Good morning.
PDPM didn’t get rebuilt. Here’s what changes today.
If somebody tells you today that “PDPM changed,” ask what they mean.
CMS did not rebuild the basic payment model.
But the coding tools and assessment instructions underneath it have changed.
That distinction matters.
You don’t need to become a reimbursement expert overnight.
You do need to know whether your team is ready.
This is about PDPM classification and MDS documentation—not every FY 2027 payment-rate or quality-program change.
What actually changes today?
For MDS assessments with target dates on or after October 1, CMS’s updated PDPM grouper uses the FY 2027 ICD-10 code set and updated diagnosis mappings.
The October 2026 RAI Manual also takes effect, with updated instructions involving areas such as cognitive and mood interviews, wounds, isolation and respiratory therapy.
Your software needs to be current.
Your team needs to understand the instructions that affect its work.
But “Medicare changed” should not become shorthand for:
“Everybody write longer notes.”
That’s how we create 14-paragraph nursing notes nobody wants to read.
The better message:
Document specifically enough that another person can understand the resident’s needs, the care provided and the assessment decisions.
Three checks I’d make today
1. Ask MDS to confirm the software update.
Not “the vendor usually handles it.”
Ask to see the release confirmation or other evidence that your assessment software supports the October 1 updates.
2. Ask your DON and MDS coordinator what staff need to do differently.
Which updated instructions affect your residents?
Who needs that guidance?
How will you know they understood it?
Targeted instruction beats an all-staff announcement that “documentation needs to improve.”
3. Trace one recent Medicare admission at your next Medicare meeting.
Follow the resident from the hospital record through nursing, therapy, MDS and billing.
Where does the clinical story become unclear?
Who owns the missing piece?
By when will it be resolved?
Because that’s where an administrator can make a real difference.
Before admission: Why are they coming?
What condition is driving the skilled stay?
What other active conditions and services matter?
Your team should have a clear, supported explanation—not a convenient diagnosis substituted for a more specific condition documented by the practitioner.
Operator lesson: Your MDS nurse shouldn’t be figuring out on Day 5 why the resident was admitted.
Days 1–3: What can the resident actually do?
Section GG admission performance uses the first three calendar days of the Part A stay.
It should reflect the resident’s usual baseline performance under the assessment instructions.
Different observations can be legitimate.
A resident may perform differently at different times or under different conditions.
The job is to understand and reconcile those differences—not force nursing and therapy notes to match.
The 5-Day MDS: Does the assessment fit the resident?
The assessment reference date falls within Days 1–8.
That is not a universal eight-day look-back or the deadline for completing every assessment task.
Each item has its own instructions.
PDPM has five case-mix components: PT, OT, speech-language pathology, nursing and non-therapy ancillary.
You don’t need to memorize every classification rule.
You do need to make sure the resident’s relevant conditions, function and services aren’t buried on page 173 of the hospital record.
STEAL THIS: THE MEDICARE RESIDENT JOURNEY
I built a one-page PDPM Operator 101 that follows the resident from referral through discharge.
At each step, it gives you:
Who owns the work.
What needs to happen.
What evidence to ask to see.
Take it to your next Medicare meeting and ask:
“Where in this journey are we most likely to lose the resident’s clinical story?”
Then assign one gap to one person with a due date.
A resident comes through your front door with a clinical story.
Admissions sees part of it.
Nursing sees part.
Therapy sees part.
The practitioner documents part.
MDS translates it.
Billing gets the result.
Your job as the operator is making sure those pieces tell the same story.
Accurate documentation supports correct reimbursement.
It also helps the next person understand what care the resident needs.
That’s the part I’d make sure my team understands today.
