Summary & Overview
CPT 43235: Diagnostic EGD with Brushing/Washing
Headline: CPT 43235: Diagnostic EGD with Brushing/Washing Gains Clinical and Billing Focus
Lead: CPT 43235 identifies a diagnostic esophagogastroduodenoscopy (EGD) performed transorally with specimen collection by brushing or washing, a commonly used technique to evaluate upper gastrointestinal complaints and obtain cytologic samples.
What the code represents and why it matters: CPT 43235 is the billing code for a diagnostic upper endoscopy using brushing or washing to collect specimens. Nationally, this code matters because EGD is a high-volume procedure across outpatient settings and contributes to clinical decision-making for conditions such as reflux, gastritis, ulcers, and unexplained upper abdominal symptoms. Accurate coding affects quality measurement, claims processing, and appropriate capture of diagnostic procedures.
Key payers covered: The analysis addresses major commercial and public payers including Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
What readers will learn: The publication provides benchmarks for utilization and coding practice, clarifies clinical context for use of brushing/washing specimen collection during EGD, and outlines common adjunct codes and coding considerations tied to the procedure. It also highlights typical site-of-service implications and how this code relates to nearby endoscopic codes used for biopsy, dilation, lesion removal, and endoscopic ultrasound.
Scope and limitations: Service line metadata is not available in the input. Data not available in the input where specific utilization or reimbursement metrics would otherwise be expected.
CPT Code Overview
CPT 43235 describes a flexible transoral esophagogastroduodenoscopy performed for diagnostic purposes with collection of specimen(s) by brushing or washing. This procedure involves endoscopic visualization of the esophagus, stomach, and duodenum to evaluate upper gastrointestinal symptoms and obtain cytologic samples via brushing or lavage for laboratory analysis.
Service Type: Esophagogastroduodenoscopy Procedures
Typical Site of Service: Outpatient Hospital (POS 22)
Clinical & Coding Specifications
A middle-aged outpatient presents to the gastroenterology clinic with several weeks of epigastric pain, intermittent nausea, and reflux symptoms unresponsive to empirical therapy. The patient is scheduled for an outpatient hospital esophagogastroduodenoscopy (EGD) to evaluate the esophagus, stomach, and proximal duodenum. The procedure is performed using a flexible transoral endoscope under moderate sedation. During the diagnostic EGD, the endoscopist performs thorough mucosal inspection and collects cellular material by brushing or washing for cytologic analysis when indicated (e.g., to evaluate suspicious mucosal irregularity or to obtain cytology for evaluation of Barrett-type changes or infectious/inflammatory processes). The typical clinical workflow includes pre-procedure consent and history review, sedation administered by qualified personnel, performance of the 43235 procedure with specimen collection by brushing or washing, recovery and post-procedure instructions, and transmission of specimens to pathology or cytology for interpretation.
Modifiers:
-
26(Professional Component): Use when reporting only the physician’s professional interpretation or services for the procedure separate from the facility/technical component. -
51(Multiple Procedures): Use when43235is performed in the same session with other unrelated endoscopic procedures; applies when payer policy requires reduction for additional procedures performed the same day. -
59(Distinct Procedural Service): Use when43235is a distinct procedure from another service on the same day that is not normally performed together and meets documentation criteria for separate reporting.
