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.
| 59 | Distinct procedural service | Use when this endoscopic specimen collection is distinct from other endoscopic procedures performed the same day.
| 62 | Two surgeons | Use when two surgeons from different specialties perform separate portions of the procedure.
| 66 | Surgical team | Use when a surgical team performs the procedure in a complex case requiring multiple practitioners.
| 73 | Discontinued outpatient prior to anesthesia | Use when the outpatient procedure is discontinued before administration of anesthesia.
| 74 | Discontinued outpatient after anesthesia | Use when the outpatient procedure is discontinued after anesthesia is administered.
| 76 | Repeat procedure by same physician | Use when the same physician repeats the procedure during the postoperative period (if applicable).
| 78 | Unplanned return to the operating/procedure room by the same physician following initial procedure for a related procedure during the postoperative period | Use when a related repeat endoscopic sampling is required urgently.
| 59 | Distinct procedural service | Use to indicate a distinct and separate service when multiple endoscopic procedures are reported on the same day.
| TC | Technical component | Use when only the technical component is billed (e.g., facility billing for equipment and supplies).
| 26 | Professional component | Use when only the physician interpretation/collection component is billed.

| K22.2 | Achalasia of esophagus | May require endoscopic evaluation with washings to assess mucosal changes or complications.
