- Billable — Valid for Submission
- CC — Complication or Comorbidity
- POA Exempt
- Chronic Condition
Q93.89 is a billable ICD-10-CM diagnosis code for other deletions from the autosomes. It is valid on HIPAA claims for fiscal year 2027 (October 1, 2026 through September 30, 2027) and groups to MS-DRG 884. As a secondary diagnosis, it counts as a complication or comorbidity (CC) and moves an inpatient stay to a higher severity level within its MS-DRG family. It does not count, however, when the principal diagnosis is one of 61 closely related codes. The code is exempt from POA reporting. In AHRQ's Clinical Classifications Software (CCSR), this diagnosis falls under Chromosomal abnormalities.
Q93.89 does not risk-adjust for Medicare Advantage under the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 148 for payment year 2027.

- Deletions seen only at prometaphase
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

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
What is the ICD-10 code for other deletions from the autosomes?
The ICD-10-CM code for other deletions from the autosomes is Q93.89 (sometimes written as Q9389). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
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, 2026 through September 30, 2027.
What MS-DRG does Q93.89 group to?
When other deletions from the autosomes is the principal diagnosis on an inpatient stay, it groups to MS-DRG 884 (organic Disturbances and Intellectual Disability), which carries a relative weight of 1.5998. Higher weights mean higher Medicare reimbursement.
Is Q93.89 a CC or MCC?
CMS lists Q93.89 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 61 closely related codes in its exclusion list.
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. The code appears in the Chromosomal abnormalities, not elsewhere classified (Q90-Q99) range of the CMS exempt list.
Does Q93.89 risk-adjust for Medicare Advantage payment?
Not for Medicare Advantage: Q93.89 maps to no category in the CMS-HCC V28 model. It still risk-adjusts in the RxHCC Part D (V08) category 148 (Mild or Unspecified Intellectual Disability/Developmental Disorder).
