UnitedHealthcare told its network on September 1 that it is "eliminating 30% of prior authorization requirements" on October 1, 2026, for its commercial, Medicare Advantage, Community Plan, Individual Exchange and Oxford products (UnitedHealthcare provider notice, September 2026). Five attached lists run to roughly 1,700 codes, from arthroscopies and colonoscopies to genetic testing, chosen where approval rates were already "consistently high" (Healthcare Dive, September 2026).
The notice fulfils a May 5 commitment, made when the insurer said prior authorization applied to 2% of its medical services and that about 92% of requests were approved in under 24 hours (UnitedHealth Group, May 2026). The direction was known when the 2027 bids went in. The codes and the date were not, and both arrived after every 2027 rate the affected books will charge had been fixed.
Key Takeaways
- About 940 exchange codes and 1,400 Oxford codes come off the gate against roughly 120 for Medicare Advantage and D-SNP plans, so the books with the widest remaining gates lose the most and the book with the highest denial rate loses the least.
- June 1, 2026 was the 2027 Medicare Advantage bid deadline under 42 CFR 422.254 and August 20 the revised finalization date for HealthCare.gov exchange filings; the October 1 removal postdates both with no repricing window before January.
- 1.0 prior authorization requests per enrollee is UnitedHealth's 2024 Medicare Advantage rate, against 2.2 at Humana and 3.0 at Elevance, which is why a 30% cut of a narrow gate yields only about 120 codes (KFF, January 2026).
- 11% of prior authorization requirements had been removed industrywide by April under the AHIP and BCBSA pledge, more than 15% in Medicare Advantage, so competitors' 2027 bids carry the same exposure in smaller and earlier doses.
- Three of twelve months of the 2026 experience period that feeds 2028 pricing will run without the gate, leaving one quarter of ungated claims to set the utilization assumption for the first rating year in which no month is gated.
What the Five Code Lists Remove
A separate PDF covers each plan family. Healthcare Dive's count of those lists breaks down as follows (Healthcare Dive, September 2026):
- Commercial plans: more than 800 codes
- Individual Exchange plans: about 940 codes
- Medicare Advantage and dual special needs plans: approximately 120 codes
- Community Plan (Medicaid): from three codes in Washington, D.C. to more than 600 in Texas
- Oxford plans in New York, New Jersey and Connecticut: 1,400 codes
Those lists overlap. Five lists whose counts sum past 3,800 entries reduce to roughly 1,700 distinct codes, so the same joint injection or endoscopy code typically leaves the commercial, exchange and Oxford gates at once. Spokesperson Eric Hausman described the selection rule as "services with proven evidence of clinical efficacy, and where approval rates are consistently high" (Healthcare Dive, September 2026).
That rule fixes what the removal costs. A code approved 95 times in 100 was producing almost no denied dollars. The saving it generated came from requests that were never submitted and services that were never ordered because a request would have been required. The BMJ study of five Medicare Advantage insurers was built to count exactly that: services "deterred without a denial", inside a footprint where at least one insurer gated 40% of Medicare physician-service spending (BMJ, March 2024).
Medicare Advantage's list is short because its gate was already narrow. KFF's tally of 2024 CMS data puts UnitedHealth at 1.0 requests per enrollee, against 2.2 at Humana and 3.0 at Elevance, with a 12.8% denial rate, the highest of six large insurers (KFF, January 2026). The 2025 metrics insurers were required to post this year show the same shape: a 17% standard-request denial rate in Medicare Advantage, top of the six analyzed, and 21% on the marketplace (KFF, August 2026). A carrier that requests rarely and denies often has few high-approval codes to give up. Its exchange book had 940.
Where October 1 Falls on the 2027 Pricing Calendar
Under 42 CFR 422.254, each Medicare Advantage organization "must submit to CMS an aggregate monthly bid amount" no later than the first Monday in June, and the bid "must contain all estimated revenue required by the plan". In 2026 that Monday was June 1, eight weeks after CMS set the 2027 payment change at 2.48%, or 4.98% with risk-score trend (CMS, April 2026).
