Does Aetna cover colonoscopy?

Aetna will often cover a colonoscopy if it meets the following criteria: 

• Screening (preventive): Aetna considers a standard colonoscopy medically necessary every 10 years for asymptomatic, average-risk adults aged 45 and up, in line with United States Preventive Services Task Force (USPSTF) guidelines.
• High‑risk screening: If you have a family history of colorectal cancer or certain genetic conditions, Aetna covers more frequent colonoscopies starting at a younger age.
• Surveillance or diagnostic tests: Colonoscopies are also covered if you’re being tested due to symptoms, previous polyps, or inflammatory bowel disease.

What types of colonoscopy does Aetna cover?

While the colonoscopy procedure doesn’t change, as a diagnostic tool, colonoscopies fall under different categories: Aetna covers four major types of colonoscopy:

• Routine screening for average-risk individuals aged 45 and older with no symptoms.
• High-risk screening, based on personal or family history.
• Surveillance, such as annual colonoscopies for individuals with inflammatory bowel disease or a history of polyps.
• Diagnostic, when evaluating symptoms like rectal bleeding, pain, or unexplained changes in bowel habits.

What types are not covered?

Aetna generally does not cover colonoscopies requested for off-label reasons or individuals under the eligible age without qualifying risk factors. Procedures done out-of-network may also be denied unless prior approval is granted. Additionally, even if the procedure itself is covered, associated costs, such as anesthesia or facility fees, may be billed separately.

Eligibility criteria for Aetna coverage of colonoscopy

To qualify for full preventive coverage, you typically need:

• To be age 45 or older and asymptomatic, or 
• Meet the criteria for medical necessity, such as a personal history of colorectal issues or a high-risk family history. 

Additionally, the procedure must be performed by an in-network provider and at an in-network facility. Routine screenings usually do not require a referral or prior authorization, though diagnostic colonoscopies often do.

How to know whether my Aetna plan covers a colonoscopy

To verify your coverage:

• Check your Summary Plan Description (SPD) under the preventive services section.
• Log in to your Aetna member portal and search for “colonoscopy.”
• Call Aetna’s concierge or member services line to confirm that your provider and facility are in-network.
• Ask your GI practice for the CPT and diagnosis codes they plan to use, then call Aetna to confirm whether those codes are covered under your plan.

Does Aetna cover a colonoscopy if prescribed online?

Colonoscopy is an in-person procedure that requires a physical examination, so online prescriptions alone are not applicable. However, you may use telehealth to receive referrals or pre-procedure consultations, but the test itself must be completed at an in-person location.

Why Aetna might deny colonoscopy coverage

Coverage may be denied if there’s an age or indication mismatch, such as requesting a preventive colonoscopy before age 45 without risk factors. Other reasons include using out-of-network providers, missing referrals or prior authorizations (when required), or billing codes that don’t match the medical indication (for example, coding a screening as diagnostic).

Tips for improving approval chances

To avoid coverage issues:

• Confirm your provider and anesthesiologist are in-network.
• Get referrals or prior authorizations when needed.
• Make sure the billing codes match the reason for the procedure (screening vs. diagnostic).
• Document family history if it qualifies you for high-risk screening.
• Follow up with providers to refile claims or appeal denials promptly.

Alternatives and savings if Aetna doesn’t cover

If coverage is denied or you’re not eligible, you might consider alternatives such as CT colonography every five years (if eligible) or stool-based tests like FIT, FOBT, or Cologuard. For more affordable options, explore direct-pay services like ColonoscopyAssist, which supports uninsured or underinsured individuals. You can also file peer-to-peer appeals or request external reviews for coverage denials, especially for procedures over $500.

How to get prior authorization from Aetna for a colonoscopy

Your GI provider will submit a prior authorization request, including all necessary documentation, such as CPT and ICD-10 codes, along with relevant symptoms or health history. 

Aetna will review the request using their Clinical Policy Bulletin to determine if you’re eligible for coverage. You can expect a decision often within 7 to 14 days, but don’t hesitate to check the member portal or contact your provider for updates on the process. If denied, additional medical records or appeal documentation can be submitted.

Can your colonoscopy be covered by Aetna? 

Aetna covers colonoscopies for preventive, high-risk, surveillance, and diagnostic purposes, as long as you meet the eligibility criteria and the procedure is performed in-network. You’ll likely receive coverage. Understanding whether your procedure is classified as “screening” or “diagnostic,” and ensuring billing codes match your indication, is essential to avoiding surprise bills, so be sure to do your research beforehand, either on the Aetna portal or by calling a representative.
