When Your Plan Changes: What to Check First
A new plan year, a new job, or a plan rebuilt around you all produce the same risk — an approval that no longer applies and nobody noticing until a claim rejects. The check takes an hour and it belongs before the change, not after.
Key takeaways
- An approval belongs to the plan that granted it and does not travel on its own — including across a plan year with the same card.
- Pull four documents in order: the new drug list, the exclusions section, the criteria behind any notation, and your current approval letter.
- Ask the new plan separate, specific questions and log each answer with a date, a name and a reference number.
- Transition arrangements for established patients often exist but generally have to be requested, and they carry their own timing conditions.
- Across a job change, find the exact end date and effective date — those two define the exposure, and supply questions must be asked before the first one.
- Three dates drive everything: approval expiry, plan start, and any transition deadline. Set reminders sized for appointment lead time.
Answer first: a prior approval does not travel on its own
An approval belongs to the plan that granted it, under the rules that plan had at the time. When the plan changes, the approval does not automatically follow.
That is true across a job change, and it can be true across a plan year with the same employer and the same card. The card looking identical is not evidence that anything underneath it held.
So the check is the same in every version of this. Establish what the new arrangement says about your medication, and whether a fresh request is needed, before the old arrangement stops.
Nothing here describes what any named plan does or what any deadline is. The notices you receive and your plan documents are what govern, and the point of this guide is to tell you which of them to open first.
The three changes that look the same and are not
A plan year turnover keeps your employer and often your card, and rebuilds the rules. Drug lists, tiers, criteria and cost sharing can all be reissued at once.
A change of employer or of plan replaces the whole arrangement. New drug list, new criteria, new deductible, and generally no knowledge of anything approved before.
A mid-year change is the one people do not expect. Plans can revise drug lists and criteria during a year, and an employer can change administrators without changing anything a member would notice on the card.
All three end the same way if nobody checks: a claim rejects at a counter, and a renewal that could have been filed in advance now has to be filed under pressure.
The four documents to pull, in order
Start with the new plan's drug list, and look up the exact drug and form you are prescribed rather than the ingredient. Note the tier and every notation beside it.
Then the exclusions section of the new plan documents, read at the category level. This is where a category-wide decision is normally written, and it is usually not on the drug list.
Then the criteria document behind any notation you found, because that is what a new request will actually be judged against. Ask for the continuation criteria as well as the initial ones, since they are frequently separate.
Then your own current approval letter, for its end date and its conditions. Comparing the old conditions against the new criteria is what tells you how much work the transition is.
The question to ask the new plan, worded so it gets answered
Vague questions get vague answers here, and a vague answer is worse than none because it feels like information.
Ask whether the plan will honor an existing approval from a previous plan, and if so what it needs to see. Ask whether a new prior authorization is required for the specific drug and form, and whether continuation criteria apply or initial ones. Ask whether any transition arrangement exists for someone already established on a medication.
Ask each of those as a separate question and write down each answer with the date, the representative's name and a reference number. A single summarized note is not much use two months later.
Where coverage comes through an employer, ask the benefits team the same set. They frequently know things about the specific group's arrangement that a general service line does not.
Transition arrangements exist, and they are not automatic
Many plans have some mechanism for people already established on a medication when the rules change. What it is called, how long it runs and what it requires all vary.
The important part is that these arrangements generally have to be requested, or at least triggered, and they usually have their own timing conditions. Waiting to see what happens at the pharmacy is the reliable way to miss one.
Ask specifically whether one exists for your situation, and ask what has to happen to use it. A pharmacy can often tell you quickly whether one is applying to a claim, which makes the counter a useful diagnostic even when it is not the place to solve the problem.
Treat any such arrangement as runway rather than as a solution. It buys time to complete a proper request, and the request still has to be completed.
Gaps between plans
A change of employer can leave a period with no coverage, or with coverage that has not begun processing yet. Prescriptions do not pause for that.
