Which MS-DRGs does QA0.8 group to?
QA0.8 sits in MDC 08 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 564Other Musculoskeletal System and Connective Tissue Diagnoses with MCCmedical
- 565Other Musculoskeletal System and Connective Tissue Diagnoses with CCmedical
- 566Other Musculoskeletal System and Connective Tissue Diagnoses without CC/MCCmedical
As a secondary diagnosis, QA0.8 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
How is QA0.8 listed in the Alphabetic Index?
These are the routes through the Alphabetic Index that lead to QA0.8. They show the wording a clinician may have documented, which often differs from the Tabular description.
- Disorder › neurodevelopmental › specified NEC › related to pathogenic variants in specific genes NEC (of)
Excludes2 — not included here — inherited from Chapter 17
The conditions below are not part of QA0.8, but a patient may have both at the same time. When documentation supports it, QA0.8 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
Code also — inherited from QA0
Two codes may be needed to describe the condition fully. Whether QA0.8 is sequenced first depends on the reason for the encounter.
How long has QA0.8 existed?
QA0.8 first appears in FY2026.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
