Genetic Disorders

Genetic disorders are health conditions caused by changes (also called mutations or variants) in your genes. Genes are parts of DNA found in your cells that carry instructions for how your body grows, develops, and functions. Many genes tell your body how to make proteins, which are needed for your body to work properly.

Questions About Q93.89Overview

Is Q93.89 (Other deletions from the autosomes) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report other deletions from the autosomes on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

Is Q93.89 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for other deletions from the autosomes on inpatient claims.

What is the ICD-9 equivalent of Q93.89?

Under the General Equivalence Mappings, other deletions from the autosomes converts to ICD-9-CM 758.39 (autosomal deletions NEC). The mapping is approximate, so confirm the match fits the documentation.
