugs represent the full value of the product, including the Medicare payment and beneficiary liability. All Part B drug spending metrics are calculated at the HCPCS level. > > This dataset reports preliminary data that goes beyond the latest date available in the annual Medicare Part B Spending by Drug dataset. The data are updated each quarter and may change with each new release due to claims lag. Once an entire year of data is available with a sufficient run-out period, that data will move out of the preliminary quarterly dataset and into the annual Medicare Part B Spending by Drug dataset. Due to the preliminary nature of the quarterly dataset, we advise using caution when comparing between the annual and quarterly datasets. > > — *Source: CMS feed metadata* **Keywords:** Medicare, Original Medicare, Drugs **Theme:** Medicare ## Coverage timeline 2025 🟩 · 2026 🟩 2 of 2 years covered — no gaps. ## Release history | Reporting period | CMS published | Loaded | Latest file | | ----------------------- | ------------- | ---------- | ----------- | | 2026-01-01 – 2026-03-31 | 2026-07-23 | 2026-07-23 | ✓ | | 2025-07-01 – 2025-09-30 | 2026-04-30 | 2026-04-30 | | | 2025-04-01 – 2025-06-30 | 2026-01-29 | 2026-01-29 | | | 2025-01-01 – 2025-03-31 | 2025-12-11 | 2025-12-11 | | ## Data dictionary
