Summary & Overview
CPT 43200: Endoscopic Brushing or Washing for Cytologic Specimens
Headline: CPT code 43200 outlines endoscopic collection of cellular specimens via brushing or washing through the mouth. Lead: CPT code 43200 defines a diagnostic endoscopic procedure in which a flexible endoscope is passed orally to obtain specimens by brushing or washing for pathologic analysis. This code is widely used across inpatient and outpatient endoscopy settings and is relevant to gastroenterology, pathology, and payer coverage policies.
CPT code 43200 represents a focused diagnostic technique to obtain cytology specimens during upper endoscopy. It matters nationally because cytologic sampling can guide diagnosis and management of esophageal, gastric, and duodenal lesions without requiring immediate tissue biopsy. Coverage and reimbursement policies for specimen-collection procedures affect procedural coding, documentation, and clinical workflows across health systems.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the code’s clinical role, typical sites of service, and the payer landscape. The publication summarizes common billing considerations, standard modifiers used with diagnostic endoscopic specimen collection, and implications for documentation and pathology submission.
What readers will learn: concise benchmarks for utilization and reimbursement contexts (where available), policy and coding guidance highlights, and clinical context for when brushing or washing is selected over other sampling methods. Data not available in the input will be identified as such.
Billing Code Overview
CPT code 43200 describes a diagnostic procedure in which a provider passes a flexible endoscope through the mouth to collect specimens by brushing or washing for pathologic analysis. This procedure is a form of esophagogastroduodenoscopy (EGD) with brushings/washings for cytology, used to obtain cellular material when visual inspection alone is insufficient.
Service type: Endoscopic diagnostic specimen collection (brushing/washing)
Typical site of service: Endoscopy suite or ambulatory surgical center; may also be performed in a hospital inpatient setting when clinically indicated.

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult presenting with persistent dysphagia, odynophagia, unexplained weight loss, or an upper aerodigestive tract lesion seen on imaging or laryngoscopy. The otolaryngologist or gastroenterologist performs a flexible transoral endoscopy (esophagoscopy/bronchoscopy/pharyngoscopy depending on indication) under topical anesthesia with or without sedation to obtain cytologic or pathologic specimens by brushing or washing for evaluation of infection, inflammation, or malignancy. The workflow includes pre-procedure assessment, informed consent, topical anesthesia and optional moderate sedation, insertion of the flexible endoscope through the mouth to the target area, collection of specimens by brushings or washings, labeling and submission to pathology/microbiology, and post-procedure monitoring before discharge to home or admission if clinically indicated.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
26 | Professional component | Use when reporting only the physician professional portion of a dual component service if applicable. |
| 52 | Reduced services | Use when the procedure is partially reduced or not completed as planned.
| 53 | Discontinued procedure | Use when the procedure is started but terminated due to extenuating circumstances.
