How CMS Restructured Primary Care: Proactive, Full-Visibility, and Reimbursable

If you practice primary care in the United States, two things happened over the last 36 months that probably did not show up in your inbox: the way CMS pays primary care got materially restructured, and the federal information-blocking rule moved from theoretical to enforced. Most clinicians missed both because the changes happened in regulatory channels that do not interrupt clinical work.

This article is an attempt to catch you up. It is written for clinicians, with citations to primary sources. It does not pitch a product. The implication at the end is that infrastructure now exists to align how you practice with how CMS reimburses, and where to read more if that is interesting.

The visibility gap most practices accept as normal

The typical primary care physician sees approximately 29% of a patient's medical history at a first visit. The other 71% lives in hospitals where the patient was admitted, prior practices the patient has since left, insurer claims databases, pharmacy systems, specialty consults that never made it back to the referring provider, and the patient's own memory. This is not a failure of any individual clinician. It is a structural property of how American medical records have ever been kept.

The consequences are documented. Duplicate testing rates run between 8% and 30% across studies. Drug interaction errors are the third-leading cause of preventable adverse drug events in ambulatory care. Diagnostic delays compound when each new clinician starts from a partial picture and re-derives a clinical impression others already reached.

Most clinicians know this. The question has never been whether full visibility would improve care. The question has been whether the infrastructure to deliver full visibility exists, who pays for it, and how to fit it into a 15-minute visit.

What changed in the plumbing (2021–2024)

The federal plumbing required to consolidate a patient's complete record has been quietly assembled over the last several years and is now operational. The major components:

HIPAA Right of Access (45 CFR § 164.524). Long-standing, but enforcement intensified after 2019. HHS Office for Civil Rights has now closed dozens of enforcement actions against providers and insurers for failing to provide records within 30 days, with settlements ranging from $3,500 to $4.3 million.

21st Century Cures Act, Public Law 114-255. Signed in 2016, with the Information Blocking Rule (45 CFR Part 171) effective April 2021. The rule prohibits any "practice that is likely to interfere with, prevent, or materially discourage access, exchange, or use of electronic health information" by covered actors. The list of actors includes healthcare providers, EHR developers, and health information exchanges. ONC overview here.

USCDI v3 and the expansion to all electronic health information. As of October 2022, the data set covered by the information blocking rule expanded from a limited core set to all electronic health information held by a covered actor. The practical effect: an authorized record-consolidation service can request and receive comprehensive clinical data from any covered entity, and refusal without a documented exception is a federal violation.

TEFCA (Trusted Exchange Framework and Common Agreement). Operationalized in 2024. TEFCA establishes a national-scale interoperability network through which a credentialed actor can query for a patient's records across the country with a single request, rather than chasing them institution by institution.

CMS Patient Access API. Health plans must, by rule, expose claims, encounter, formulary, and clinical data through a standardized FHIR API. This means an insurer's longitudinal view of the patient (every covered visit, every prescription, every billed test) is now machine-accessible.

Taken together, these changes mean that for the first time in US healthcare, the infrastructure to legally and electronically pull a comprehensive medical record across all of a patient's prior providers and insurers actually exists. It did not exist in 2018. It exists now.

Why CMS bet billions on proactive care

The plumbing alone would be interesting but irrelevant if reimbursement still rewarded only reactive, face-to-face care. The second restructuring is on the payment side. CMS has, over several Final Rules, made proactive care management substantially more lucrative than it was, and the 2026 Physician Fee Schedule is the most aggressive step yet.

The 2026 CMS Physician Fee Schedule Final Rule (CMS-1832-F) raised Chronic Care Management and Advanced Primary Care Management rates by approximately 8% to 11% across the board, depending on code. According to industry analysis of the rule, this is the largest single-year increase in care management reimbursement in five years.

The pattern is consistent across multiple CMS rules over the last decade. CMS has steadily moved primary care reimbursement away from fee-for-service face-to-face visits and toward longitudinal, between-visit coordination work. Star Ratings tie a meaningful percentage of Medicare Advantage plan revenue to quality measures that depend on closing care gaps. MIPS performance scores incorporate Promoting Interoperability measures. The Medicare Shared Savings Program and other ACO arrangements directly reward practices that demonstrate proactive coordination.

