F91.8
ICD-10-CMThis code represents conduct disorders that do not meet the criteria for other specified conduct disorder subtypes, such as childhood-onset, adolescent-onset, or unspecified. It encompasses a persistent pattern of behavior in which the basic rights of others or major age-appropriate societal norms or rules are violated, but the specific presentation doesn't fit neatly into more defined categories.
Use this code when documentation clearly indicates a conduct disorder diagnosis, but the specific characteristics or onset do not align with other more specific F91 codes. This code is appropriate when the clinician has identified a conduct disorder but has not specified the onset type (e.g., childhood-onset, adolescent-onset) or if the presentation includes features from multiple categories without meeting full criteria for any single one.
