Which MS-DRGs does H05.031 group to?
H05.031 sits in MDC 02 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.
- 121Acute Major Eye Infections with CC/MCCmedical
- 122Acute Major Eye Infections without CC/MCCmedical
As a secondary diagnosis, H05.031 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

Excludes1 — never code together — inherited from H05
The conditions below can never be reported together with H05.031 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- congenital malformation of orbit (Q10.7)
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H05.031, but a patient may have both at the same time. When documentation supports it, H05.031 and the excluded code may both be reported.
