Subject: REMINDER: UnitedHealthcare Medicare Advantage Referral Enforcement Begins 05/01/26

⚠ ACTION REQUIRED United Healthcare will begin denying claims for specialist services rendered without a PCP referral starting May 1, 2026. Denied claims are provider liability — patients cannot be balance billed.

Bottom Line

In January 2026, UnitedHealthcare introduced a new referral requirement for its Medicare Advantage HMO and HMO-POS members nationwide. For pain management practices, this policy applies to all pain management services regardless of provider specialty1. Since January 1, UHC has not been denying claims for missing PCP referrals — but that grace period ends April 30. Starting May 1, 2026, claims submitted without a required referral on file will be denied and the financial liability falls on the practice. This applies to UHC Medicare Advantage HMO and HMO-POS plans only. PPO plans, Institutional SNP plans, Erickson Advantage plans, and the Michigan Integrated DSNP plan (H2247-005) are not affected. Traditional Medicare is not affected.

(1) Anesthesiology is generally exempt from the referral requirement; however, UHC explicitly requires a PCP referral when an anesthesiologist is providing pain management services

Which UHC Plans are Affected

Affected — Referral Required	Not Affected — No Referral Required
Medicare Advantage HMO plans	Medicare Advantage PPO plans
Medicare Advantage HMO-POS plans	Institutional SNP (I-SNP) plans
	Erickson Advantage plans
	Michigan Integrated DSNP (H2247-005)
	Traditional Medicare (Original Medicare)

Note: California, Nevada, and Texas already had state-level referral requirements in place prior to 2026. Those existing rules remain unchanged and UHC does not separately track or enforce referrals in those states — delegated entities manage requirements locally. Practices in those states should confirm requirements with the applicable delegate.

How to Submit a Referral

• Referrals must be submitted by the patient's PCP to UnitedHealthcare prior to the specialist visit — the specialist practice cannot submit on the PCP's behalf

• Referrals are effective immediately upon submission by the PCP

• A referral start date of up to 5 calendar days prior to the entry date may be selected • Specialists within the same specialty and under the same Tax ID (TIN) do not require separate referrals

• Submit and verify referrals through the UnitedHealthcare Provider Portal at uhcprovider.com

• For delegated members (e.g., WellMed), referral processes may differ — contact the delegate directly

---

Recommended Actions Before May 1ST

• Audit your UHC Medicare Advantage patient panel now. Identify all active patients on HMO or HMO-POS plans. Confirm plan type — PPO patients do not require a referral.

• Contact PCPs for patients scheduled after May 1. For any UHC HMO patient with appointments on or after May 1, ensure the PCP has submitted a referral before the visit.

• Update your intake and scheduling workflow. Require referral verification before booking UHC HMO/HMO-POS patients for pain management services.

• Do not turn patients away or balance bill. If a referral is missing, the claim denial is provider liability. Patients are protected and cannot be billed for the difference.

• Contact your HCI account manager if you need help identifying affected patients in your billing system or updating your eligibility verification workflow.
