What Medicare edits apply to N37?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name N37 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 N37 group to?
N37 sits in MDC 11 and helps define the logic of 1 MS-DRG (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

Excludes1 — never code together
The conditions below can never be reported together with N37 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
The underlying condition below must be sequenced before N37. N37 describes a manifestation and cannot be the principal or first-listed diagnosis.
- underlying disease
Excludes2 — not included here — inherited from Chapter 14
The conditions below are not part of N37, but a patient may have both at the same time. When documentation supports it, N37 and the excluded code may both be reported.

- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)

Excludes2 — not included here — inherited from N30-N39
The conditions below are not part of N37, but a patient may have both at the same time. When documentation supports it, N37 and the excluded code may both be reported.
