Prescriptive Authority & Controlled Substances

Controlled-substance prescribing needs state authority plus a DEA registration; Schedule II never refills, and buprenorphine needs no waiver.

02 · Schedule IISchedule II: never refilled

03 · BuprenorphineNo X-waiver; one-time 8 h SUD training

Who may prescribe what

State law says whether; the DEA says how

Controlled substances need state authority plus DEA registration

DEA registration in each state of practice, renewed every 3 years

DEA covers only the schedules state law allows the NP

Full practice: prescribe under board-of-nursing authority alone

Reduced or restricted: may need a collaborative or supervisory agreement

Hospital-employed NP, within the job: hospital DEA number + suffix

Only if state law permits; outside that role, a personal registration

Full practice authority includes controlled substances. DEA regulations call NPs and PAs 'mid-level practitioners', with registration limited to what the state of practice allows. The hospital assigns the internal suffix code.

Schedules I–V

Abuse potential falls from I to V

Schedule I

No accepted medical use

Schedule II — high abuse potential

OxycodoneFentanylHydromorphoneMethadoneAmphetamines

Schedule III

KetamineTestosteroneCodeine combinationsBuprenorphine

Schedule IV

BenzodiazepinesZolpidemTramadol

Schedule V carries the least abuse potential.

Refills and time limits

Schedule II: no refills, ever no refills

Multiple C-II prescriptions may total up to a 90-day supply

C-II emergency oral order: written prescription within 7 days

Schedules III–IV: no more than 5 refills

III–IV: no fill or refill over 6 months after issue

Opioid safety

Check the PDMP before every opioid prescription when feasible check PDMP

At minimum: before the initial Rx, then at least every 3 months

Offer naloxone when prescribing opioids

Especially: prior overdose, SUD or sleep-disordered breathing

…or ≥ 50 MME/day, or concurrent benzodiazepines

Opioid + benzodiazepine or sedative: higher overdose risk offer naloxone

Acute pain: immediate-release opioid, lowest effective dose

Quantity no greater than the expected duration of severe pain

Many state laws mandate PDMP checks; the 3-month check applies to long-term therapy. For acute pain, a few days or less is often enough — the 2016 CDC '3 days or less, rarely more than 7' was replaced in 2022 by individualized duration. Reassess long-term opioid therapy at least every 3 months, more often at higher risk of OUD or overdose.

Buprenorphine and MATE training

X-waiver ended Dec 29, 2022: no waiver needed

Any DEA registrant may prescribe buprenorphine for OUD, no patient cap

Since June 27, 2023: one-time 8-hour SUD training attestation

MATE training is deemed met by addiction medicine/psychiatry board certification, or graduation from an APRN, PA, medical or dental program within 5 years of June 27, 2023 with ≥ 8 hours of SUD curriculum. State buprenorphine laws still apply, so state-specific limits may remain.

E-prescribing and telemedicine

Medicare Part D Schedule II–V: send electronically (EPCS)

Compliant when ≥ 70% of those claims are e-prescribed

SUPPORT Act; the 70% threshold applies since 2023, with small-prescriber and waiver exceptions. The Ryan Haight Act normally requires an in-person exam before telemedicine controlled-substance prescribing; COVID-era flexibilities are extended through December 31, 2026 — check DEA for a final rule or further extension.

Schedule II or Schedule III–IV prescription?

	Schedule II	Schedules III–IV
Examples	Oxycodone, fentanyl, hydromorphone, methadone, amphetamines	III: codeine combinations, ketamine, buprenorphine · IV: benzodiazepines, zolpidem, tramadol
Refills	Never	Up to 5
Time limit	Multiple prescriptions may cover up to a 90-day supply	No fill or refill more than 6 months after issue
Oral (phone) order	Emergency only; written prescription within 7 days	Allowed

Pearl

State law says whether you may prescribe it; the DEA says how — and Schedule II never gets a refill.
