Coverage stanceInvestigational / Not covered

Scope summaryCapital BlueCross medical policy addressing confocal laser endomicroscopy (CLE) across GI and non-GI indications; provides coverage stance, rationale, coding, and references and applies to certain products/programs with benefit variations.

Use of confocal laser endomicroscopy is considered investigational.

Medical Necessity / Coverage Determination

Coverage Determination

Use of confocal laser endomicroscopy is considered investigational.

ALL of the following

Insufficient evidence: There is insufficient evidence to support a general conclusion concerning the health outcomes or benefits associated with confocal laser endomicroscopy (CLE).
Coverage conclusion: Therefore CLE is considered investigational and not covered.

Coding note: Investigational; therefore not covered: 0397T (CLE procedure) and related procedure codes such as 43206, 43252, 88375 (claims for CLE may be denied unless member benefit plan provides coverage).

Not Covered / Investigational Statement

Use of confocal laser endomicroscopy (CLE) is considered investigational and therefore not covered. The policy states there is insufficient evidence to support a general conclusion concerning the health outcomes or benefits associated with CLE; benefit determinations depend on the applicable member health benefit plan language.

Coding

Investigational; therefore not coveredmixedNot Covered

0397T	Confocal laser endomicroscopy procedure (proprietary CPT Category III for CLE)
43206	Esophagoscopy, flexible, transoral; with directed submucosal injection, any solution (listed here paired with 0397T in coding table)
43252	Esophagogastroduodenoscopy, flexible, transoral; with biopsy, single or multiple
88375	Special staining, gross and microscopic examination related code listed in coding table

Because CLE is considered investigational by this policy, claims billed with the identified CLE procedure codes may be denied unless the member's benefit plan language provides coverage.

Provider Actions / Billing Impact

Documentation Required

Benefit verification required

Verify member's specific health benefit plan language because existence of this medical policy does not imply the service is a covered benefit; benefit determinations are based on the applicable health benefit plan.

Denial Risk

Claims for CLE are at risk of denial

Because CLE is considered investigational by this policy, claims billed with the identified CLE procedure codes may be denied unless member benefit plan language provides coverage.

Background, Evidence, and Definitions

Confocal laser endomicroscopy (CLE) is an in vivo microscopic imaging technique performed during endoscopy using a low‑power laser and confocal optics to visualize mucosal cellular structure; FDA‑cleared systems include endoscope‑based and probe‑based devices. Reported applications include characterization of colorectal lesions, Barrett esophagus surveillance, targeting biopsies, and investigational uses in lung, bladder, gastric, pancreatic, biliary, head and neck, and central nervous system lesions. Limitations noted in the policy include a limited viewing area and depth of view, variable lesion classification systems, and a learning curve for image acquisition and interpretation.
