Aetna modified CPB 0737 covering double balloon enteroscopy, effective November 15, 2025. Here's what billing teams need to know before submitting claims.
Aetna, a CVS Health company, updated its double balloon enteroscopy coverage policy under CPB 0737 in the Aetna system. The policy defines nine covered indications and seven experimental designations for DBE procedures. If your gastroenterology or surgery practice bills Aetna for small bowel endoscopy, this is the policy that determines whether your claims pay or deny.

Aetna Double Balloon Enteroscopy Coverage Criteria and Medical Necessity Requirements 2025
The Aetna double balloon enteroscopy coverage policy under CPB 0737 is more specific than most small bowel policies you'll encounter. Aetna defines nine distinct indications for medical necessity — and if your documentation doesn't map to one of them, the claim won't hold up on review.
The nine covered indications are:
| # | Covered Indication |
|---|---|
| 1 | Dilation of small bowel strictures in Crohn's disease |
| 2 | Evaluation of suspected small bowel malignancies — including adenocarcinoma, lymphoma, GI stromal tumors, and metastatic tumors (ICD-10 codes C17.0–C17.9, C78.4, and the C81–C88 lymphoma range apply here) |
| 3 | Colon evaluation when colonoscopy (CPT 45378) was incomplete |
| 4 | Suspected Meckel's diverticulum with inconclusive imaging — specifically when CT (CPT 74176, 74177, or 74178) or Meckel's scan (CPT 78290) was non-diagnostic |
| 5 | Obscure GI bleeding with objective evidence — iron-deficiency anemia (ICD-10 D50.0–D50.9), positive fecal occult blood, or visible bleeding — or suspected Crohn's disease that tested negative on capsule endoscopy (CPT 91110), small-bowel follow-through, EGD (CPT 43235), and colonoscopy |
| 6 | Removal of entrapped foreign bodies, including retained video capsules |
| 7 | Removal of large polyps (greater than 10 mm) in Peutz-Jeghers syndrome patients |
| 8 | Treatment of confirmed small intestinal GI bleeding |
| 9 | ERCP (CPT codes 43260–43273, plus HCPCS C7541–C7544 and C7560) in patients with surgically altered upper GI anatomy — including those who've had Roux-en-Y procedures (CPT 47780, 47785) |
Medical necessity documentation is everything here. Aetna requires that the clinical picture match the indication — not just the procedure code. If you're billing for Crohn's-related stricture dilation, your chart should show the Crohn's diagnosis and the clinical basis for the dilation, not just the procedure note.
The policy doesn't explicitly state prior authorization is required on its face, but DBE is a high-cost, high-scrutiny procedure. Your Aetna contract and plan-level benefits determine prior auth requirements. Check those before scheduling, not after. If you're unsure, call the plan — a claim denial on a DBE is expensive to fight.
Reimbursement for DBE claims depends on correct ICD-10 coding. Aetna uses diagnosis codes to validate medical necessity. Mismatched or nonspecific diagnosis codes are the fastest path to a denial.
Aetna Double Balloon Enteroscopy Exclusions and Non-Covered Indications
Seven indications are explicitly experimental, investigational, or unproven under this coverage policy. Aetna won't pay for DBE when performed for:
| # | Excluded Procedure |
|---|---|
| 1 | Detection of neuroendocrine tumors of the small bowel — this is notable, because carcinoid tumor codes (C7A.10–C7A.19, D3A.10–D3A.19) appear in the ICD-10 code list but map to an excluded indication |
| 2 | Diagnosis and treatment of small bowel varices |
| 3 | Diagnosis of pelvic mass penetrating intestine, including gossypiboma |
| 4 | Diagnosis of pyogenic granuloma |
| 5 | Treatment of intussusception |
| 6 | Treatment of angioectasia (type 1 small bowel vascular lesions) |
| 7 | Treatment of post-operative bile leakage after hepatico-jejunostomy |
The neuroendocrine tumor exclusion is the one most likely to catch your team off guard. The policy lists carcinoid tumor ICD-10 codes, which might suggest coverage — but Aetna explicitly excludes DBE for neuroendocrine tumor detection. Don't let the presence of those ICD-10 codes in the code table mislead you into thinking the indication is covered.
Aetna also excludes combined DBE and endoscopic ultrasound for Crohn's disease evaluation. If your physician orders a combined DBE-EUS approach for a Crohn's patient, that claim will not meet medical necessity criteria under this policy. Document accordingly and set expectations with your clinical team before the procedure.
