Payment & Insurance Tips

Thank you for choosing Muir Orthopaedic Specialists (MOS) for your care and treatment. Although billing and payment is not always a comfortable topic, our financial policy and billing practices are part of your overall experience with our practice and we want to make it as seamless as possible.  The following information will help you understand our financial policy and aid you in planning for payment. 


MOS is contracted with Affinity Medical Group, John Muir Physician Network (JMPN) & CCHP. Please make sure that you have a valid referral or authorization prior to being seen. Please note that in certain situations re-authorization may be required.

Workers’ Compensation

In order for us to bill for a work related injury we must have an authorization from your workers’ compensation carrier prior to receiving treatment.  Should a work related injury be identified after treatment has begun we will not back bill your workers’ compensation carrier. Learn more about our Workers’ Compensation program

Auto accident (MVA) & personal injury

MOS does not bill auto insurance carriers or third party insurance carriers. Some personal health insurance carriers will pay for visits related to an MVA or personal injury, please contact your insurance carrier to verify this.  If your personal health insurance will not pay for these services, you will be considered a “self-pay.”

Self pay

Patients who do not have active health insurance coverage at the time of service are considered “self-pay.” When you check in at our Front Desk you will be asked to provide a $150 deposit (cash, check, credit card). Please keep in mind that this is only a deposit. Based on the complexity of your visit and any other services that are provided during the visit, such as x-rays, injections, casting or braces, your charges will be greater than $150. Payment in full is expected at the time of service. Your final balance will include a 20 percent discount off of our standard prices.


MOS and its providers are “participating providers.” This means that we accept Medicare’s allowed amounts for services rendered. Medicare will pay 80 percent of the allowed amount. The patient is responsible for the remaining 20 percent, plus any deductible. We will adjust off the difference between the MOS standard charges and Medicare’s allowed amount.

For patients who have a supplemental or secondary insurance plan, we will submit the claim for the remaining 20 percent once Medicare has paid. Please remember that even though we are participating providers for Medicare, the patient, by federal law, must be held responsible for any portion of the allowed amount that is not paid by Medicare or a secondary insurance plan.

Listed below are some of the major insurance plans that MOS providers are “In-Network” with. It is the patient’s responsibility to be aware of their insurance coverage, policy provisions and authorizations requirements. It is always a good practice to check with your insurance carrier to verify coverage prior to being seen. This can eliminate any surprise bills after you receive treatment.

Please keep in mind that you could receive a bill from multiple providers (facility, radiology, anesthesia, lab & MOS) that were involved in your treatment.

Overdue & in-collection accounts

Patients with past due accounts (balances 60 days or older) will be asked to make payment in full prior to being seen in the office for anything other than surgical follow-up. Patient accounts that have previously been sent to our collection agency will not be allowed to schedule appointments until their account has been paid in full.
