Aetna modified CPB 0259 for transjugular intrahepatic portosystemic shunt (TIPSS), effective September 26, 2025. Here's what billing teams need to know.
Aetna, a CVS Health company, updated its TIPSS coverage policy under CPB 0259 in Aetna system, affecting CPT codes 37182 and 37183 for shunt insertion and revision, plus HCPCS codes C1874 and C1875 for PTFE-coated stents. The update refines medical necessity criteria across five covered indications and explicitly covers polytetrafluoroethylene (PTFE)-coated stents. If your team bills TIPSS procedures for Aetna members, the selection criteria now carry more weight than ever — and a missed criterion means a denied claim.

Aetna TIPSS Coverage Criteria and Medical Necessity Requirements 2025
The Aetna TIPSS coverage policy under CPB 0259 ties medical necessity directly to five clinical indications. Meeting one indication alone is not enough. Members must also satisfy a set of selection criteria outlined in the policy appendix. That two-part test — indication plus selection criteria — is where most claims fall apart.
Here are the five indications Aetna covers:
| # | Covered Indication |
|---|---|
| 1 | Bleeding gastric, esophageal, or ectopic varices — including anorectal, intestinal, and stomal varices. This covers CPT 37182 for initial shunt insertion. The relevant ICD-10 codes include I85.01, I85.11 (esophageal varices with bleeding), and I86.4 (gastric varices). Note the explicit carve-out: TIPSS is not covered for prophylaxis of variceal hemorrhage. I85.00 and I85.10 (varices without bleeding) will not support medical necessity here. |
| 2 | Moderate Budd-Chiari syndrome — only when the member has failed to respond to anticoagulation. ICD-10 I82.0 applies, but the policy explicitly excludes sinusoidal obstruction syndrome. Don't confuse the two when coding. |
| 3 | Portal hypertensive gastropathy with recurrent bleeding — only when the member is already on beta-blockers and continues to bleed despite treatment. The relevant ICD-10 is K31.89. This is a step-therapy requirement baked into the medical necessity criteria. Document the beta-blocker trial clearly in your prior authorization submission. |
| 4 | Severe refractory ascites — only in members who are intolerant of repeated large-volume paracentesis. CPT codes 49082 and 49083 appear in the policy as related codes, which signals that Aetna expects to see a documented paracentesis history before TIPSS is considered. Build that history into your records. |
| 5 | Refractory hepatic hydrothorax — coded to J90. Like ascites, this is a last-resort indication. The word "refractory" carries real weight here. Standard hepatic hydrothorax that hasn't failed conservative management does not meet this bar. |
PTFE-coated stents used during TIPSS are covered. Bill HCPCS C1874 (stent with delivery system) or C1875 (stent without delivery system) alongside CPT 37182 or 37183. Missing the stent codes is leaving reimbursement on the table.
Prior authorization requirements for CPB 0259 are not detailed in this policy update, but TIPSS procedures at this complexity level routinely require prior auth under Aetna commercial plans. Confirm authorization requirements for each member's specific plan before the procedure date.
Aetna TIPSS Exclusions and Non-Covered Indications
This policy has clear exclusions, and they carry real claim denial risk.
Prophylaxis of variceal hemorrhage is explicitly not covered. If a member has esophageal varices without active bleeding — I85.00 or I85.10 — TIPSS does not meet medical necessity under this policy. Submit one of those codes as the primary diagnosis and expect a denial.
Sinusoidal obstruction syndrome is excluded from the Budd-Chiari coverage. ICD-10 I82.0 has a notation in the policy: "not covered for sinusoidal obstruction syndrome." If your documentation conflates the two diagnoses, fix it before the claim goes out.
Failure to meet selection criteria is a catch-all exclusion. The appendix criteria act as a gate. Even a textbook-eligible indication gets denied if the patient's clinical picture doesn't satisfy the selection criteria. Make sure the ordering physician's documentation maps directly to those criteria — not just the clinical indication.
Coverage Indications at a Glance
| Indication | Status | Relevant Codes | Notes |
|---|---|---|---|
| Bleeding gastric, esophageal, or ectopic varices | Covered | CPT 37182/37183; I85.01, I85.11, I86.4, I86.8 | Must also meet appendix selection criteria; prophylaxis not covered |
| Moderate Budd-Chiari syndrome, failed anticoagulation | Covered | CPT 37182/37183; I82.0 | Sinusoidal obstruction syndrome explicitly excluded |
| Portal hypertensive gastropathy, recurrent bleeding on beta-blockers | Covered | CPT 37182/37183; K31.89 | Beta-blocker trial must be documented |
| Severe refractory ascites, intolerant of large-volume paracentesis | Covered | CPT 37182/37183; 49082/49083 (related) | Paracentesis history required to establish refractoriness |
| Refractory hepatic hydrothorax | Covered | CPT 37182/37183; J90 | Must document failure of conservative management |
| Prophylaxis of variceal hemorrhage | Not Covered | I85.00, I85.10 | Explicitly excluded regardless of selection criteria |
| Sinusoidal obstruction syndrome | Not Covered | I82.0 (with sinusoidal documentation) | Excluded under Budd-Chiari coverage clause |
| PTFE-coated stents for TIPSS | Covered | C1874, C1875 | Bill alongside primary CPT code |
Aetna TIPSS Billing Guidelines and Action Items 2025
These steps apply now. The effective date is September 26, 2025.
| # | Action Item |
|---|---|
| 1 | Audit all open TIPSS prior auth requests before September 26, 2025. Any prior authorization submitted before the effective date should be reviewed against the updated CPB 0259 criteria. If the clinical documentation doesn't address all five covered indications and the appendix selection criteria, supplement it now. |
| 2 | Update your charge capture to include C1874 or C1875 when PTFE-coated stents are used. These HCPCS codes are explicitly covered under the revised policy. If your current workflow doesn't capture stent type at charge entry, fix the charge description master before the effective date. |
| 3 | Train your coding team on the prophylaxis exclusion. The policy explicitly bars TIPSS billing for variceal hemorrhage prophylaxis. If coders are assigning I85.00 or I85.10 as the primary diagnosis, those claims will deny. The correct covered codes are I85.01 and I85.11 — bleeding varices, not non-bleeding. |
| 4 | Document the step-therapy requirements for ascites and gastropathy. For refractory ascites, you need a documented paracentesis history showing intolerance or failure. For portal hypertensive gastropathy, the record must show active beta-blocker use with ongoing bleeding. These aren't just clinical facts — they're billing criteria. If they're not in the note, the claim fails. |
| 5 | Separate Budd-Chiari from sinusoidal obstruction syndrome in documentation. Both can appear under I82.0, but the policy excludes sinusoidal obstruction syndrome. Make sure the diagnosis documentation is specific. If the distinction isn't clear in the physician's note, get an addendum before billing. |
| 6 | Confirm 37183 revision claims meet selection criteria independently. Revision of a TIPSS (CPT 37183) has the same coverage rules as insertion. Don't assume a previously authorized shunt insertion carries over to revision. Each procedure needs its own medical necessity justification under CPB 0259. |
| 7 | Check plan-level prior authorization requirements. CPB 0259 sets coverage policy, but prior authorization requirements vary by member plan. For high-dollar procedures like TIPSS — where the procedure and stent together represent significant reimbursement — confirm authorization before every case. A claim denial post-procedure is harder to fix than a prior auth gap before it. |
If you're unsure how CPB 0259 applies to your specific patient population or payer mix, talk to your compliance officer before September 26, 2025.
