Documentation tips

Make sure the note supports every element of the title, “Blood alcohol level of 100-119 mg/100 ml”: each detail in it should be traceable to the history, examination or assessment.
Code to the highest specificity the documentation supports. If a detail is missing from the note, add it to the note rather than choosing a less specific code by default.
Check the Tabular List and official guidelines for instructional notes (“code first”, “use additional code”, Excludes1/Excludes2) that apply to Y90.

The international WHO ICD-10 also has Y90.5, with its inclusion and exclusion notes; titles and detail can differ from ICD-10-CM.

ICD-10-CM is developed by the National Center for Health Statistics (NCHS), Centers for Disease Control and Prevention, U.S. Department of Health and Human Services, and is based on the WHO ICD-10. Codes and titles are reproduced unchanged from the FY2026 code list (effective 1 October 2025). Their use here does not imply endorsement by CDC, HHS or the U.S. Government. Changes effective on or after 1 October 2026 may not be reflected yet; check the current release at cdc.gov or cms.gov before submitting claims.
