This dataset includes the percentage of patients who are receiving PCH-based outpatient chemotherapy treatment for all cancer types except leukemia who were admitted to the hospital or visited the emergency department for one of 10 conditions within 30 days after treatment. The dataset also includes the rate at which cancer patients have unplanned readmissions within 30 days of discharge from an eligible index admission. Finally, the dataset also includes the analysis of complications of a prostatectomy by comparing outcomes at the hospital/facility level during the year after prostate-directed surgery. > > — *Source: CMS feed metadata* **Keywords:** Medicare, Complications and Unplanned Hospital Visits - PPS-Exempt Cancer Hospital - National **Theme:** Medicare ## Coverage timeline 2024 🟩 · 2025 🟩 · 2026 🟩 3 of 3 years with snapshot releases — no gaps. ## Release history | Reporting period | CMS published | Loaded | Latest file | | ------------------------- | ------------- | ---------- | ----------- | | Snapshot as of 2026-04-21 | 2026-04-21 | 2026-05-15 | ✓ | | Snapshot as of 2026-01-26 | 2026-01-26 | 2026-02-28 | | | Snapshot as of 2025-10-14 | 2025-10-14 | 2025-11-28 | | | Snapshot as of 2025-07-16 | 2025-07-16 | 2025-08-06 | | | Snapshot as of 2025-01-08 | 2025-01-08 | 2025-02-27 | | | Snapshot as of 2024-10-10 | 2024-10-10 | 2024-12-14 | | ## Data dictionary
