The CY 2027 Hospital Outpatient Prospective Payment System and Ambulatory Surgical Center proposed rule (CMS-1850-P), released July 2 and published in the Federal Register July 7, closes for comment on August 31, 2026 — three days from today. It is the shorter of the two open clocks and the one most physician practices will let expire without filing. That is a mistake, because this rule decides where a large block of surgical volume gets performed starting January 1.
| Provision | Current | Proposed CY 2027 |
|---|---|---|
| OPPS and ASC payment update | — | +2.4% (3.2% market basket less 0.8 pt productivity) |
| 340B-acquired drug payment | ASP +6% | ASP −33.4% |
| 340B remedy offset | 0.5% | 3.0% |
| Non-drug OPPS services (budget neutrality) | — | +8.44% |
| Removed from the Inpatient-Only list | — | 637 (801 more in CY 2028) |
| Added to the ASC Covered Procedures List | — | 618 |
CMS conducted a new acquisition-cost survey and proposes paying ASP minus 33.4% for 340B-acquired outpatient drugs. CMS estimates the change reduces Original Medicare drug payment by $4.55 billion and beneficiary drug cost-sharing by $1.15 billion in the first year. Because OPPS is budget-neutral, that money does not leave the system: payment rates for non-drug outpatient services rise approximately 8.44% to absorb it. Separately, the ongoing 340B remedy offset applied to affected hospitals rises from 0.5% to 3.0% beginning in CY 2027.
CMS proposes removing 637 procedures from the Inpatient-Only list for CY 2027 — roughly half of what remains — with the other 801 more clinically complex procedures scheduled to come off in CY 2028, completing a three-year phase-out. In parallel, CMS proposes adding 618 surgical procedures to the ASC Covered Procedures List, including stakeholder-nominated codes and codes proposed for removal from the IPO list.
For an orthopedic, GI, ENT, urology, or spine group with an ASC interest, the ASC list expansion is the single most valuable regulatory development of 2026 — and its comment deadline is Monday. For a practice without an ASC, the same expansion is a referral-pattern and contract-rate event: commercial payers reprice site-of-service differentials off the Medicare list.
CMS proposes extending site-neutral payment reductions to additional imaging services furnished in excepted off-campus provider-based departments — narrowing the hospital-outpatient payment arbitrage that has driven a decade of physician-practice acquisitions. Combined with the 340B repricing, the CY 2027 OPPS rule is the most direct federal compression of hospital-versus-independent payment differentials in several cycles.
The CY 2027 Physician Fee Schedule (CMS-1848-P) closes September 14, 2026 — 17 days out. Notably, the SBA Office of Advocacy convened a small-business roundtable on the CY 2027 PFS proposed rule on August 21, 2026, expressly to collect independent-practice impact evidence for the record. Practices that missed it can still file directly at regulations.gov under file code CMS-1848-P.
OPPS/ASC closes August 31. PFS closes September 14. They move different money for different specialties, and a comment filed on the wrong docket does not count. Confirm which rule carries your issue before you write.
June 2025’s voluntary prior authorization commitments — signed by roughly 50 health plans, including all six of the largest publicly traded insurance conglomerates (Elevance Health, Centene, Cigna, CVS Health’s Aetna, Humana, and UnitedHealthcare) — now have a first full year of results attached to them.
Eleven percent is measurable relief in staff hours, and 6.5 million avoided requests is not a rounding error. But the 2025 CAQH Index puts medical electronic prior authorization adoption at 40%, meaning three out of five prior authorization transactions still run through a phone call, a fax, or a portal keystroke. That is the gap the 2027 deadlines are built to close. UnitedHealthcare separately reports its Gold Card program cut authorization volume by an average of 30% for eligible provider groups in 2025 — the largest single reduction available to any practice, and one gated on volume thresholds most small practices do not clear.
Under CMS-0057-F, impacted payers must have the Provider Access API and the Prior Authorization API operational on FHIR by January 1, 2027. Plans must allow a practice to determine whether an item or service requires authorization, identify the specific documentation required, submit the request, and receive the decision inside the EHR or practice management system. CMS extended this deadline once already, from 2026 to 2027, to give payers time to work with EHR vendors — there is no indication of a second extension.
| Requirement | Effective | What it means for a practice |
|---|---|---|
| Decision timeframes and specific denial reasons | Jan 1, 2026 — live | Every denial must carry a specific reason; use it as appeal input, not a filing artifact |
| Five-year PA history retention | Jan 1, 2026 — live | You can request a payer’s own authorization history in a dispute |
| Provider Access and Prior Authorization FHIR APIs | Jan 1, 2027 — 126 days | Submit and receive PA from inside the EHR — if your vendor is integrated |
| Public PA metrics reporting | 2027 | Total requests, approvals, denials, average processing times — contract leverage |
| BCBSA: 80% of e-PA submissions answered in real time | Goal: Jan 1, 2027 | Voluntary commitment across lines of business |
Ask each of your top five payers, in writing, for their CMS-0057-F Prior Authorization API implementation date and their EHR integration partner list. Practices not on a payer’s early-integration roster in Q4 2026 will spend most of 2027 still faxing while their competitors submit from inside the chart.
