October brought changes across prior authorizations, Medicare coding, and hospice billing.
Update your work queues, reference materials, and staff instructions now. This is where avoidable denials will show up first.
1. UnitedHealthcare cut about 30% of prior authorization requirements
Effective October 1, 2026, roughly 1,700 codes no longer require prior authorization across most UnitedHealthcare plans. Requirements remain code-, plan-, and member-specific, and removing prior authorization does not guarantee payment. Claims can still be denied on medical-necessity review. Read the UHC notice here.
2. Centene is launching a nationwide prior-auth gold-card program
Announced October 13 and launching in November, 2026, the program is initially open to more than 160,000 qualifying providers for select outpatient services across Centene’s commercial, Medicare Advantage (MA) (Wellcare), and Medicaid lines. Gold-card status replaces prior authorization with pre-notification; it does not eliminate notification. Eligibility is provider- and service-specific. Read the Centene announcement here.
3. New Medicare National Correct Coding Initiative (NCCI) edits took effect October 1
The Q4 NCCI files apply to dates of service on or after October 1, 2026, covering procedure-to-procedure edits, Medically Unlikely Edits (MUEs), and add-on codes. Review the CMS NCCI edits here.
4. CMS reinforced its duplicate lab test denial policy
Medicare denies duplicate lab tests unless the repeat is medically necessary; modifier 91 identifies a medically necessary repeat. These denials often trace back to duplicate orders, overlapping panels, or missing documentation. More at the CMS NCCI FAQ library.
5. CMS flagged nursing-facility E/M coding risk for optometry
In its October 15 MLN Connects newsletter, CMS re-flagged an OIG finding: all 399 high-level E/M claim lines billed by optometrists for sampled nursing-facility enrollees failed Medicare requirements. Expect closer prepayment review wherever specialty, place of service, documentation, and E/M level don’t line up. Find the CMS fact sheet here.
6. New hospital billing-pattern reports released
CMS released the Q2 FY 2026 Program for Evaluating Payment Patterns Electronic Report (PEPPER) for short-term acute-care hospitals. Outliers can foreshadow record requests, audits, and recoupments, and can also surface undercoding and missed revenue. More about PEPPER reports.
7. Hospice election statement addendum is no longer request-only
The addendum isn’t new, but for elections on or after October 1 hospices must furnish it to every beneficiary, not only on request. Timing is unchanged: within 5 days of the election effective date, with updates within 3 days of a plan-of-care change. Through December 31, 2026, Medicare Administrative Contractors (MACs) will not deny claims solely for a missing or incomplete addendum. Find the First Coast notice here.
Emerging Signals
MA plans are tightening diagnosis validation
An HHS-OIG audit of UnitedHealthcare of Texas found records did not support the diagnosis codes for 172 of 230 sampled enrollee-years, with an estimated $24.4 million in overpayments for 2020–2021. UnitedHealthcare disagreed with some findings. Expect more record requests, validation reviews, and retrospective recoupments from MA plans. Read the OIG report here.
340B rebate model faces a legal challenge
On October 9, the American Hospital Association (AHA), the Maine Hospital Association, and four safety-net hospitals sued HHS and the Health Resources and Services Administration (HRSA) to block the revised 340B rebate model set to start January 1, 2027. Covered entities would pay wholesale acquisition cost up front and recover discounts later through rebates. Hospital analyses estimate more than $1 billion in annual administrative costs, compared with HRSA’s estimate of about $537 million. Read the AHA announcement here.
Where revenue cycle teams should focus
- Confirm UnitedHealthcare’s October authorization rules are in your payer matrices, and compare October authorization volume with September’s.
- Confirm Centene gold-card eligibility and pre-notification requirements by NPI/TIN, and separate pre-notification from full authorization in work queues.
- Monitor new NCCI, MUE, modifier, and add-on-code denials daily for the next 30 days.
- Audit duplicate-lab denials by CPT combination before correcting or appealing.
- Audit optometry nursing-facility E/M claims, starting with high-level codes and repeat patterns by provider.
- Compare PEPPER outliers against denial and aged A/R trends.
- Build the always-provide addendum workflow now, and track addendum deficiencies separately from denials through December 31.
- Add MA record requests, recoupments, and appeal deadlines to work-plan reviews.
- Model 340B rebate cash exposure and hold off on irreversible workflow changes until the lawsuit resolves.
