How coders use this code
ICD-10-CM Q85 is a category (header) for phakomatoses, not elsewhere classified. It is generally not reported directly on a claim — coders drill down to a more specific child code (one with additional characters) that matches the documentation. Use the related codes below to find the billable code that fits, and verify against the annual NCHS/CMS guidelines.