While pledge signatories were cutting authorization requirements, providers reported rising clinical claim denials over the same period — faster payment processing paired with significant revenue loss on the clinical-denial side. Faster cash flow with more clinical denials is not a net win. It is a relocation of the fight from the front end to the back end, where each contested claim costs materially more to resolve.
The most expensive unautomated object in the revenue cycle is not a claim. It is a phone call — a billing specialist on hold with a payer to verify benefits, chase a status, or argue a denial. This week the automation frontier moved directly onto it.
EHVA.ai and CareFactor, a Columbus, Ohio third-party administrator with more than 60 years in health coverage, announced a partnership with a stated target of resolving 80% of provider calls with voice AI for benefits administration. Cigna Healthcare separately announced on August 26 that it is significantly expanding AI-enabled and predictive-analytics care management to support 20% more customers with emerging, complex, or chronic needs — cancer, heart disease, kidney disease, high-risk pregnancy, and behavioral health.
The 2025 CAQH Index found that more than 50% of health plans now use AI tools in administrative workflows — against just 25% of provider organizations. Payers are automating the interaction at twice the rate providers are. When one side of a transaction runs on models and the other runs on hold music, a volume asymmetry becomes a leverage asymmetry. That is the practical case for provider-side automation, and it does not require believing any vendor’s ROI claim.
Autonomous coding is no longer a capital project waiting on proof. KLAS has published its first market report dedicated to the category — Nym scored 89.6 overall across 12 unique customers — and has begun issuing Emerging Company Spotlights on individual vendors. Once a category is measured, it is negotiable. Ask for the KLAS score and the customer count before you ask for the demo.
Deloitte reports roughly 80% of health systems are investing in agentic AI across revenue cycle, day-to-day operations, and care delivery. But survey data on what is actually deployed tells a narrower story: 52% of organizations report clinical documentation tools in production, versus 36% for revenue cycle, coding, and billing applications. Documentation got the first budget cycle. Billing is getting the second — which means the vendor market for RCM AI is entering its competitive phase, and pricing is softer now than it will be in 2027.
October 1, 2026 is 33 days away, and this year it carries two separate code-set activations instead of one. Most practices have the ICD-10 update on the calendar. Very few have the CPT Category III update on it.
CMS has posted the complete FY 2027 diagnosis code files, including the addendum and conversion table. The additions cluster in injury and poisoning (85), pregnancy and childbirth (56), and musculoskeletal (33), with further additions covering Clostridioides difficile infection, body mass index, and hypoglycemia. The codes apply to discharges and patient encounters occurring from October 1, 2026 through September 30, 2027.
In its July biannual update for the CPT 2027 cycle, the AMA released 58 Category III codes plus three revised descriptors — ranges 0894T–0896T and 1054T–1111T — with an October 1, 2026 effective date. Category III codes track emerging technology and services. They are typically payer-discretion for coverage, but they are also the only correct way to report the service: submitting an unlisted code where a Category III code exists is a documented and avoidable denial driver.
Run clearinghouse acceptance testing against October 1 dates of service for both code sets before the last week of September. Testing ICD-10 alone will not surface a Category III rejection, and the first place you will find out is a remittance three weeks into the quarter.
AMA has revised the Category III early-release schedule: updates now publish in April, July, and October — three times a year, up from twice. A practice running an annual January coding-update ritual is now structurally three releases behind by December. This is a calendar change, not a content change, and it costs nothing to fix.
The Adonis 2026 Revenue Cycle Management Report, built on interviews with revenue cycle leaders across hospitals, health systems, and provider groups, found that external payer dynamics have overtaken staffing and internal inefficiency as the top threat to revenue performance. The operational figure underneath that finding is the one to bring to your next practice meeting.
Experian Health’s State of Claims survey supplies the provider-side confirmation. 54% of providers say claim errors are increasing. 50% name missing or inaccurate claim data as the single largest driver of rising denials — ahead of authorizations and incomplete patient information. And while 67% believe AI would improve the claims process, only 14% are actually using AI against denials. Adonis adds the governance signal: more than one in three revenue cycle leaders now report that denial impact is discussed at the executive level.
