Other Useful ICD-10 Codes for Mental Health

While insurers prefer descriptive ICD-10 codes, there are times when a clinician needs more information about a patient to support a more specific diagnosis. In these cases, using the code for altered mental status may be acceptable.

R41.82: Altered mental status describes a marked change in mental health status that is not attributable to other factors.

Learn more about when and when not to use the R41.82 diagnostic code here.
