Extended- Release Buprenorphine (XRB)

Extended‑release buprenorphine (XRB) can improve treatment stability for people with opioid use disorder, but access is often complicated by insurance rules, billing pathways, and cost concerns. With some approaches, clinics can provide XRB with less cost to patients while keeping this service a financially sustainable option.

Before offering XRB, clinics must have DEA registration, REMS certification, secure storage, and appropriate documentation templates. Once in place, clinics typically use one of two pathways: buy & bill or patient‑supplied (also referred to as “white bagging”). Buy & bill allows same‑day injections, flexibility in using the dose for any patient and might generate clinic payment to support the program. The downsides are that it requires upfront medication purchasing and patients may not know their full deductible/financial liability until after the claims are processed. Patient‑supplied dosing offers clearer patient cost expectations but can involve delays, can lead to waste and may not positively affect clinic finances.

For those with commercial insurance coverage, deductibles are one decision driver. Insurance coverage varies. Early in the year, patient‑supplied dosing can help patients meet deductibles without surprise bills. Once deductibles are met, buy & bill can result in minimal or no out‑of‑pocket cost and may support clinic sustainability. Most commercial plans cover XRB under either pharmacy or medical benefits and allow copay assistance, though some plans require careful timing and planning. Maine Medicaid covers XRB under buy & bill if authorization criteria are met and documented and under patient-supplied with prior authorization. Medicare typically covers buy and bill at about 80% (as a medical or Part B benefit), with the remaining costs possibly covered by secondary insurance.

Bottom line: XRB access can be achievable with some effort. By focusing on insurance pathways, deductible status and copay assistance, clinics can reduce barriers, keep patients engaged in care, and support long‑term recovery.
