Barrett's esophagus with high grade dysplasia

This code signifies a severe progression of Barrett's esophagus, characterized by significant precancerous cellular changes in the esophageal lining. High-grade dysplasia indicates a high likelihood of developing into esophageal adenocarcinoma if left untreated. This condition is typically identified through endoscopic biopsy.

Assign this code when documentation explicitly states a diagnosis of Barrett's esophagus with high-grade dysplasia. This diagnosis is usually confirmed by pathology reports following an upper endoscopy with biopsies. It is crucial to differentiate this from low-grade dysplasia or Barrett's without dysplasia.

• Ensure the pathology report specifically identifies "high-grade dysplasia" in the context of Barrett's esophagus.
• Do not use this code for low-grade dysplasia (K22.701) or Barrett's esophagus without dysplasia (K22.700).
• If esophageal adenocarcinoma is also present, code the malignancy first, followed by this code as an associated condition.
