Early refills, vacation overrides and emergency supplies

From April 2023 through October 2024, New York's Medicaid program paid about $585.2 million on more than 3.6 million pharmacy claims for drugs and supplies refilled earlier than its own policy allowed, the state comptroller reported in March 2026¹. Nearly 43 percent of the claims the auditors flagged had 20 or more days of excess supply. In one case, a single member received 36 fills of the same drug in about 15 months, leaving 280 days' supply on hand at the last fill.

New York's rule is typical of how drug plans police timing. According to the state's Medicaid pharmacy manual, as quoted in the audit, a refill is paid when more than 75 percent of the previous supply has been used, or when up to a 10-day supply remains of everything dispensed over the previous 90 days, whichever is stricter.

Every drug plan runs some version of that check, usually called a refill-too-soon edit. It is the reason a pharmacy may say a refill cannot go through before a trip, after a lost bottle, or when a dose has changed. This piece explains how the edits work, the overrides plans use for vacations and lost medicine, the federal guidance for disasters, and the state laws that let pharmacists give an emergency supply when no refill is available.

How a refill-too-soon edit works

The check happens in the seconds after a pharmacy submits a claim. If the plan's records show too much of the last fill should still be on hand, the claim comes back rejected. In the industry's standard claim format, that rejection is usually reject code 88, a drug utilization review error, with the reason code ER for overutilization, as both New York Medicaid² and California's Medi-Cal Rx³ describe it to pharmacies.

Plans set their own thresholds. For Medicaid, federal rules require some form of the check: 42 CFR 456.705⁴ says a state must review drug therapy before each prescription is filled, screening for problems that include clinical abuse and misuse, and 42 CFR 456.703(h)⁵ requires states to set prospective safety edits on early refills of opioids. The percentage is left to each state or its contractors, and commercial plans and Medicare drug plans set their own. The table shows what common thresholds mean in days, using simple arithmetic.

GxRadar calculation. Plans count partial days, dose changes and prior fills in different ways, so the exact first eligible date varies.

California tightened its policy this year. Starting Aug. 21, 2026, Medi-Cal Rx began applying early-refill override limits to members 21 and older when a refill comes at less than 75 percent of the previous fill's interval, or less than 90 percent for opioids, according to a July 2026 notice to pharmacies³. Members younger than 21 were not affected "at this time," the notice said.

Vacation and lost-supply overrides

When a refill is genuinely needed early, the pharmacy can resubmit the claim with a code explaining why. Medi-Cal Rx lists three: an overutilization override entered with professional service and result codes, submission clarification code 03 for a vacation supply, and code 04 for a lost supply. Under its 2026 policy, each override may be used once in a 365-day period. After that, claims deny with a message that early refill overrides are exceeded, and the pharmacy has to contact the program. New York Medicaid takes a stricter line. Its 2015 notice² says a claim carrying code 03 for a vacation supply or 04 for lost or stolen medicine will still deny, and that replacing lost or stolen medicine takes a prior authorization request from the prescriber, never granted for controlled substances.

Whether a plan accepts those codes, how often, and whether it wants a call from the patient or prescriber first is a plan decision. A traveler expecting to be away when a refill comes due can ask the plan what it allows, and ask the pharmacist which code, if any, applies. Some patients get the same effect by filling a longer supply, a choice with its own cost math covered in our pieces on 90-day fills and mail-order pharmacy. Plans can also limit quantities or require approval for some drugs, as described in our explainer on prior authorization and step therapy.

Disasters and declared emergencies

For Medicare drug plans, CMS has issued guidance on early refills during disasters. In an August 2017 memo⁶ issued during Hurricane Harvey, CMS said that in all disaster declarations Part D plans "are expected to lift their 'refill-too-soon' edits" and to let an affected enrollee obtain the maximum extended day supply, if requested and available. Plans may keep the edits off after a declaration ends, CMS said, and if they turn them back on they need to work with enrollees who are still displaced.

A March 2020 CMS memo⁷ on COVID-19 worded the same flexibility as permission: Part D plans "may relax their 'refill-too-soon' edits" when circumstances are reasonably expected to disrupt access, even ahead of an impending disaster. Separately, 42 CFR 423.124(a)⁸ requires Part D plans to ensure access at out-of-network pharmacies when an enrollee cannot reasonably be expected to use a network pharmacy, which matters when the usual store is closed.

Some states write the same idea into insurance law. Florida Statutes 252.358⁹ requires health insurers and HMOs licensed by the state's Office of Insurance Regulation to waive refill time limits, including "suspension of electronic 'refill too soon' edits," and to pay for at least a 30-day supply when the patient lives in a county under a hurricane warning, a governor's emergency declaration, or an activated county emergency operations center and emergency management plan. The refill has to be requested within 30 days of those conditions starting, and there must be refills left on the prescription. The law reaches insurers and other entities licensed by the Office of Insurance Regulation; a patient unsure whether a plan is one of them can ask the plan.

Emergency supplies when there is no refill

A different problem arises when a prescription has run out of refills and the prescriber cannot be reached. (Moving a prescription that still has refills is simpler, as our guide to transferring a prescription explains.) Some states, including Florida and Ohio, let a pharmacist dispense a short supply on professional judgment, and their laws show how specific the rules are.

Florida Statutes 465.0275¹⁰ allows a one-time emergency refill of up to a 72-hour supply. For insulin and related diabetes supplies, it allows up to three nonconsecutive emergency refills per calendar year. When the governor declares a state of emergency, pharmacists in the affected counties may dispense up to a 30-day supply of a drug that is "essential to the maintenance of life or to the continuation of therapy in a chronic condition," excluding Schedule II drugs, and must notify the prescriber.

Ohio Revised Code 4729.281¹¹ lets a pharmacist dispense once, up to a 72-hour supply, when the drug is essential and going without it could cause harm. For a non-controlled drug the patient has taken consistently, the pharmacist may dispense up to three times in 12 months, not consecutively. The first may be up to a 30-day supply and later ones up to seven days. Schedule II drugs are excluded.

These laws govern what a pharmacist may dispense. They do not say what a plan will pay, and a plan's refill-too-soon edit can still apply. Questions about medicine running short during a drug shortage are a separate matter, covered in our guide on what to ask when a medicine is in shortage.

New York's comptroller recommended that the state Health Department conduct a risk-based review of the $585.2 million in early-refill payments, recover money where appropriate, and strengthen its claim edits. In California, Medi-Cal Rx said it would provide more information later about any change for members under 21.