Automated eligibility verification drops the cost of a check from $3–$5 manual to under $1, and practices report recovering 10–15 staff hours per week. Verifying at multiple touchpoints rather than only at registration reduces denials by an estimated 20–30%. Documented implementations show clean-claim rates moving 96.5% to 98% and Days in A/R falling from 45 to 26. None of that requires an AI strategy — it requires an API and a workflow decision.
| Metric | Industry average | Target | Warning threshold |
|---|---|---|---|
| First-pass clean claim rate | 90–94% | ≥ 95% | < 90% |
| Total denial rate | 9–12% | ≤ 5% (top quartile) | > 10% |
| Days in A/R | 40–45 | ≤ 28 | > 45 |
| A/R over 90 days | 18–22% | ≤ 12% | > 25% |
| Cost to rework a denied claim | $57.23 average | Prevent, do not rework | $25–$118 range |
| Electronic prior authorization | 40% | ≥ 90% | < 40% |
| Point-of-service collection rate | ~25% | ≥ 40% | < 20% |
Convert the 50–75 hour figure into your number this week. Denied claims per month × roughly 25 minutes of touch time × loaded hourly staff cost. That dollar figure — not the denial percentage — is the business case for front-end automation, and it is the number a physician-owner will actually act on.
EnableComp, the Franklin, Tennessee complex-claims and denials specialist, acquired Ohio-based Helix Advisory on August 17, 2026 — terms undisclosed, as both companies are private. EnableComp already recovers roughly $3 billion annually across more than 1,000 hospitals in complex claims and denials. What it did not have was zero-balance review: the discipline of re-examining claims that were already paid, closed, and filed — but paid incorrectly.
Zero-balance is the last unmined seam in the revenue cycle for a structural reason: a correctly-formatted underpayment never appears on a worklist. It posts as a payment. The same blindness that lets algorithmic downcoding pass unnoticed lets contractual underpayment pass unnoticed. A denial generates work; an underpayment generates a deposit. The acquisition market has now put a price on that asymmetry, which is the clearest signal available that the recovery is worth the effort.
KLAS’s inaugural Revenue Cycle Management Suites 2026 report studies organizations running at least three distinct RCM modules — claims, eligibility, denials, insurance discovery — from a single vendor. The primary drivers of going all-in with one vendor are vendor consolidation (57%) and a stronger strategic partnership (57%), followed by pricing (43%) and expanded functionality (41%). Waystar’s overall “A” was attributed to strategic partnership, a cohesive interface across acquired modules, price bundling that reduces nickel-and-diming, and high adoption of AI-generated appeals.
If your practice is evaluating an RCM suite this fall, the KLAS finding to negotiate against is price bundling. The single most-cited satisfaction driver among top-rated suite customers is the absence of per-module nickel-and-diming — which means it is a concession vendors have already demonstrated, in public, that they will make.
The updated machine-readable file requirements finalized in the CY 2026 OPPS/ASC final rule took effect January 1, 2026, with CMS enforcement beginning April 1, 2026. The substantive change was the strengthened attestation. A hospital must now affirm that, to the best of its knowledge and belief, it has included all applicable standard charge information in accordance with 45 CFR 180.50, that the encoded information is true, accurate, and complete as of the file date, and that it has included all payer-specific negotiated charges in dollars that can be expressed as a dollar amount. Hospitals must also rely on standardized data sources and report more precise allowed-amount information. CMS publishes a public list of hospitals issued civil monetary penalties, and a CMP may be reduced where a hospital waives its right to an Administrative Law Judge hearing.
And CMS is already reopening the framework. The CY 2027 OPPS proposed rule carries a Request for Information on strengthening the standardization and comparability of hospital price transparency data — consistency, comparability, and consumer usability. It closes with the rest of the rule on August 31.
Independent practices are not subject to the hospital MRF rule, but many use hospital machine-readable files to benchmark their own commercial rates against the hospital across the street. If you have ever pulled an MRF for contract negotiation, you have a direct interest in this RFI — and almost no independent practice files on it.
The Wasteful and Inappropriate Service Reduction model has been live since January 15, 2026 and runs through December 31, 2031. It operates in six states across four MAC jurisdictions: New Jersey (JL), Ohio (J15), Oklahoma and Texas (JH), and Arizona and Washington (JF). It applies prior authorization to selected Traditional Medicare services historically associated with fraud, waste, abuse, or low value — including skin and tissue substitutes, electrical nerve stimulators, and epidural steroid injections for pain management. Contractors use artificial intelligence combined with clinical review, applying existing Medicare coverage policy and patient-safety standards, with standard decisions in three business days.
A prior authorization workflow scoped to commercial and Medicare Advantage has a live gap in NJ, OH, OK, TX, AZ, and WA. WISeR puts prior authorization into fee-for-service Medicare — a place most practices have never had to build one.
Healthcare bankruptcy filings overall settled back into their long-run pace in the first half of 2026. Physician practices did not.
