5.5 Opioid Prescribing Limits & Partial Fill Rights
Key Takeaways
- M.G.L. c. 94C, § 19D — not § 19E — limits a first-time outpatient opiate prescription to an adult to a 7-day supply, and caps ANY opiate prescription to a minor at a 7-day supply at any time.
- A practitioner may exceed the 7-day limit for an acute medical condition, chronic pain management, cancer-related pain or palliative care, provided the condition is documented in the medical record and the practitioner notes that a non-opiate alternative was not appropriate.
- The 7-day limit does not apply to medication used to treat substance use disorder or opioid dependence.
- Under M.G.L. c. 94C, § 18 a pharmacist filling a Schedule II prescription must, if the patient requests it, dispense a lesser quantity than prescribed.
- For a patient-requested partial fill the initial partial dispensing must occur within 5 days after the prescription issue date, and the remaining portion may be dispensed within 30 days after the issue date.
Opioid Prescribing Limits & Partial Fill Rights
Massachusetts was the first state to legislate a hard day-supply cap on initial opioid prescriptions, enacted by Chapter 52 of the Acts of 2016 and codified at M.G.L. c. 94C, § 19D.
[!WARNING] Cite § 19D, not § 19E. The opiate limit is § 19D. M.G.L. c. 94C, § 19E is an entirely different provision — it authorises statewide standing orders for COVID-19 control measures. Confusing the two is a common error in secondary study material.
The Two Caps
Adults — first time only. "When issuing a prescription for an opiate to an adult patient for outpatient use for the first time, a practitioner shall not issue a prescription for more than a 7-day supply." The cap attaches to the initial prescription. Subsequent prescriptions in a continuing course of treatment are not capped by this provision.
Minors — always. "A practitioner shall not issue an opiate prescription to a minor for more than a 7-day supply at any time." This is an absolute cap. It does not matter whether the minor is opioid-naive, whether it is a first prescription or a fifth, or how severe the injury is.
| Adult | Minor (under 18) | |
|---|---|---|
| First outpatient opiate prescription | Max 7-day supply | Max 7-day supply |
| Subsequent prescriptions | Not capped by § 19D | Still max 7-day supply |
The Exceptions
A practitioner may exceed the 7-day limit where, in the practitioner's professional medical judgement, more than a 7-day supply is required for:
- an acute medical condition;
- chronic pain management;
- cancer-related pain; or
- palliative care.
When the exception is used, the practitioner must document the condition in the patient's medical record and indicate that a non-opiate alternative was not appropriate to address the condition.
Separately, the limits do not apply to medication designed for the treatment of substance abuse or opioid dependence — buprenorphine and methadone prescribed for opioid use disorder are outside § 19D altogether.
[!IMPORTANT] The exceptions are the prescriber's to invoke, and the documentation lives in the medical record. A pharmacist presented with a 14-day opioid prescription for an adult cannot see the medical record. The pharmacist's tools are the PMP (to establish whether this patient is genuinely opioid-naive) and a call to the prescriber. The pharmacist does not have a statutory duty to police § 19D, but an unexplained day-supply anomaly is a red flag that engages corresponding responsibility under 21 CFR 1306.04.
Partial Fills of Schedule II Prescriptions — M.G.L. c. 94C, § 18
Massachusetts gives the patient a right, not merely an option:
"A pharmacist filling a prescription for a schedule II substance shall, if requested by the patient, dispense the prescribed substance in a lesser quantity than indicated on the prescription."
The mechanics carry two distinct clocks, and telling them apart is the exam point:
| Step | Deadline |
|---|---|
| Initial partial dispensing must occur | within 5 days after the prescription issue date |
| Remaining portion may be dispensed | within 30 days after the prescription issue date |
[!CAUTION] Do not merge the two clocks. A common wrong answer says the patient simply has 30 days. In Massachusetts the first partial fill must happen inside 5 days of issuance; only then does the 30-day window for the balance apply. And because c. 94C, § 23 independently invalidates a Schedule II prescription 30 days after issuance, the outer boundary is the same 30 days either way.
Documentation for each partial fill records the date, the quantity dispensed, the quantity remaining, and the identity of the dispensing pharmacist. The aggregate across all partial fills may never exceed the quantity prescribed.
Federal partial fill provisions still apply
- CARA (2016) permits a partial fill of a Schedule II prescription at the request of the patient or the prescriber.
- 21 CFR 1306.13 permits partial filling for a patient in a long-term care facility or a patient with a terminal illness, with the prescription valid for up to 60 days from issuance, and requires the pharmacist to record "LTCF patient" or "terminally ill" on the prescription.
- Where a pharmacy cannot supply the full quantity, the remaining portion may be supplied within 72 hours; if it cannot be, the pharmacist must notify the prescriber and no further quantity may be supplied without a new prescription.
Where the state and federal windows differ, apply the stricter one to a Massachusetts prescription.
Related Public-Health Duties
Massachusetts wraps several counselling and information duties around opioid dispensing. The pharmacist should be prepared to discuss safe storage, safe disposal, the availability of naloxone (see section 8.2), and the option of requesting a partial fill — the last being the practical purpose of the § 18 right.
Worked Traps
- A 16-year-old with a fractured ankle is prescribed a 10-day supply of oxycodone. Violation of § 19D regardless of clinical justification — the minor cap is absolute at 7 days.
- An adult with metastatic cancer receives a 30-day supply on a first opioid prescription. Permitted; cancer-related pain is a listed exception, with documentation in the medical record.
- A patient asks for only 10 of 30 tablets on a Schedule II prescription issued six days ago. The initial partial dispensing window of 5 days after the issue date has passed; the pharmacist should contact the prescriber rather than attempt a partial fill under § 18.
- An adult is prescribed a 14-day supply of buprenorphine for opioid use disorder. Outside § 19D entirely — the limits do not apply to medication for the treatment of substance abuse or opioid dependence.
Which statute imposes the Massachusetts 7-day opiate supply limits?
A 15-year-old patient has been receiving opioid analgesia for three weeks following major surgery. The surgeon writes a further prescription for a 10-day supply. What does M.G.L. c. 94C, § 19D permit?
A Massachusetts patient asks to receive only part of a Schedule II prescription. Under M.G.L. c. 94C, § 18, what timing rules govern the partial fill?
