Which MS-DRGs does Q45.3 group to?
Q45.3 sits in MDC 07 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.
- 438Disorders of Pancreas Except Malignancy with MCCmedical
- 439Disorders of Pancreas Except Malignancy with CCmedical
- 440Disorders of Pancreas Except Malignancy without CC/MCCmedical
As a secondary diagnosis, Q45.3 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 Q45.3, but a patient may have both at the same time. When documentation supports it, Q45.3 and the excluded code may both be reported.
- inborn errors of metabolism (E70-E88)
Excludes2 — not included here — inherited from Q45
The conditions below are not part of Q45.3, but a patient may have both at the same time. When documentation supports it, Q45.3 and the excluded code may both be reported.
