Home Health Billing in 2026: What's Changed

Home health billing isn't getting easier. Between PDGM's clinical grouping logic, Remote Access Protocol requirements, and payer-specific documentation hurdles, practices are leaving real money on the table — often without knowing it.

If you're working through these issues, our specialty billing services can help you address them systematically.

What PDGM Actually Means for Your Revenue

The Patient-Driven Groupings Model has been live since 2020, but agencies are still making costly mistakes. PDGM splits every 30-day period into one of 432 payment groups based on admission source, timing, clinical grouping, and functional impairment level. Get one of those wrong, and you're underpaid. Sometimes by a lot.

The biggest slip-ups? Timing category errors — when a period should be coded "early" but gets submitted as "late." That alone can reduce your payment by 10–15% on a claim.

Quick check: Are your coders confirming OASIS M-codes before finalizing the clinical grouping? If not, that's worth fixing this week.

RAP Submissions and the No-Pay RAP Rule

CMS moved home health agencies to a no-pay RAP model. Agencies that submit RAPs late face a payment reduction — and some are still treating RAPs as optional housekeeping. They're not. Submitting within five days of the start of care keeps your cash flow intact.

Miss that window? You lose a percentage of your episode payment for every day you're late. It adds up faster than you'd expect.

The Three Denial Patterns We See Most

1. Homebound Status Documentation

Every payer wants proof the patient qualifies as homebound. That means documenting the specific reason leaving home is a considerable effort — not just checking a box. Vague language like "patient is frail" won't hold up on appeal.

2. Skilled Need Not Justified

Payers are pulling claims where the nursing or therapy notes don't clearly establish why skilled care is medically necessary. Your therapists and nurses need to document the skilled nature of every visit, not just what they did.

3. Physician Orders Out of Sync

When the plan of care doesn't match the actual services billed, you're looking at a denial or a costly adjustment. Keep physician orders current and reconcile them against visit notes before billing.

Watch out: CMS has increased targeted probe and educate reviews for home health agencies in 2026. If your error rate is above 15%, you could be pulled into pre-payment review — which effectively freezes your cash flow.

Functional Levels and OASIS Accuracy

Your OASIS assessor sets the functional impairment level, which directly affects which payment group you land in. There are three levels — low, medium, high — and the difference between medium and high can be $200–$400 per 30-day period. Worth getting right.

One thing that helps: having a dedicated OASIS review step before claims go out. Agencies that build this into their workflow catch grouping errors before they become underpayments.

Therapy Threshold Changes

Under PDGM, therapy visit thresholds no longer drive payment — but therapy documentation still matters enormously for justifying skilled need. Don't let your PT and OT staff get sloppy with notes just because the therapy threshold rule is gone. Payers still audit those visit records aggressively.

Tip: Build a monthly PDGM audit into your billing workflow. Pull a random sample of 30-day periods, check grouping accuracy, and track your denial rate by clinical group. You'll find patterns fast.

Telehealth and Remote Monitoring

CMS has expanded coverage for remote patient monitoring in home health for certain conditions. The billing codes are there, but the documentation requirements are strict — you need to show the data was actually used to inform clinical decisions, not just collected. A lot of agencies are missing the revenue here because they're not coding it at all.

What to Audit This Quarter

Home health billing rewards discipline. The agencies that get this right consistently aren't smarter — they just have tighter processes.
