New York controlled substance supply limits cap most prescriptions at a 30-day supply, tighten to a seven-day supply for an initial opioid prescription treating acute pain, and allow up to a 90-day supply (or 180 days for anabolic steroids) when the practitioner writes a qualifying condition code on the prescription. These rules sit under Public Health Law Section 3331 and Title 10 NYCRR Part 80, and they work alongside New York’s electronic prescribing mandate and Prescription Monitoring Program checks.
The Standard 30-Day Supply Limit
For most controlled substance prescriptions in New York, the default ceiling is a 30-day supply. The rule applies across schedules and requires the practitioner to reassess the patient’s need before writing the next prescription. That monthly cadence is the reason patients on ongoing controlled substance therapy typically see their prescriber every few weeks rather than picking up a large refill.
The 30-day rule is the baseline. Two things move a prescription off that baseline: an initial opioid prescription for acute pain, which is capped tighter, and a qualifying chronic condition, which can extend the supply.
The Seven-Day Cap on Initial Opioid Prescriptions for Acute Pain
Public Health Law Section 3331 bars a practitioner from prescribing more than a seven-day supply of any Schedule II, III, or IV opioid when first treating a patient for acute pain.1New York State Senate. New York Public Health Law 3331 The statute defines acute pain as pain from disease, trauma, or another cause that the practitioner reasonably expects to resolve in a short period. On a follow-up visit for the same pain, the practitioner may issue a renewal, refill, or new prescription under the standard rules.
Section 3331 uses the phrase “initial consultation or treatment” without setting a specific lookback window, so whether a given visit counts as “initial” turns on the practitioner’s clinical judgment and any Department of Health guidance rather than a bright-line number of days.1New York State Senate. New York Public Health Law 3331
When the Seven-Day Cap Does Not Apply
The seven-day limit is narrower than many patients assume. Section 3331 carves out four categories of pain that fall outside the cap:1New York State Senate. New York Public Health Law 3331
- Chronic pain that has persisted beyond the expected healing period.
- Pain treated as part of an active cancer diagnosis.
- Hospice or end-of-life care.
- Palliative care focused on quality of life rather than curing the underlying illness.
Patients in any of these categories are prescribed under the standard supply rules, not the seven-day window. If you are being treated for cancer pain or long-standing chronic pain, you do not need to return every week for a new opioid prescription.
Extended Supplies Through Condition Codes
Title 10 NYCRR Part 80 lets a practitioner exceed the 30-day standard for patients with certain chronic or long-term conditions. When the prescriber writes a designated condition code directly on the prescription, the pharmacy can dispense up to a 90-day supply. For anabolic steroids prescribed for qualifying medical reasons, the allowance runs to 180 days.
The practitioner writes either the letter code or spells out the qualifying condition on the prescription, and the pharmacist verifies the code before dispensing the larger quantity. Seven codes are recognized:
- Code A – Panic disorder.
- Code B – Attention deficit disorder.
- Code C – Chronic debilitating neurological conditions.
- Code D – Chronic or incurable pain.
- Code E – Narcolepsy.
- Code F – Hormone deficiency states and anemia (the 180-day category for anabolic steroids).
- Code G – Seizure disorders.
If a larger-than-usual prescription reaches the pharmacy without a code, the pharmacist will flag it and the fill will stall until the prescriber’s office responds. If you know you qualify, confirm the code is on the prescription before you leave the appointment. Condition codes travel inside the electronic prescription, and pharmacy software can flag any mismatch between the quantity and the code attached.
Federal Refill and Partial-Fill Rules on Top
New York’s supply limits sit on top of federal rules that govern refills and partial fills. Both layers determine what you can actually pick up.
Schedule II drugs cannot be refilled under federal law.2eCFR. 21 CFR 1306.12 – Refilling Prescriptions; Issuance of Multiple Prescriptions for Schedule II Controlled Substances Every new supply requires a new prescription. A practitioner may write multiple Schedule II prescriptions at one visit with staggered fill dates, but each is a standalone order rather than a refill.
Schedule III and IV drugs may be refilled up to five times within six months of the original prescription date, whichever comes first.3eCFR. 21 CFR 1306.22 – Refilling of Prescriptions After that, a fresh prescription is required regardless of what remains on the original authorization.
If a pharmacy can only partially fill a Schedule II prescription, federal law under the Comprehensive Addiction and Recovery Act gives you 30 days from the date the prescription was written to pick up the remaining quantity.4Federal Register. Partial Filling of Prescriptions for Schedule II Controlled Substances For emergency oral prescriptions, that window is 72 hours.
Electronic Prescribing and PMP Checks
Since March 2016, New York has required practitioners to transmit prescriptions electronically rather than on paper pads, under Public Health Law Section 281.5New York State Department of Health. Electronic Prescribing The mandate covers both controlled and non-controlled substances. For patients, the practical effect is that quantities, codes, and refill authorizations move directly from the prescriber’s system to the pharmacy, without a paper prescription passing through your hands.
Before prescribing a Schedule II, III, or IV controlled substance, a practitioner must also check the state’s Prescription Monitoring Program registry under the Internet System for Tracking Over-Prescribing (I-STOP).6New York State Department of Health. Narcotic Enforcement Laws and Regulations The registry shows a patient’s recent controlled substance history across providers and pharmacies statewide, and it lets the prescriber address any recent overlap directly before writing the new prescription.
