From TekinHealthHealthcare Tech Field Notes

The Blue Cross Blue Shield Association analyzed claims data from 2023 to 2025 and found that as hospitals adopted AI coding tools — ambient scribes and automated chart-scanning software that flag secondary diagnoses — more patients were coded as medically complex without a matching change in the care actually delivered. BCBSA estimates this added $942 million in costs across its plans, with $653 million of that traced to more than 55,000 claims pushed into higher-paying complexity tiers by added secondary diagnoses, averaging about $11,000 per case. BCBSA says the figure excludes cases where documentation reflected genuinely new care. Hospital groups dispute the framing, saying patients are sicker and that AI tools are correcting years of underdocumented complexity.

Why it's notable: Health systems are adopting the same ambient-documentation and coding AI at scale (e.g., the VA's Abridge contract), and a major payer is now using claims data to contest how those tools shift reimbursement — a dispute that will shape audits and contract terms for any practice using AI scribing or coding software.

In a memo to providers, UnitedHealthcare listed about 1,700 medical codes that will no longer need prior authorization for services on or after October 1, 2026. The insurer says this is roughly 30% of its preapproval requirements. Healthcare Dive reported that the cuts include more than 800 codes for commercial plans, about 940 for ACA plans, about 120 for Medicare Advantage and dual special needs plans, and 1,400 for Oxford plans, with Medicaid varying by state. The affected services include oncology, cardiology, orthopedics, genetic and lab testing, physical, occupational and speech therapy, chiropractic care, home health and durable medical equipment.

Why it's notable: UnitedHealthcare covers more than 48 million people, so practices should re-check their prior authorization workflows and front-desk rules for these services before October 1. Only about 120 of the codes apply to Medicare Advantage, so the relief is uneven across plan types.

Candid Health raised a $120 million Series D led by Sixth Street Growth, with Oak HC/FT, 8VC and Y Combinator participating, announced July 21, 2026. The company sells software that automates billing, claims submission, denials and collections for provider groups. It says more than 200 healthcare organizations use it, annual recurring revenue grew 190% year over year, and total funding now exceeds $219 million.

Why it's notable: Investors are putting large sums into automating provider billing as payers use more automation of their own. For clinics, this means more vendors competing to take over claims work that staff do by hand today.

On May 13, 2026, CMS named 29 early adopters for its Electronic Prior Authorization Acceleration initiative, part of its Health Tech Ecosystem effort. They include health systems such as Cleveland Clinic, Providence, Ochsner Health, Sanford Health and Bon Secours Mercy Health; EHR vendors Epic, Oracle, athenahealth, eClinicalWorks, MEDITECH, ModMed and TruBridge; and networks including CommonWell and eHealth Exchange. Participants committed to building electronic prior authorization into clinical and billing systems, replacing fax and portal workflows, and showing clinicians where a request stands. The work is meant to get ready for January 1, 2027, when certain payers must support electronic prior authorization for medical items and services.

Why it's notable: Payers have to support electronic prior authorization by 2027, but clinics only benefit if their EHRs and health systems are wired in too. This puts the major EHR vendors on record committing to that work.

Iowa Gov. Kim Reynolds signed House File 2635 on May 13, 2026, effective July 1, 2026. The law says insurers may not use artificial intelligence as the sole basis for denying, delaying or downgrading medically necessary care, and a human clinical reviewer must be involved. It also removes prior authorization for recommended cancer screenings, sets deadlines for insurers to tell hospitals the status of a claim, and requires clinical explanations when care is denied. The bill passed the Iowa House 87-0 and was opposed mainly by insurers.

Why it's notable: Iowa joined a growing list of states putting rules on insurers' use of AI in prior authorization, which gives clinics grounds to challenge denials that were never reviewed by a clinician.

On April 10, 2026, CMS proposed a rule (CMS-0062-P) that extends its 2024 electronic prior authorization requirements to drugs. It would apply to Medicare Advantage plans, Medicaid and CHIP, and ACA exchange plans, and it adds small-group exchange insurers. Payers would need FHIR-based prior authorization APIs for drugs. ACA exchange plans would have to decide within 72 hours for standard requests and 24 hours for expedited ones, and Medicaid within 24 hours. Payers would also have to give a specific reason for every drug prior authorization denial. Most provisions would take effect October 1, 2027, and comments were due June 15, 2026.

Why it's notable: The 2024 rule left drugs out, and drug prior authorization is one of the biggest paperwork burdens in clinics. This proposal would bring it under the same electronic process, deadlines and denial-reason rules.

On January 11, 2026, as the J.P. Morgan Healthcare Conference opened, Anthropic launched Claude for Healthcare, a set of HIPAA-ready AI tools for health systems, payers and patients. It includes built-in connections to the CMS Coverage Database, ICD-10 codes, the NPI Registry and PubMed, which Anthropic pitches for prior authorization, claims appeals, coding and care coordination. The company says the product runs on its Claude Opus 4.5 model. Record company HealthEx said it had become the first way for consumers to connect their health records to Claude, and Apple Health and Android Health Connect integrations were set to roll out in beta in the Claude mobile apps.

Why it's notable: A second major AI lab is now selling HIPAA-ready tools that connect directly to the Medicare coverage and coding data behind prior authorization and appeals, one of the biggest administrative costs for clinics and payers.

CMS named the six companies that will run prior authorization reviews under its WISeR (Wasteful and Inappropriate Service Reduction) model in traditional Medicare: Cohere Health (Texas), Genzeon (New Jersey), Humata Health (Oklahoma), Innovaccer (Ohio), Virtix Health (Washington) and Zyter (Arizona). The vendors use AI and machine learning to review medical necessity for a short list of services CMS considers prone to waste, such as skin substitutes, electrical nerve stimulators and knee arthroscopy for osteoarthritis. Vendors are paid based on the Medicare savings they produce, adjusted for performance measures such as provider experience. Democrats in the House introduced a bill to block the pilot, but the model launched as planned on January 1, 2026, and runs through 2031.

Why it's notable: This brings prior authorization, run by AI vendors paid according to savings, into traditional Medicare for the first time. Clinicians in the six states now need prior approval for services that used to go through without it.

At HLTH 2025, Optum launched Optum Real, an AI-backed system that lets providers ask a payer in real time about a patient's benefits and whether a claim will be covered at the point of care, rather than weeks later during coding. The system uses AI to read payer contracts and policies. UnitedHealthcare is the first health plan on it, and Allina Health has been piloting it for outpatient radiology and cardiology claims, where it has processed more than 5,000 visits. Optum reported cuts in provider call volume of 25% to 42% and up to 75% fewer reimbursement submission errors in pilots.

Why it's notable: Claims denials and rework are a major cost for practices, and a payer-owned system that settles coverage questions up front could change how revenue cycle teams work, if payers beyond UnitedHealthcare adopt it.