Exchange filings ran on a parallel track set out in CMS's February 23 bulletin: proposed filings by June 1 or July 15 depending on the state's rate review status, and no changes after July 15 (CMS bulletin, February 2026). HealthCare.gov filings were to be finalized by August 12, a date the Columbus II stay pushed to August 20 (Groom Law Group, August 2026).

Prior authorization rarely appears as its own line in a bid or a Unified Rate Review Template. Its savings sit inside the experience period. The paid-to-allowed relationship and the utilization per 1,000 in the base year already reflect the requests that were denied, the requests never submitted and the services never ordered. A 2027 bid built on 2025 experience and trended forward carries the full 2025 gate on every one of the 1,700 codes. The May 5 commitment let a bid actuary load a judgment factor for an unspecified cut on an unspecified date; it could not support a code-level assumption, because the codes did not exist until September.
By construction, the direct piece of the lost saving is small. On a code approved 95% of the time, denied dollars were at most 5% of requested spend, and the insurer's own 92% approval figure bounds the whole program. The deterrent piece has no ceiling of that kind, because it was never recorded as a denial.
Sizing it takes a code-level comparison the plan's actuaries can run once fourth-quarter claims mature: utilization per 1,000 on the removed codes against the same quarter a year earlier, with the codes that kept their gate as the control. Only the claims count captures the services that never generated a request.
Competitors carry the same exposure in smaller and earlier doses. AHIP and BCBSA reported in April that pledge signatories had removed 11% of prior authorization requirements since June 2025, more than 15% in Medicare Advantage, or 6.5 million fewer requests (AHIP and BCBSA, April 2026). Most of that came off before the June 1 bid, so it sits in competitors' 2026 experience and was visible to their 2027 assumptions. UnitedHealthcare's tranche is the one whose specifics landed after both calendars closed, on the book that locked its 2027 bids against a 2.48% payment increase.
The Data That Leaves With the Gate
That removal also takes away the instrument that measured the assumption. A prior authorization request arrives weeks before its claim, so request volume on a gated code is a leading indicator the plan reads for near-term utilization and for completing incurred-but-not-reported estimates. On October 1 that signal stops for 1,700 codes at once. The 2028 Medicare Advantage bid, due June 7, 2027, will be built on a 2026 base period with nine gated months and three ungated ones, and the ungated quarter will be the only evidence for a rating year in which no month is gated.
The exchange side compounds this with the 2027 experience it will produce. actuary.info's read of Washington's 2027 filings found carriers loading for post-subsidy adverse selection on top of trend. A 940-code removal in the individual market adds a utilization shift that the morbidity adjustment cannot separate from selection once both arrive in the same experience year, and the 2028 filing will have to attribute one claims-per-member movement to two causes.
Published metrics move the wrong way by construction. The site's coverage of the CMS transparency rule flagged that denial rates became public in 2026, and KFF's first read of the 2025 postings put UnitedHealthcare at 17% in Medicare Advantage and 21% on the marketplace for standard requests. Removing the codes with the highest approval rates leaves a residual gate that denies more often per request, so the 2026 metrics posted next year will show a higher denial rate on a smaller program, from the insurer whose rate was already the highest of six.
Those 120 Medicare Advantage codes sit on a thin margin. UnitedHealthcare guides its 2026 Medicare Advantage margin to the upper half of a 2% to 4% range, and its preliminary 2027 exit list stands at 34 counties after the 109 cut for 2026. Humana, shedding plans covering 600,000 members for 2027, reported a 1.8% second-quarter pretax Medicare Advantage margin. A utilization lift on 120 high-approval codes lands on a 2.48% payment increase already allocated between benefits, plan margin and, in WellMed's case, an outside owner's return. The cushion for an unpriced quarter of ungated claims is tens of basis points, and the quarter that will size it has not started.