According to the Gibbins Advisors mid-year report released July 20, 2026, clinics and physician practices accounted for nearly 30% of qualifying healthcare Chapter 11 filings in the first half of 2026 — seven filings — making it the one subsector climbing while the rest ran flat or down. Annualized, that is 14 filings for the year, against six in 2025 and a previous high of 10 in 2024: the highest annual total since tracking began in 2019. Across the whole sector, if the H1 pace holds, 2026 finishes with 52 Chapter 11 filings — a 16% increase over 2025.
Filings by companies with $10 million to $50 million in liabilities are on pace to finish 2026 up 57% — 36 projected versus 23 last year. That is not the distressed-health-system tier. That is the multi-site independent group tier. And the figure understates real attrition, because most small practices in financial distress close, sell, or wind down without ever entering a qualifying bankruptcy proceeding.
The reported drivers, in order: reimbursement pressure, claim denials, and operating costs. That maps precisely onto the Veradigm survey of 360 independent practice leaders, in which 54% reported increased financial pressure over the past year, 48% reported rising claim denial volumes, and only 24% reported high or complete visibility into where they are losing revenue.
In that same survey, 69% of leaders at independent, physician-owned ambulatory organizations said they are extremely or very confident their practice will remain independent over the next three to five years. Independence is not collapsing. It is being squeezed — and the squeeze is now showing up in a bankruptcy statistic rather than only in an acquisition statistic.
| Metric | Typical independent practice | Where you should be |
|---|---|---|
| Revenue-leakage visibility | 24% report high visibility | Monthly write-off and underpayment report by payer |
| First-pass clean claim rate | 90–94% | ≥ 95% |
| Days in A/R | 40–45 | ≤ 28 |
| Denial rate | 9–12%; 41% of providers above 10% | ≤ 5% |
| Electronic prior authorization | 40% industry-wide | ≥ 90% of PA volume electronic by Q2 2027 |
| Eligibility verification | Manual, $3–$5 per check | Automated, under $1, at 2+ touchpoints |
| Zero-balance / underpayment review | Rarely performed | Quarterly review of paid-and-closed claims |
| Days of cash on hand | Often under 30 | ≥ 60 |
The single highest-yield report an independent practice can run this quarter is a zero-balance review — paid, closed, and filed claims re-checked against contracted rates. It requires no new software and no new headcount to start, and the acquisition market just told you, in dollars, what that seam is worth.
CY 2027 PFS proposed specialty impacts, paired with the OPPS/ASC provisions that hit each specialty differently. All PFS figures are proposed and subject to the September 14 comment record; all OPPS/ASC figures close August 31.
| Specialty | This week’s number | What it means |
|---|---|---|
| Primary Care | G2211 → 16% modifier (32% in MSSP ACOs / LEAD) |
The proposed conversion from flat add-on to percentage modifier makes capture rate materially more valuable. Audit G2211 attachment on longitudinal-care E/M visits now. |
| Cardiology | ~+1% total allowed charges vs. 2026 | Roughly flat is a win in this cycle. The exposure is site-neutral imaging expansion in excepted off-campus PBDs, which repositions where diagnostics get performed. |
| Orthopedics | −7% specialty impact | The steepest proposed decline of any major specialty — before the modifier 25 provision. The offsetting upside is the 618 procedures proposed for the ASC Covered Procedures List. |
| Oncology | 340B: ASP+6% → ASP−33.4% −$4.55B Medicare drug payment |
The largest dollar provision in the OPPS rule. Beneficiary drug cost-sharing falls $1.15B, and the 340B remedy offset rises from 0.5% to 3.0%. |
| Radiology | Diagnostic and nuclear medicine ~+2% Interventional and radiation oncology ~+3% |
Among the few specialties with positive proposed impacts. Site-neutral imaging expansion is the offsetting risk to model. |
| Neurology | ~0% projected total payment change | CMS projects no net change — but that projection excludes expiration of the temporary 2.5% increase Congress provided for 2026. Traditional MIPS reporting also ends. |
| Behavioral / Mental Health | Final year of the four-year timed behavioral health work RVU transition | CY 2027 adds smoking and tobacco cessation and SBIRT to the transition, plus proposed new codes and guidelines for group (“shared”) medical appointments — a new billable structure for group therapy. |
| Gastroenterology | 637 procedures proposed off the IPO list +2.4% ASC update |
The IPO phase-out and ASC list expansion are the largest site-of-service changes GI has seen in years. Endoscopy-heavy groups with ASC ownership are the direct beneficiaries. |
Two of the eight specialties above are moved primarily by the Physician Fee Schedule (September 14) and four are moved primarily by the OPPS/ASC rule (August 31). If your practice has an ASC interest, the deadline that matters to you is Monday — not the one three weeks out.
Ten moves for the week of August 28, 2026 — each tied directly to something in this issue.
