Which MS-DRGs does E44.1 group to?
E44.1 sits in MDC 10 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 640Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes with MCCmedical
- 641Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCCmedical
As a secondary diagnosis, E44.1 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from Chapter 4

- transitory endocrine and metabolic disorders specific to newborn (P70-P74)
Excludes1 — never code together — inherited from E40-E46
The conditions below can never be reported together with E44.1 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Excludes2 — not included here — inherited from E40-E46
The conditions below are not part of E44.1, but a patient may have both at the same time. When documentation supports it, E44.1 and the excluded code may both be reported.
