What ICD-10 codes are used for Barrett's esophagus?
Barrett's esophagus is a condition where the normal squamous cells lining the esophagus are replaced by columnar epithelium, often due to chronic acid reflux. This metaplastic change increases the risk of developing esophageal adenocarcinoma. The ICD-10-CM provides specific codes to classify Barrett's esophagus based on the presence and grade of dysplasia:
K22.70 – Barrett's esophagus without dysplasia
This code is used when Barrett's esophagus is diagnosed without any evidence of dysplasia. It represents a condition where columnar epithelium has replaced the normal lining, but no precancerous changes are present.
K22.710 – Barrett's esophagus with low-grade dysplasia
Indicates the presence of low-grade dysplasia, where cells show early precancerous changes. This stage requires careful monitoring and may involve treatment to prevent progression.
K22.711 – Barrett's esophagus with high-grade dysplasia
Denotes high-grade dysplasia, a more advanced precancerous condition with a higher risk of developing into esophageal adenocarcinoma. Prompt and aggressive treatment is often recommended.
K22.719 – Barrett's esophagus with Dysplasia, unspecified
Used when dysplasia is present, but the grade (low or high) has not been specified. Further diagnostic evaluation is typically necessary.