This is not a one-off rate adjustment. It is a multi-year regulatory consensus that the way Medicare pays primary care is shifting from "what did you do during the visit" to "how comprehensively are you managing this patient between visits."

The codes most practices don't fully capture

Most primary care practices are eligible to bill several care management code families. Capture rates across US primary care remain low, not because the codes are unavailable, but because the documentation prerequisites are operationally heavy. Here is the structure as of 2026:

Chronic Care Management (CCM)

For Medicare patients with two or more chronic conditions expected to last at least 12 months. The patient must consent and have an established relationship. The provider must develop and document a comprehensive care plan, and clinical staff must spend a minimum of 20 minutes per calendar month coordinating care outside face-to-face visits.

• 99490: First 20 minutes of clinical staff time per month. National average $66.30 in 2026.
• 99439: Each additional 20 minutes, billable up to 2 times per month. National average $50.56 each.
• 99487: Complex CCM, 60 minutes per month, moderate or high medical decision-making complexity. National average $144.
• 99489: Complex CCM add-on, each additional 30 minutes. National average $78. Billable unlimited times.

Advanced Primary Care Management (APCM)

Introduced 2025, refined for 2026. APCM is a bundled monthly payment that does not require time tracking. It is designed for practices that find CCM's minute-by-minute documentation burden a structural barrier.

• G0556: Level 1 APCM, patient with one chronic condition. Lower rate.
• G0557: Level 2 APCM, patient with two or more chronic conditions. National average $53.91 in 2026 (a 10.4% increase from 2025).
• G0558: Level 3 APCM, Qualified Medicare Beneficiary with multiple chronic conditions. Highest rate.
• G0568, G0569, G0570: New 2026 behavioral health integration add-on codes layered on top of APCM.

CCM and APCM are mutually exclusive for the same patient in the same calendar month. Practices select one or the other.

Principal Care Management (PCM)

For patients with a single complex chronic condition. An alternative to CCM when the patient does not have multiple chronic conditions but does have one that requires substantial management.

• 99424: First 30 minutes of physician or QHP time. National average $88.
• 99425: Each additional 30 minutes. National average $61. Unlimited add-ons.

Transitional Care Management (TCM)

For the 30-day period following a hospital, SNF, or partial hospitalization discharge. Requires interactive contact within 2 business days and a face-to-face visit within 7 or 14 days depending on complexity.

• 99495: Moderate complexity, face-to-face within 14 days. National average $220.
• 99496: High complexity, face-to-face within 7 days. National average $298.

Annual Wellness Visit (AWV)

Annual personalized prevention plan. Initial visit billable once per Medicare lifetime; subsequent visits annually thereafter.

• G0438: Initial AWV, national average $174.
• G0439: Subsequent AWV, national average $138 per year per Medicare patient.

Rates above are 2026 CMS national averages from the published Physician Fee Schedule. Actual payments vary by geography and locality conversion factor.

The economics, with real numbers

Capture-rate assumptions matter more than rate assumptions, because the rates are set. The question is how many eligible patients a practice actually enrolls and successfully bills each month.

Consider a hypothetical primary care practice with 600 Medicare-eligible patients. This is a modest panel for a single primary care physician. National benchmarks suggest the following conservative capture scenario:

• CCM at 50% capture (300 patients): 300 × $66.30 × 12 months = $238,680. With add-on time captured on 60% of patients at one additional 20-minute increment per month: an additional ~$110,000. Subtotal: roughly $167,000 in CCM-related revenue when conservatively modeled, or up to $349,000 with consistent add-on capture.
• AWV at 80% capture (480 patients): 480 × $138 = $66,240 per year.
• TCM at 25% panel-year discharge rate (150 events): 150 × ~$230 average = $34,500 per year.

Conservative total new annual recurring revenue for a 600-Medicare panel: approximately $268,000. The figure scales roughly linearly with panel size. A 300-Medicare panel captures approximately $134,000 at the same capture rates; a 1,200-Medicare panel approaches $536,000.

The provider time required for the CCM portion, at roughly 5 to 7 minutes of clinical review per patient per month, comes to approximately 30 to 40 provider hours per month across the 300 enrolled CCM patients. The CCM revenue alone divided by that time yields approximately $570 to $800 per provider-hour on incremental review work, a figure that compares favorably to most fee-for-service E/M codes on a per-minute basis.

