Does Medicare Pay for Endoscopy and Colonoscopy Together?

Medicare is a federal health insurance program that helps individuals manage healthcare expenses during retirement. It provides coverage for various medical services, supplies, and preventative care.

Medicare Coverage for Endoscopy and Colonoscopy

Endoscopy and colonoscopy are common medical procedures used to examine the digestive tract. An endoscopy involves inserting a thin, flexible tube with a camera through the mouth to view the esophagus, stomach, and upper small intestine. A colonoscopy involves inserting a similar tube through the rectum to examine the large intestine and rectum. Both procedures help diagnose conditions, investigate symptoms, or serve as screening tools for early detection of diseases like cancer.

Medicare Part B covers endoscopies when medically necessary for diagnosis or treatment. Medicare Part A may cover costs if an endoscopy occurs during an inpatient hospital stay. Colonoscopies are also covered under Medicare Part B, especially as a preventative service.

Medicare coverage for these procedures depends on whether they are classified as screening (preventative) or diagnostic. Screening colonoscopies detect polyps or cancer in individuals without symptoms. Medicare Part B covers these at no cost to the beneficiary if the provider accepts assignment. This full coverage applies once every 24 months for those at high risk for colorectal cancer, or once every 120 months (10 years) for those at average risk, or 48 months after a previous flexible sigmoidoscopy.

Diagnostic procedures are performed when a person has symptoms, a positive non-invasive screening test result, or when a healthcare provider finds and removes a polyp or other tissue during a screening. If a polyp is found and removed during a screening colonoscopy, Medicare reclassifies it as diagnostic. In such instances, Medicare still covers the procedure, but cost-sharing typically applies, unlike purely screening services.

When both an endoscopy and a colonoscopy are performed during the same encounter, Medicare can cover both procedures if medically necessary for diagnosis, treatment, or prevention. Performing these procedures together can be convenient for patients and efficient for healthcare providers. While Medicare reimburses for bundled procedures, the reimbursement rate for both procedures together may be less than the sum of charges if performed separately. Medicare Advantage (Part C) plans also cover these procedures, providing at least the same coverage as Original Medicare. However, Medicare Advantage plans may have their own specific rules regarding referrals or network providers that beneficiaries should confirm.

Understanding Your Financial Responsibility

With Original Medicare (Parts A and B), out-of-pocket costs include deductibles, coinsurance, and copayments. Medicare Part B has an annual deductible, which is $257 in 2025. After this deductible is met, Part B covers 80% of the Medicare-approved amount for most covered services, leaving the beneficiary responsible for the remaining 20% coinsurance.

The classification of the procedure significantly impacts these costs. For a screening colonoscopy, if the provider accepts Medicare assignment, beneficiaries pay nothing for the test, and the Part B deductible does not apply. However, if a polyp or other tissue is found and removed during screening, the procedure shifts to diagnostic. In this diagnostic scenario, the Part B deductible may apply, and beneficiaries are responsible for 20% coinsurance of the Medicare-approved amount for doctor’s services. Additionally, if the procedure takes place in a hospital outpatient setting, a separate facility coinsurance may also be incurred.

Medicare Advantage (Part C) plans may have different cost-sharing structures compared to Original Medicare. These plans often include specific copayments for services, which can vary by plan. While Medicare Advantage plans must cover the same services as Original Medicare, their out-of-pocket costs, such as copays and coinsurance, might differ. Many Medicare Advantage plans also include an annual out-of-pocket spending limit.

For those with Original Medicare, Medigap policies can help cover out-of-pocket costs like deductibles, coinsurance, and copayments not covered by Original Medicare. Medigap plans are offered by private companies and can reduce the financial burden.

Navigating the Process for Coverage

A doctor’s order is necessary for these procedures. How the healthcare provider codes the procedure, as screening or diagnostic, directly influences Medicare billing and coverage. Accurate coding is essential to reflect the medical necessity and type of service provided.

Individuals enrolled in Medicare Advantage plans should inquire about prior authorization or referral requirements before a procedure. While Original Medicare typically does not require prior authorization for most services, Medicare Advantage plans often do for a wider range of services, including higher-cost items or inpatient hospital stays. Confirming these requirements with your plan in advance can help prevent unexpected costs or claim denials.

After receiving medical services, beneficiaries with Medicare Advantage or Part D plans receive an Explanation of Benefits (EOB). This document is not a bill, but a summary of services received, the amount billed, what the plan covered, and any remaining amount for which the beneficiary is responsible. Reviewing the EOB allows beneficiaries to understand how claims were processed and identify potential discrepancies. Communicating with the healthcare provider’s billing department beforehand is advisable to confirm coverage details and obtain an estimate of potential out-of-pocket costs. This proactive approach can help beneficiaries plan financially and avoid surprises.