Coverage Indications at a Glance
| Indication | Coverage Status | Relevant Codes | Notes |
|---|---|---|---|
| Small bowel stricture dilation in Crohn's disease | Covered | Crohn's ICD-10 codes | Must confirm Crohn's diagnosis in documentation |
| Suspected small bowel malignancy (adenocarcinoma, lymphoma, GIST, metastatic) | Covered | C17.0–C17.9, C78.4, C81.00–C88.91 | Suspicion must be clinically supported |
| Incomplete colonoscopy — colon evaluation | Covered | CPT 45378 | Prior incomplete colonoscopy must be documented |
| Suspected Meckel's diverticulum with inconclusive imaging | Covered | CPT 74176–74178, CPT 78290 | CT or Meckel's scan must be documented as non-diagnostic |
| Obscure GI bleeding with objective evidence | Covered | D50.0–D50.9, D62 | Iron-deficiency anemia, positive FOBT, or visible bleeding required |
| Suspected Crohn's — negative conventional workup | Covered | CPT 91110, 43235, 45378 | Must document negative capsule endoscopy, SBFT, EGD, and colonoscopy |
| Foreign body removal (e.g., retained capsule) | Covered | CPT 91110 | Retained video capsule is the primary example |
| Large polyp removal (>10 mm) in Peutz-Jeghers syndrome | Covered | Peutz-Jeghers diagnosis codes | Polyp size threshold is 10 mm — document size explicitly |
| GI bleeding — small intestine confirmed as source | Covered | D62, D50 range | Source must be identified as small intestinal |
| DBE with ERCP in surgically altered upper GI anatomy | Covered | CPT 43260–43273, C7541–C7544, C7560, CPT 47780, 47785 | Surgical anatomy alteration must be documented |

| Pyogenic granuloma | Experimental | — | Not covered |
| Intussusception treatment | Experimental | — | Not covered |
| Angioectasia treatment (type 1 vascular lesions) | Experimental | — | Not covered |
| Post-operative bile leakage after hepatico-jejunostomy | Experimental | — | Not covered |
| Combined DBE + endoscopic ultrasound for Crohn's | Experimental | — | Excluded even when Crohn's diagnosis supports DBE alone |
Aetna Double Balloon Enteroscopy Billing Guidelines and Action Items 2025
| # | Action Item |
|---|---|
| 1 | Audit your active DBE cases before November 15, 2025. Pull any pending or upcoming DBE procedures and verify the clinical indication matches one of the nine covered indications. If it doesn't, hold the claim and flag it for your compliance officer. |
| 2 | Confirm ICD-10 codes before claim submission. Aetna validates medical necessity through diagnosis codes. For GI bleeding cases, use D50.0–D50.9 for iron-deficiency anemia or D62 for acute posthemorrhagic anemia. For malignancy evaluations, use the appropriate C17 codes. Nonspecific codes or mismatched diagnoses generate denials. |
| 3 | Watch the neuroendocrine tumor trap. If your physician performed DBE to detect a neuroendocrine or carcinoid tumor, don't submit that claim assuming coverage — even if C7A or D3A codes appear valid. Aetna explicitly excludes this indication. Talk to your compliance officer about how to handle these cases, especially if the procedure was already performed. |
| 4 | Document failed prior workup for obscure bleeding and suspected Crohn's cases. Aetna requires evidence that conventional diagnostics — capsule endoscopy (CPT 91110), EGD (CPT 43235), and colonoscopy (CPT 45378) — were negative before DBE is medically necessary for these indications. If that documentation isn't in the chart, your claim is vulnerable. |
| 5 | For Meckel's diverticulum cases, document the CT or scan result explicitly. Aetna requires that imaging — either CT abdomen/pelvis (CPT 74176, 74177, or 74178) or Meckel's scan (CPT 78290) — was inconclusive. "Imaging performed" is not enough. The note should say the result was non-diagnostic and explain why DBE was the next step. |
| 6 | For ERCP plus DBE in altered anatomy, document the surgical history clearly. Roux-en-Y procedures (CPT 47780, 47785) are the primary context here. If the patient's anatomy is altered for any other reason, confirm that reason is in the record and that the DBE was necessary to reach the ampulla. |
| 7 | Check plan-level prior authorization requirements. DBE double balloon enteroscopy billing is high-dollar and draws utilization review. Even if CPB 0737 doesn't mandate prior auth explicitly, individual Aetna plans may require it. Verify before scheduling, not after the procedure is done. |