AWV and TCM are not bonus revenue layered on top of CCM. They are standard E/M visits that get billed more completely when the provider walks into the visit with a consolidated record and identified gaps already documented. The figures assume those visits happen during normal clinic time, not as additional appointments.

The other half: Cures Act enforcement is no longer theoretical

The 2026 update is not just about the upside. Practices that block or impede patient and interprovider access to electronic health information are now facing real disincentives.

Enforcement against EHR developers and health information exchanges has been live since September 2023. The civil monetary penalty is up to $1 million per violation, with potential for stacking. The Information Blocking Complaint Portal received nearly 1,600 complaints by February 2026, per Holland & Knight's enforcement summary.

For healthcare providers specifically, disincentives took effect July 1, 2024. The structure ties information blocking findings to Medicare Promoting Interoperability scoring, MIPS performance, and ACO Shared Savings Program eligibility. A provider found to have committed information blocking can lose meaningful Medicare reimbursement through these channels. The legal authority is the July 2024 Final Rule on provider disincentives.

In February 2026, ASTP/ONC began issuing letters of nonconformity to specific EHR developers. The era of "the rule exists but no one enforces it" is over.

The practical implication for a primary care practice is twofold. First, requests for records from patients, from other providers, and from authorized third parties on the patient's behalf cannot be ignored, slow-walked, or refused without falling under one of the eight published exceptions. Second, infrastructure that helps the practice respond to such requests, consolidate the resulting data, and incorporate it into care now aligns with where federal policy is going, not against it.

Three paths for a primary care practice

A practice that wants to capture the reimbursement available and stay clean on Cures Act compliance has three structural options.

Build internally. Hire 1 to 2 FTE care coordinators per 500 enrolled patients. Train clinical staff on CCM documentation requirements. Implement gap-closure tracking in the EHR. License or build record-consolidation tooling. Establish workflows for HIPAA authorization capture at intake. Build a billing review process for monthly CCM claim submission. Realistic time to operational capability: 6 to 18 months. Realistic FTE cost: $80,000 to $200,000 per year depending on panel size. Realistic operational risk: high during ramp.

Wait. Defer the work. Continue to bill the standard E/M codes, capture no CCM or APCM revenue, and accept the increasing Medicare reimbursement penalty that comes from poor Promoting Interoperability scoring and missed value-based care quality bonuses. The cost is opportunity revenue plus erosion of MIPS performance. Patients who learn about the gap may move to practices that offer coordinated care.

Use an external service. Several services now exist that handle record consolidation, NP-signed care plan authoring, patient outreach, and closure documentation as a managed service. The better-structured services operate at no cost to the practice, are paid through value-based-care arrangements rather than billing the practice, and reduce the practice's involvement to clinical review and signature on the consolidated record. The practice remains the rendering provider and receives all CMS reimbursement directly.

This site, MyChartCount, maintains an introducer relationship with one such service. If that is interesting, the For Practices page covers the specifics of how the service works, what it costs, and what the practice's involvement looks like. The page exists because patients increasingly arrive at primary care visits asking why their records are scattered and what their practice plans to do about it.

Bottom line

Two things changed in primary care over the last three years that most clinicians do not yet operate by:

First, the federal infrastructure for record consolidation now legally exists. A complete patient record across all prior providers and insurers can be assembled, electronically, with the patient's authorization, in days rather than months. This was not possible in 2020. It is possible now.

Second, CMS reimbursement has been deliberately restructured to pay more for proactive, longitudinal, between-visit coordination, and to pay less to practices that do not engage with it. The 2026 Physician Fee Schedule is the most aggressive single-year shift in this direction so far, and the trend is consistent across rules going back to 2019.

The practical question for a primary care practice in 2026 is not whether proactive, full-visibility care is clinically valuable. It always was. The question is whether the practice will be among the first 30% of US primary care to operationalize it, the middle 50% that adopts when peer pressure forces it, or the last 20% that continues to leave six-figure annual CMS revenue on the table while practicing on 29% of the available clinical picture.

The economics of the choice are no longer ambiguous.
