Key facts
Timeline
CMS reported more than 150 organizations accepted as of August 17, 2026, most of which “have not previously served Medicare beneficiaries.”1
Participant eligibility
From the RFA’s Participant Eligibility Criteria, a participant must:2- “Be a Medicare Part B–enrolled organizational entity, identifiable by a single TIN, that is eligible to bill under the Medicare Physician Fee Schedule (PFS).” Participation is “defined at the organizational TIN level, not the individual practitioner level.”
- “Be a legal entity formed under applicable state, federal, or Tribal law, and authorized to conduct business in each state in which it operates.”
- “Maintain active Medicare Part B enrollment under a single TIN.”
- “Designate and maintain a Medicare-enrolled physician as Medical Director, responsible for oversight of care delivery and model performance.” The Medical Director must be an MD or DO who is an employee of, or under contract with, the participant; the participant may contract with a self-employed physician or “a physician employed by a professional entity or physicians’ group.” (The model page and FAQs call this role the “physician Clinical Director.”)
- “Ensure that all physicians and non-physician practitioners furnishing or supervising care are individually Medicare-enrolled, participating providers or suppliers who have reassigned their Medicare billing rights to the participating TIN and practicing within applicable licensure and scope-of-practice standards.”
- Maintain a current roster of Medicare-enrolled practitioners, with NPIs, furnishing or supervising care under the TIN.
- Complete CMS program integrity screening under 42 C.F.R. Part 424.
Tracks and outcome measures
Participants must manage all qualifying conditions within a track. CMS may add tracks in later years. Track-specific exclusions apply: for example, ESRD dialysis patients in CKM/eCKM and CCBHC enrollees in BH.4
Payment
Outcome-Aligned Payments (OAPs) are flat, per-beneficiary annual allowed amounts per track, not per condition, with a higher Initial Period (12 months) and a lower Follow-On Period. Amounts effective July 5, 2026 through December 31, 2027 (allowed amount = 80% Medicare plus 20% coinsurance):5
A $15 rural add-on applies to the eCKM and CKM initial period. A 5% multi-track discount applies to the lower-cost track where a beneficiary is in more than one.
Mechanics. Participants submit monthly claims with track-specific G-codes to their MAC; the claims process as zero-paid and the Innovation Payment Contractor pays. Monthly payments equal one-twelfth of the Medicare portion and are capped at 50% of the annual amount; the remaining 50% is withheld and reconciled after the 12-month care period through two adjustments:
- Clinical Outcome Adjustment: based on the share of aligned beneficiaries meeting outcome targets against an Outcome Attainment Threshold of 50% for the first 18 months; the reduction is capped at 50% of the OAP.
- Substitute Spend Adjustment: reduces payment for duplicative fee-for-service spending on the same condition. Participants and financially affiliated entities certify they will not bill FFS for aligned beneficiaries’ track conditions during the care period.
Waivers and flexibilities
Under § 1115A, CMS waives the MIPS provisions and the Part B payment-percentage rule for OAPs, pays outside FFS, withholds payment on outcomes, and grants “program waivers as needed to … allow for services to be provided via telehealth, asynchronously, and/or directly through the applicable technology.” Participants who forgo OAP cost-sharing rely on the CMS-sponsored model patient incentive safe harbor at 42 C.F.R. § 1001.952(ii)(2); if they collect cost-sharing they must disclose the expected amount before enrollment and apply it uniformly. Devices may be furnished on loan or for keeps consistent with the beneficiary engagement incentive rules. Waivers end on termination; withdrawal requires 180 days’ notice.2Health IT requirements
