Insurance and Payment Policies

Warren Clinic physicians are participating providers for the Medicare program. This means patients pay only for the deductible, 20 percent coinsurance and any non-covered service. Our patient account services will file with Medicare for you. Warren Clinic also participates in the CommunityCare Senior Health Plan, a Medicare replacement HMO.

Payment Policies
Warren Clinic physicians participate in many PPOs and HMOs. Applicable copays, payment for non-covered services, or payment for service for which the patient files the claim are expected at the time of visit. Major credit cards are accepted in some Warren Clinic locations. The Clinic will file for payment from your primary insurance company, if your physician is a participating provider for your plan. The patient is ultimately responsible for payment. Should substantial medical services be required and the patient is unable to pay the full amount, a payment plan will be arranged.

For billing questions, in Vinita call 918-256-8731; in McAlester call 918-426-0240; in all other locations, call 918-488-6001, patient account services. Patient Accounting in Tulsa may also be contacted via e-mail at Please include the patient’s name and date of birth in the e-mail inquiry.

HMO Patients
Warren Clinic physicians are pleased to participate in most area HMOs. We appreciate the confidence you place in our physicians when you choose us as your primary care physician.

To receive maximum coverage under HMOs, both physicians and patients must be aware of HMO requirements. In nearly all instances, referrals to specialists must be approved by the primary care physician or a patient care committee in order for the services to be covered benefits. Specialty and facility referrals must be made to a network or contracted provider. We will make every effort to assure that your care follows your HMO’s requirements, but your cooperation and awareness of policies are also necessary.

Again, patients covered by HMOs should always contact their primary care physicians prior to receiving urgent or emergency services, except in the case of life threatening emergencies.
