July 1, 2025 All-Payer OASIS Rollout: What Your Agency Needs to Know (Without the Confusion)

There’s been a lot of buzz—and confusion—about the July 1, 2025, All-Payer OASIS rollout. Many agencies are unsure if it applies to them, especially those providing non-skilled services.

Let’s clear things up.

First, What Is the All-Payer OASIS Rollout?

Starting July 1, 2025, all Medicare-certified Home Health Agencies (HHAs) must collect and submit OASIS data on all adult skilled patients, regardless of the payer source.

That means whether the patient is covered by:

• Medicare Advantage
• Medicaid
• Commercial insurance
• Self-pay
• Charity care

OASIS will be required if they’re receiving skilled care from a Medicare-certified HHA.

Does This Apply to Non-Skilled Home Care Agencies?

No.

If your agency only provides non-skilled services—like personal care, companionship, or housekeeping—and you are not Medicare-certified, this rule does not apply to you.

You do not need to start collecting or submitting OASIS.

Who Is Exempt from OASIS (Even After July 1)?

Even if you’re a Medicare-certified HHA, the following patients remain exempt:

1. Patients under 18 years old
2. Maternity patients (receiving care for pregnancy or postpartum conditions)
3. Patients receiving only non-skilled services (like personal care or homemaking)
4. Patients seen only by a social worker or home health aide
5. Patients who were referred but never admitted

What Should Medicare-Certified Agencies Do?

If you’re a Medicare-certified home health agency, make sure your clinical and intake teams know:

• Starting July 1, OASIS applies to all skilled adult patients, regardless of insurance.
• Train your staff to identify who is exempt (see list above).
• Double-check that your documentation and systems are ready to support OASIS data collection across all payer types.

Still Not Sure?

If you’re unsure whether this applies to your agency, ask yourself:

“Are we Medicare-certified, and do we provide skilled care?”

If the answer is yes, this rollout applies to you.

If not, breathe easy. This rollout does not affect non-skilled, non-Medicare-certified home care providers. SimiTree can help your agency stay ahead of the All-Payer OASIS rollout with customized training, compliance reviews, and OASIS documentation support. Contact us to get started.
