The Addendum Is No Longer on Request. It's Every Admission.

An admissions nurse sits at her desk with the referral packet in front of her. She is working out which of the patient's medications hospice will cover and why. Some are clearly for the terminal illness. Others were started years ago by another doctor for another problem, and whether hospice is responsible for them is a judgment she has to make one drug at a time.

She has made this call a hundred times. What changed is that when a hospice determines a medication isn't covered, the decision must be documented and provided to the patient's family. Starting October 1st, the hospice team has five days from hospice election to provide this information.

What actually changed

None of this is a brand-new requirement. The Patient Notification of Hospice Non-Covered Items, Services, and Drugs has existed for years, but a hospice only had to produce it if a family asked, and almost none did. The FY 2027 final rule removes the need for a request. Now every election gets one, whether asked for or not.

The most visible change is volume. A hospice that once produced a handful of these a year now produces one for every patient it admits. The volume is the easier problem to solve, while the real difficulty lies in the detail and knowledge required for each document.

For every medication hospice will not cover, the addendum has to say, in language a family can read, why that drug is unrelated to the terminal illness. A diagnostic code or a one-word "unrelated" does not meet that bar, and it will not hold up under the new scrutiny these determinations now face. In one study of patients with a prognosis under a year, patients averaged 11.5 medications at enrollment, most of them the kind a reasonable clinician could defend either way, one drug at a time.

The reasoning behind those calls has never lived in one place. It sits in a physician's judgment, a conversation at the IDG table, an email thread, and a formulary that records what is covered without recording why. Producing a written explanation out of that, on a clock, at every admission, is the real work the rule just created.

A document is a commitment

Until now the relatedness determination was private and provisional. It got made at admission, revisited as the patient's picture came into focus, and quietly corrected as the team learned more. Nobody outside the hospice watched it move.

From October 1st, the first version goes on paper and into a family's hands within five days. While the rule provides a path to revise a determination, by updating the addendum within three days of a change to the plan of care, the conversation with a family who already has the original in writing is far more difficult than the update itself.

Moving a medication from uncovered to covered is a phone call nobody minds making. Moving one the other way costs trust, and it now leaves a visible trail across two documents and a medical record. The accuracy of the first determination carries weight it never had to carry before.

Why being proactive matters

A hospice has five days from the election to provide the addendum, which sounds like a reasonable amount of time until you count what else those five days have to hold. The patient is admitted, orders are going out, and anything the team discovers late is something additional that must be documented.

That same window already holds another requirement. The conditions of participation require the interdisciplinary group, in consultation with the attending physician, to complete the comprehensive assessment within five calendar days of the election, and that assessment has to include a drug profile covering effectiveness, side effects, interactions, and duplicate therapy. Many hospices also run a pharmacist medication review, which the regulation does not require but long practice has made standard.

The review that would sharpen the determination and the document that commits it now fall on the same clock. Because they run in parallel rather than in sequence, what the review determines arrives alongside the addendum instead of ahead of it.

The hospice team that takes a proactive approach and is able to complete the documentation prior to admission sets themselves up for success in the race against the clock and for the family's satisfaction. That matters more than it used to, because every correction now leaves a visible trail and costs something with a family. A first pass that holds up is worth far more than one the team expects to fix later.

What answering the addendum takes

Every medication the hospice will not cover raises the same short list of questions, and the addendum is only as good as the hospice's ability to answer them.

Answering these after the pharmacy has already rejected a claim is too late. By then the determination is written and the family has already been told. The real measure of whoever supports your pharmacy benefit is whether they can put these answers in front of the team while the answer can still change what goes on the page.

What this looks like with MerlinRx

MerlinRx is built to answer those questions before a commitment is made rather than after one fails.

Pre-admission tools let a team work through an incoming medication list while the plan can still change, before anything has to be walked back. The conversation with the physician happens over a profile that already shows where the friction is, rather than over a list that looks fine until it reaches a pharmacy.

The effect at the counter is the part that matters. A claim that would have rejected on a Tuesday and turned into a Wednesday of phone calls never rejects, because the coverage question was answered before it ever went out. The family is told something accurate the first time, and it stays accurate.

The determination you write down

Most of what the addendum asks for is work good hospices were already doing. What changes is that the work now produces a document, on a clock, that a family will hold on to.

The hospices that excel at this will be the ones that had the tools to answer these questions before admission, not the ones making retroactive corrections within the five-day window. Precision on the first pass stops being a nicety and becomes the whole job.
