What Medicare edits apply to N74?
The Medicare Code Editor screens inpatient claims before they are grouped. These edits name N74 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 N74 group to?
N74 sits in MDC 13 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.
- 742Uterine and Adnexa Procedures for Non-Malignancy with CC/MCCsurgical
- 743Uterine and Adnexa Procedures for Non-Malignancy without CC/MCCsurgical
Excludes1 — never code together
The conditions below can never be reported together with N74 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.
- chlamydial cervicitis (A56.02)
- chlamydial pelvic inflammatory disease (A56.11)
- gonococcal cervicitis (A54.03)
- gonococcal pelvic inflammatory disease (A54.24)
- herpesviral [herpes simplex] cervicitis (A60.03)
- herpesviral [herpes simplex] pelvic inflammatory disease (A60.09)
- syphilitic cervicitis (A52.76)
- syphilitic pelvic inflammatory disease (A52.76)
- trichomonal cervicitis (A59.09)
- tuberculous cervicitis (A18.16)
- tuberculous pelvic inflammatory disease (A18.17)
Code first
The underlying condition below must be sequenced before N74. N74 describes a manifestation and cannot be the principal or first-listed diagnosis.
- underlying disease
Excludes1 — never code together — inherited from N70-N77
The conditions below can never be reported together with N74 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 Chapter 14
The conditions below are not part of N74, but a patient may have both at the same time. When documentation supports it, N74 and the excluded code may both be reported.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
Code also — inherited from N70-N77
Two codes may be needed to describe the condition fully. Whether N74 is sequenced first depends on the reason for the encounter.
- , if applicable, pelvic abscess (K6A.0-)
How long has N74 existed?
N74 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.
Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
