About N74

N74 is the ICD-10-CM diagnosis code for female pelvic inflammatory disorders in diseases classified elsewhere. It belongs to block N70-N77 (inflammatory diseases of female pelvic organs) and chapter 14 (diseases of the genitourinary system). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Don't report N74 together with the conditions in its Excludes1 note: chlamydial cervicitis (A56.02), chlamydial pelvic inflammatory disease (A56.11), gonococcal cervicitis (A54.03), gonococcal pelvic inflammatory disease (A54.24) and 7 more.

Code first: underlying disease.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC, relative weight 1.8456), DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC, relative weight 1.2974), DRG 757 (Infections, Female Reproductive System with MCC, relative weight 1.4649), DRG 758 (Infections, Female Reproductive System with CC, relative weight 0.9908) and DRG 759 (Infections, Female Reproductive System without CC/MCC, relative weight 0.7691), in MDC 13 (Diseases and Disorders of the Female Reproductive System), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.

It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

It is on the CMS list of diagnoses consistent only with female patients (the sex-conflict edit itself was retired in FY2025).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.

Before ICD-10, this condition was coded in ICD-9-CM as 614.8 (other specified inflammatory disease of female pelvic organs and tissues).

Yes. N74 is a billable/specific ICD-10-CM code valid for FY2027 (October 1, 2026 – September 30, 2027).

Can N74 be used as a principal diagnosis?

No. It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.

Is N74 a CC or MCC?

No. N74 is neither a CC nor an MCC under MS-DRG v44.0.

What DRG does N74 group to?

N74 is used in the MS-DRG v44.0 logic for MS-DRG 742 (Uterine and Adnexa Procedures for Non-Malignancy with CC/MCC), MS-DRG 743 (Uterine and Adnexa Procedures for Non-Malignancy without CC/MCC), MS-DRG 757 (Infections, Female Reproductive System with MCC), MS-DRG 758 (Infections, Female Reproductive System with CC) and MS-DRG 759 (Infections, Female Reproductive System without CC/MCC). Which one applies depends on whether it is the principal diagnosis and on the rest of the claim.

What is the ICD-9 code for N74?

The CMS General Equivalence Mappings map N74 to ICD-9-CM 614.8.
