Medicare Part D spending
CMS's Medicare Part D spending dataset reports gross spending on Xtampza ER of $232.75 million in 2024, across 371,096 claims and 50,981 beneficiaries. CMS's dataset states spending is gross drug cost and does not reflect manufacturers' rebates or other price concessions. Spending is the total paid by Medicare, plans and beneficiaries for the drug's claims, not what a patient pays.
| Year | Gross spending | Claims | Beneficiaries | Average spending per claim |
|---|---|---|---|---|
| 2024 | $232.75 million | 371,096 | 50,981 | $627 |
| 2023 | $250.04 million | 371,710 | 52,082 | $673 |
| 2022 | $259.80 million | 400,751 | 55,591 | $648 |
| 2021 | $240.89 million | 399,977 | 58,601 | $602 |

FDA safety program (REMS)
- Opioid Analgesic REMS (application NDA208090): listed as in force, with Elements to Assure Safe Use. Program dated July 9, 2012, last modified June 18, 2026. REMS@FDA program page.
A REMS is a safety program the FDA can require for a drug. Some restrict how it is prescribed or dispensed, for example through certified prescribers or pharmacies. This lists what the FDA's REMS@FDA files tie to the application; it does not say which prescribers or pharmacies take part, or whether a given patient needs the program.

Controlled-substance schedule
Oxycodone appears in the DEA schedules at Schedule II (21 CFR 1308.12(b)). This is a federal classification under 21 CFR Part 1308. It is not a statement about whether a patient can get the drug.

Medicaid use by state
CMS's State Drug Utilization Data records, for 2024, how many prescriptions each state's Medicaid program paid for under this drug's packages and what it reimbursed. The 10 states with the largest reimbursement are shown of 36 with data. Reimbursement is before the rebates manufacturers pay states, so it is not a net cost and not a price a patient pays.
| State | Medicaid-paid prescriptions | Medicaid reimbursed | Covers |
|---|---|---|---|
| NC | 9,864 | $5,295,954 | Fee-for-service only |
| PA | 6,802 | $3,936,685 | Fee-for-service only |
| AZ | 4,469 | $2,270,158 | Fee-for-service only |
| FL | 3,652 | $2,145,063 | Fee-for-service only |
| CO | 1,919 | $1,019,747 | Fee-for-service only |
| CA | 1,646 | $972,621 | Fee-for-service only |
| NY | 1,710 | $962,209 | Fee-for-service only |
| OH | 1,302 | $776,187 | Fee-for-service only |
| DE | 1,523 | $677,488 | Fee-for-service only |
| TX | 987 | $677,228 | Fee-for-service only |
Where the publisher suppresses small managed-care cells, a state's figure covers fee-for-service claims only and understates use (63 state and package figures are marked that way here). A state missing from the table means its figures were suppressed or not reported, not zero use.

Federal formulary status
TRICARE
The Defense Health Agency's TRICARE formulary files include 5 packages of Xtampza ER in the uniform formulary class NARCOTIC ANALGESICS AND COMBINATIONS. Each row counts packages by the list that names them and the status it gives. A status is a TRICARE listing, not a statement about what a plan will pay for you.
