Official Coding Guidelines

Dementia classified by etiology/severity; code per provider documentation

The ICD-10-CM classifies dementia (categories F01, F02, and F03) on the basis of the etiology and severity (unspecified, mild, moderate or severe). Selection of the appropriate severity level requires the provider’s clinical judgment and codes should be assigned only on the basis of provider documentation (as defined in the Official Guidelines for Coding and Reporting), unless otherwise instructed by the classification.
