Surgical Procedures – Medicare Advantage Medical Policy | UHC Coverage Update

TL;DR: UnitedHealthcare modified its Surgical Procedures coverage policy, effective March 2, 2026, consolidating medical necessity criteria across bariatric surgery, bronchial thermoplasty, hiatal hernia repair, glaucoma drainage device implantation, and lymphedema surgical treatments under one policy framework. Here's what billing teams need to do.

This update touches 50 CPT codes spanning five surgical categories — from bariatric procedures like sleeve gastrectomy (CPT 43775) and Roux-en-Y gastric bypass (CPT 43644, 43645) to lymphedema excision codes (CPT 15830–15839) and glaucoma shunting (CPT 66180). The UnitedHealthcare surgical procedures coverage policy explicitly routes Medicare Advantage billing through NCD, LCD, and LCA hierarchies before falling back to commercial policy guidance. If your team bills any of these procedures for Medicare Advantage members, the framework governing your claims just got a formal update.

UnitedHealthcare Surgical Procedures Coverage Criteria and Medical Necessity Requirements 2026

The real issue here is hierarchy. UnitedHealthcare's updated surgical procedures coverage policy for Medicare Advantage doesn't set its own medical necessity criteria — it directs you to the right source depending on what coverage exists at the national and local level.

Here's how that hierarchy works for each category:

Bariatric Surgery runs through NCD 100.1 first. That's the National Coverage Determination for Bariatric Surgery for Treatment of Co-Morbid Conditions Related to Morbid Obesity. If an LCD or LCA exists in your state, you must comply with it. Check the policy's table for Bariatric Surgical Management of Morbid Obesity to find your applicable LCD or LCA.

If your state has no LCD or LCA, fall back to the UnitedHealthcare Commercial Medical Policy for Bariatric Surgery. This applies to all procedures not listed as nationally non-covered under NCD 100.1. That includes revision procedures, staged procedures, and endoscopic approaches like endoscopic sleeve gastroplasty (CPT 43889). When the NCD and LCDs are silent on a specific approach, the commercial medical policy fills the gap.

Bronchial thermoplasty has no NCD and no LCDs or LCAs as of this update. Coverage guidelines come entirely from the UnitedHealthcare Commercial Medical Policy for Bronchial Thermoplasty. CPT 31660 and 31661 are the codes at stake here. Review that commercial policy for all coverage requirements before scheduling.

Hiatal hernia repair also has no NCD and no LCDs or LCAs. Coverage guidelines route to InterQual CP: Procedures, Antireflux Surgery or Hiatal Hernia Repair. CPT 43499 is the unlisted esophagus code you'll use here. InterQual criteria are criteria-based and reviewable — your team needs access to those criteria before submitting claims.

Glaucoma drainage device implantation has no NCD and no LCDs or LCAs — specifically for CPT 66180 (aqueous shunt to extraocular equatorial plate reservoir, external approach with graft). Coverage guidelines fall to the UnitedHealthcare Commercial Medical Policy for Glaucoma Surgical Treatments.

Lymphedema surgical treatments have no NCD and no LCDs or LCAs. Coverage guidelines follow the UnitedHealthcare Commercial Medical Policy for Surgery for the Prevention and Treatment of Lymphedema. The affected codes span excision procedures (CPT 15830–15839, 15847) and suction-assisted lipectomy (CPT 15876–15879), plus unlisted hemic or lymphatic procedure code CPT 38999.

The medical necessity determination for all five categories flows from the top of this hierarchy down. Knowing where your procedure lands — NCD, LCD, commercial policy, or InterQual — determines what documentation you need before you bill.
