Obesity class codes

Official text from the FY2027 ICD-10-CM Official Guidelines for Coding and Reporting. The wording is quoted exactly.

Guidelines I.C.4.b.1

“The obesity class should be documented in the medical record by the provider for these codes to be assigned.”

“However, if both class 3 obesity and morbid obesity are documented, only a code for class 3 obesity should be assigned as it is more specific.”