Find out the exact date the old coverage ends and the exact date the new coverage becomes effective, and note whether the new plan applies retroactively to its start date. Those two dates define the exposure.
Where a gap exists, the practical questions are about supply rather than about paperwork. Ask the prescribing office and the pharmacy what is possible before the end date, since the options narrow considerably once it passes.
Any continuation of previous coverage that may be available to you is described in the notices you receive when coverage ends. Read those when they arrive rather than filing them, because they generally carry their own deadlines.
Rebuild the file for the new plan
The documentation that satisfied the old plan's criteria may not map onto the new plan's. Different criteria ask for different evidence, and a packet built for one is not automatically a packet for the other.
Read the new criteria first, then work out what you already have and what is missing. Records held by practices you have left are the usual gap, and releases take time, so start those early.
Give the prescribing office the new criteria document rather than only the news that the plan changed. An office working from the actual criteria can build the right request the first time.
Then start a fresh file for the new plan: the new drug list with its date, the criteria, the new approval letter when it arrives, and every call logged. The old file stays, because it is the evidence of what was approved before.
The calendar this all hangs on
Three dates decide most of this, and none of them are hard to find once you look.
The date your current approval ends. The date the new plan year or the new plan begins. And the date any transition arrangement or continuation option expires.
Put all three on a calendar with reminders set well ahead, sized for how long it takes to get an appointment rather than how long it takes to send a form.
Almost every bad outcome in this category is a calendar failure wearing the costume of a coverage dispute. The hour spent on the documents in advance is the cheapest hour available.
Frequently asked questions
I changed jobs. Does my prior authorization carry over?
Generally not on its own. An approval belongs to the plan that granted it, under that plan's rules, and a new plan usually has no knowledge of it. Ask the new plan directly whether it will honor an existing approval and what it would need to see, since some plans have a mechanism for people already established on a medication. Ask as a specific question rather than a general one, and write down the answer with the date, the name and a reference number. Then plan for a fresh request, because that is the more common outcome.
My card looks the same. Can anything really have changed?
Yes, and this is one of the most common surprises in this category. A plan year turnover can reissue the drug list, move tiers, rewrite criteria and restructure cost sharing while the card and the employer stay the same. Plans can also revise drug lists and criteria mid-year, and an employer can change administrators without anything on the card changing. The card identifies where a claim is sent; it says nothing about the rules being applied when it arrives.
What should I look up first when a plan changes?
Four documents, in this order. The new plan's drug list, looking up the exact drug and form rather than the ingredient, noting the tier and every notation. The exclusions section of the new plan documents, read at the category level, since that is where category-wide decisions are written. The criteria document behind any notation, including continuation criteria if they are separate. And your existing approval letter, for its end date and conditions. Comparing the last two tells you how much work the transition actually is.
Is there anything that protects me while the new plan reviews a request?
Many plans have some arrangement for people already established on a medication when rules change, though what it is called, how long it lasts and what it requires all vary. These generally have to be requested or triggered rather than applying automatically, and they usually carry their own timing conditions. Ask the new plan whether one exists for your situation and what has to happen to use it. Treat it as runway to complete a proper request, not as a substitute for one.
There will be a gap between my old and new coverage. What do I do?
Establish the two dates first — when the old coverage ends and when the new coverage becomes effective — and find out whether the new plan applies retroactively to its start date. Those define the exposure. Where a real gap exists, the useful questions are about supply and are best asked of the prescribing office and the pharmacy before the end date, because the options narrow once it passes. Any continuation option available to you is described in the notices sent when coverage ends, and those carry their own deadlines.
Can I reuse the packet that got me approved before?
Read the new criteria before assuming so. Different plans ask for different evidence, and a packet built to satisfy one set of criteria is not automatically responsive to another. Work out what the new criteria ask for, what you already hold, and what is missing — records from practices you have left are the usual gap, and releases take time to process. Giving the prescribing office the actual criteria document, rather than just the news that the plan changed, is what lets them build the right request the first time.
