Evidence of alcohol involvement determined by blood alcohol level (Y90) ICD-10-CM
The Y90 code range covers evidence of alcohol involvement determined by blood alcohol level with 11 ICD-10-CM diagnosis codes. 10 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Code First
Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.

About the Y90 Code Range
The ICD-10 code Y90 series is used to document evidence of alcohol involvement based on measured blood alcohol levels. These codes specify exact alcohol concentrations in the blood, ranging from less than 20 mg/100 ml to 240 mg/100 ml or more, helping to categorize the extent of alcohol presence.
Each specific code from Y90.0 to Y90.8 identifies a particular blood alcohol level range, providing precise external cause details related to alcohol involvement. For example, Y90.0 indicates a blood alcohol level under 20 mg/100 ml, while Y90.8 denotes levels at or above 240 mg/100 ml. When the exact level is unknown but alcohol is detected, Y90.9 is the appropriate code; this code is also linked with terms like “finding of alcohol in blood,” “high ethanol level in blood,” or “high alcohol level in blood.” Medical coders can use this section to translate laboratory blood alcohol test results into accurate ICD-10 codes, ensuring detailed documentation of alcohol involvement for clinical, legal, or insurance purposes.
