Title 42 › Chapter 7— SOCIAL SECURITY › Subchapter XIX— GRANTS TO STATES FOR MEDICAL ASSISTANCE PROGRAMS › § 1396w–3a
Starting October 1, 2021, states must make sure that health care providers check a patient’s prescription history in a qualified prescription drug monitoring program (PDMP) before prescribing a controlled substance. If a provider tries but cannot check the PDMP, the provider must write down the reason and may have to show that note to the state. States must run PDMPs that give near real-time access to a patient’s controlled‑drug history for at least the past 12 months, show how many and what kinds of controlled drugs were prescribed and filled, and list who prescribed them. The PDMP must be able to work inside the provider’s regular workflow or electronic prescribing system. The federal government will explain privacy rules for sharing this data. The requirement can be waived during natural disasters, similar emergencies, or for emergency medical care. States can also require pharmacists to check the PDMP before they dispense controlled drugs. Each state must report yearly starting in 2023 on how often providers check the PDMP, trends in prescribing (including daily morphine milligram equivalents, per‑person amounts, and types of drugs with dates and supply lengths for groups like the elderly, people with disabilities, and dual enrollees), whether pharmacists must check, and any PDMP data breaches and how they were handled. By October 1, 2023, CMS must post guidance for increasing provider use and best practices. For any quarter in fiscal years 2019 or 2020, a state that linked its PDMP with all neighboring states so providers can access the required information gets a 100% federal match for PDMP development costs. Definitions: controlled substance = at least Schedule II drugs (states may include Schedule III or IV); covered individual = a person enrolled in the state’s Medicaid plan with some medical or residency exceptions; covered provider = a Medicaid prescriber (or designee), with certain provider types possibly exempted by the Secretary by October 1, 2020 after consultations.
