Honest Medical Group - Providers Intro Image

For ACO REACH, we help build networks of Preferred Providers that encompass specialists and other healthcare providers who not only understand but support the importance of coordinated high quality care. These providers have agreed to voluntarily collaborate in coordinating care, exchanging data and information, and adhering to evidence-based practices to improve care quality while lowering costs.

We value the crucial role played by preferred providers in delivering care. By electing to be a part of the preferred provider network, together we can achieve quantifiable enhancements in patient outcomes and elevate the quality of care for our patients.

Frequently Asked Questions

What is ACO REACH and does this impact all Medicare beneficiaries?

In an effort to drive health system transformation and achieve equitable outcomes through high-quality, affordable, person-centered care for all patients in Traditional Medicare, the Centers for Medicare & Medicaid Services (CMS) introduced the ACO REACH model, the successor to the Global and Professional Direct Contracting Model (GPDC), in early 2022.

Beneficiaries with Traditional Medicare retain all of their rights, coverage, and benefits, including the freedom to see any Medicare provider. Like previous ACO models, the ACO REACH Model prohibits limited networks, prior authorization or any other means of restricting care. CMS expects that beneficiaries with providers participating in ACO REACH will benefit from improvements in quality of care, enhanced services, like telehealth, home visits after leaving the hospital, cost sharing support, and greater access for underserved communities, reaching beneficiaries who have not previously received coordinated care.

I participate in an ACO. Does this mean I am already in ACO REACH?

No, not all ACOs are participating in the ACO REACH model. The good news is that even if your ACO doesn’t participate in ACO REACH, as a Preferred Provider you can participate with more than one ACO REACH entity.

Which Medicare beneficiaries qualify?

To qualify as a potential ACO REACH entity aligned beneficiary, Medicare beneficiaries must meet all of the following criteria:

  • Enrolled in Medicare Parts A & B
  • Not enrolled in Medicare Advantage plan or with another payer such that Medicare is the beneficiary’s secondary payer
  • Resident of the United States
  • Resident of a county that is included in the ACO REACH service area.

Beneficiaries that meet the above criteria are assessed by CMS using ACO REACH’s attribution methodology.

What is patient attribution and how does it work?

Attribution may also be referred to as assignment or alignment and is the methodology used by CMS to identify the beneficiaries associated with an ACO REACH entity.

Medicare beneficiaries are aligned to each ACO REACH entity based on:

Claims Attribution - CMS attribution model that identifies patients with a plurality of claims submitted by Participant providers

Voluntary Alignment - The patient voluntarily chooses to become an aligned patient

How does the fee reduction work?

The fee reduction specified in the PP contract will solely be applicable to ACO REACH beneficiaries associated with the contracting ACO entity of the PP.

The ACO entity will furnish the provider roster and fee reduction information to CMS through the 4i reporting system, which will then share the data with the local MAC (Medicare Administrative Contractor )(MAC).

Subsequently, the MAC will apply the discount to all Fee-for-Service (FFS) claims submitted by the practice, utilizing the provider roster and fee reduction data provided by the ACO entity, and the ACO entity’s list of attributed Medicare beneficiaries.
