The Patient-Driven Groupings Model (PDGM) replaced the Pre-OASIS Prospective Payment System for home health in January 2020. Five years in, many Florida agencies are still leaving money on the table — not from outright denials, but from incorrect episode classification that silently reduces reimbursement on every single claim.
How PDGM Classification Works
Every PDGM episode is a 30-day payment period classified across four dimensions simultaneously: referral source (community vs institutional), timing (early vs late), clinical grouping (one of 12 clinical categories), and functional level (low, medium, or high). The combination of these four variables determines the base payment rate for that period.
Florida agencies commonly misclassify episodes on the referral source dimension. An admission from a hospital-based SNF is institutional. An admission following a physician office visit is community. Getting this wrong changes the payment weight — and it happens on paper, before a single visit is made.
The Most Expensive PDGM Mistakes in Florida
- ✓Incorrect referral source coding — the most common and most costly error. Always verify the source of the written order, not just the physician signature.
- ✓Failing to reconcile OASIS scoring against clinical documentation before submission. Inconsistencies trigger ADRs that delay payment by 30–90 days.
- ✓Missing the LUPA threshold. Patients with fewer than the minimum required visits per 30-day period trigger a Low Utilization Payment Adjustment — essentially a per-visit rate instead of the full episode payment. Monitor visit counts in real time.
- ✓Not updating diagnoses from the referral. The primary diagnosis drives clinical grouping. If the referring physician lists a vague code, the agency must code from the full clinical picture — not copy the referral.
- ✓Submitting the RAP late. Florida agencies that miss the RAP window for Medicare face a 1/30th daily reduction for each day late.
LUPA Thresholds by Clinical Group — Florida Reference
LUPA thresholds vary by PDGM clinical group. Musculoskeletal Rehabilitation requires 3 visits minimum. Behavioral Health requires 2. Complex Nursing Interventions requires 4. Medication Management, Teaching & Assessment requires 3. Wound Care requires 3. Always verify current thresholds against the most recent CMS PDGM fact sheet, as they are updated with each rate notice.
Florida-specific: Medicaid managed care plans (Sunshine, Humana, Molina, Simply) do not use PDGM. They use their own fee schedules and episode definitions. Florida agencies billing both Medicare and MMC need separate billing tracks.
RAP Submission Requirements for Florida Medicare
The Request for Anticipated Payment must be submitted within 5 days of the start of care for timely payment. Late RAPs trigger the daily reduction penalty. Florida agencies with a history of late RAPs should audit their intake-to-claim workflow — the bottleneck is usually at the OASIS completion stage, not the billing department.
Denial Prevention — The 5 Checks Before Every PDGM Submission
- ✓Referral source documented in the clinical record — not assumed from the order
- ✓Primary diagnosis matches OASIS M1021 and drives the correct clinical group
- ✓Visit count meets or exceeds the LUPA threshold for the clinical group
- ✓OASIS score is consistent with all clinical notes in the episode
- ✓RAP submitted within 5 days of SOC — confirmed in your clearinghouse queue
