Insurance and prior authorization

  • Prior authorization: our office contacts your insurance company to obtain prior authorization for your procedure.
  • Know your policy: it is your responsibility to understand your benefits. Call the member services number on your insurance card to confirm coverage and your out-of-pocket costs (deductible, copay, and coinsurance).
  • HMO and IPA plans need an approved referral or authorization before your procedure can be scheduled. See accepted insurance.
  • Surveillance colonoscopy (commercial insurance): if you have a history of colon polyps and your colonoscopy is done less than 10 years after your last one, your insurance may not consider it "screening" or "preventive." Your deductible and copay may apply.

Check your coverage with these codes

Your insurance company can tell you what you will owe if you give them the procedure (CPT) and diagnosis (ICD-10) codes. These are the codes most often used for our procedures. Your final codes depend on what is done during the procedure, such as biopsies or polyp removal.

Screening vs. diagnostic colonoscopy

Under the Affordable Care Act, most private plans cover a screening colonoscopy for average-risk adults 45 and older with no cost to you, including removal of polyps found during the screening. A colonoscopy done because of symptoms, such as bleeding or a change in bowel habits, is diagnostic and may involve a deductible, copay, or coinsurance. Medicare covers screening colonoscopy; if a polyp is removed, a small coinsurance may apply, which is being phased out by 2030.

Surveillance after polyps: with commercial insurance, a surveillance colonoscopy done less than 10 years after your last one because of a history of colon polyps may not be considered "screening" or "preventive," so your deductible and copay may apply. Coverage varies by plan, so call your insurance with the codes above before your procedure.

Understanding your Explanation of Benefits (EOB)

  • Total charges: the amount first billed to your insurance company. It is discounted to the contracted fee the provider accepts under its agreement with your plan.
  • Allowed amount: the total the provider expects to receive from your insurance and you combined (also called the negotiated or expected amount).
  • Payable amount: what your primary insurance will pay.
  • Patient responsibility: the difference between the allowed and payable amounts, including deductibles, copays, coinsurance, and uncovered amounts. Secondary insurance may pay all or part of this, depending on your plan.

Cancellation fee

Please note: fees may apply if you cancel within 5 business days of your scheduled procedure.

Procedure Billing FAQs

How many bills will I get for my procedure?

Usually up to four: one from the gastroenterologist (billed by Genesis Healthcare Partners), one from the hospital or surgery center, one from the anesthesia provider if propofol sedation is used, and one from the pathology lab if biopsies are taken or polyps are removed.

Who do I call about my doctor's bill?

Call our billing department at 858-888-7730. For questions about the facility, anesthesia, or pathology bills, contact the company listed on that bill.

Can you tell me what the surgery center will charge?

No. We do not quote facility fees. Please contact the hospital or surgery center where your procedure is scheduled.

When do I pay for anesthesia?

If propofol anesthesia is used, payment to the anesthesia provider is required in advance or on the day of your procedure.

Do you get prior authorization from my insurance?

Yes. Our office contacts your insurance company to obtain prior authorization. It is still important to call your insurance to confirm your coverage and out-of-pocket costs.

Why was my screening colonoscopy billed as diagnostic?

A colonoscopy is billed as diagnostic when it is done for symptoms such as bleeding or a change in bowel habits. Your insurance decides how much you owe based on your plan. Call your insurance with the CPT and ICD-10 codes on this page to check your coverage.

Is a follow-up colonoscopy after polyps considered screening?

Not always. With commercial insurance, a surveillance colonoscopy done less than 10 years after your last one because of a history of colon polyps may not be considered screening or preventive, so your deductible and copay may apply. Check with your insurance before your procedure.

Is there a fee if I cancel?

Fees may apply if you cancel within 5 business days of your scheduled procedure.

PPO & Medicare welcome

See a gastroenterologist, usually without a referral

Our board-certified gastroenterologists are in network with most PPO plans, including Aetna, Anthem Blue Cross, Blue Shield of California, Cigna, and UnitedHealthcare, plus Medicare. Most PPO plans need no referral, and healthy adults 45 and older can often schedule a screening colonoscopy without an office visit.
