Virtual Gastrointestinal Endoscopy — CPB 0535 | AETNA Coverage Update

Aetna modified CPB 0535 governing virtual gastrointestinal endoscopy, effective November 27, 2025. Here's what billing teams need to do.

Aetna, a CVS Health company, updated its virtual gastrointestinal endoscopy coverage policy under CPB 0535 in the Aetna system. The policy covers CT colonography (CPT 74261, 74262, 74263) and MR enterography (CPT 74181–74183, 72195–72197) for Aetna members. If your practice bills these codes for colorectal cancer screening or diagnostic colonic evaluation, read this before your next claim goes out.

Quick-Reference Table

Aetna Virtual Colonoscopy Coverage Criteria and Medical Necessity Requirements 2025

Aetna's CPB 0535 coverage policy draws a sharp line between what qualifies as medically necessary and what gets denied. Know exactly which side your claims fall on.

Screening (CPT 74263): Aetna covers CT colonography screening every five years for average-risk, asymptomatic members aged 45 and older. That's it. No exceptions upward for high-risk patients using this code — those cases have a different pathway. If you bill CPT 74263 for a member under 45 or for a symptomatic patient, expect a claim denial.

Diagnostic CT colonography (CPT 74261 and 74262): Coverage requires one of seven specific clinical scenarios. Aetna considers diagnostic virtual colonoscopy medically necessary when symptomatic members have a known colonic obstruction and standard optical colonoscopy is contraindicated, when symptomatic members had an incomplete prior colonoscopy (for example, due to diverticulosis, obstructive or stenosing lesions, or redundant colon), when the member is on chronic anticoagulation that cannot be interrupted, when there are complications from a prior optical colonoscopy, when active diverticulitis creates elevated perforation risk, when increased sedation risk exists (such as COPD or a prior adverse anesthesia reaction), or when the symptomatic member needs colon examination fewer than 12 weeks after colon surgery.

That list is exclusive, not illustrative. If your documentation doesn't map to one of those seven criteria, Aetna will not cover CPT 74261 or 74262 as medically necessary. Your ICD-10 codes must reflect the clinical reality that triggers coverage — vague symptom codes won't survive review.

MR enterography (CPT 74181, 74182, 74183, 72195, 72196, 72197): Aetna considers magnetic resonance enterography medically necessary for monitoring members with known inflammatory bowel disease — specifically Crohn's disease — when small bowel disease or penetrating disease complications are present. This is a narrow indication. MR enterography for general IBD monitoring without small bowel involvement or penetrating complications does not meet medical necessity under this policy.

Aetna Virtual Colonoscopy Exclusions and Non-Covered Indications

This is where most claim denials happen. Aetna is explicit about what it considers experimental, investigational, or unproven under CPB 0535.

CT colonography is not covered for diagnosis of colorectal cancer or inflammatory bowel disease (Crohn's disease and ulcerative colitis) in members without a known colonic obstruction or an incomplete optical colonoscopy from obstructive or stenosing lesions. Diverticulosis alone, with or without symptoms, does not qualify. Surveillance for colorectal cancer or Lynch syndrome also falls outside covered indications. If your provider ordered a diagnostic CT colonography for Lynch syndrome surveillance, that claim will not pay under this policy.

MRI colonography — virtual colonoscopy using MRI rather than CT — is experimental for all indications under this policy. That includes screening, diagnosis of colorectal cancer, diverticulitis, inflammatory bowel disease, and Lynch syndrome surveillance. The MR enterography codes (CPT 74181–74183, 72195–72197) are covered for IBD monitoring per the narrow criteria above, but MRI-based virtual colonoscopy as a modality is categorically excluded. These are different procedures — make sure your team knows the distinction.

Virtual upper GI endoscopy using CT — for detection and evaluation of upper gastrointestinal lesions — is also experimental under this policy. No CPT code for CT-based upper GI virtual endoscopy will get reimbursement under CPB 0535.

The real issue here is documentation. A claim for diagnostic CT colonography after an incomplete colonoscopy needs to show why the colonoscopy was incomplete. "Incomplete colonoscopy" as a standalone code is not enough. Your documentation must support the specific pathology — diverticulosis, stenosing lesion, redundant colon — that drove the incompletion.

The effective date is November 27, 2025. Any claim for these services submitted on or after that date should reflect the updated criteria. Here's what to do now.

If your case mix includes a high volume of incomplete colonoscopy referrals or anticoagulated patients, the financial exposure here is real. Talk to your compliance officer before the November 27, 2025 effective date if you're unsure how this applies to your specific Aetna contracts.
