What Medicare edits apply to H36.89?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name H36.89 directly.
This code describes a manifestation of an underlying disease. The underlying condition must be sequenced before it, so it can never be the principal or first-listed diagnosis.
Which MS-DRGs does H36.89 group to?
H36.89 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.

Excludes1 — never code together — inherited from H36
The conditions below can never be reported together with H36.89 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
Code first — inherited from H36
The underlying condition below must be sequenced before H36.89. H36.89 describes a manifestation and cannot be the principal or first-listed diagnosis.
Excludes2 — not included here — inherited from Chapter 7
The conditions below are not part of H36.89, but a patient may have both at the same time. When documentation supports it, H36.89 and the excluded code may both be reported.
