Q93 — Monosomies and deletions from the autosomes, not elsewhere classified
Is Q93 billable?
No — Q93 is a non-billable header code. Q93 groups more specific codes and cannot be submitted on a claim. A valid ICD-10-CM code must be reported at the highest level of specificity available in its branch. Select one of the 14 billable codes beneath Q93.

How long has Q93 existed?
Q93 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
