Which MS-DRGs does QA0.011 group to?

QA0.011 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, QA0.011 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes2 — not included here — inherited from Chapter 17

The conditions below are not part of QA0.011, but a patient may have both at the same time. When documentation supports it, QA0.011 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 QA0.011 is sequenced first depends on the reason for the encounter.
