Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the ICD-10-CM has a coding convention that requires the underlying condition be sequenced first followed by the manifestation. Wherever such a combination exists, there is a "use additional code" note at the etiology code, and a "code first" note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes, etiology followed by manifestation.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

Pelvic Inflammatory Disease
Pelvic inflammatory disease (PID) is an infection of the uterus, ovaries, and other female reproductive organs. PID causes scarring in these organs. This can lead to infertility, ectopic pregnancy, pelvic pain, abscesses (a collection of pus), and other serious problems.

Questions About N74Overview
Is N74 a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report female pelvic inflammatory disorders in diseases classified elsewhere on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does N74 group to?
On inpatient claims, female pelvic inflammatory disorders in diseases classified elsewhere maps to MS-DRG 742, 743, 757, 758, 759, with relative weights from 0.6636 to 1.8348 depending on complications. Higher weights mean higher Medicare reimbursement.
Can N74 be a principal diagnosis?
No. This is a manifestation code: female pelvic inflammatory disorders in diseases classified elsewhere describes the manifestation of an underlying disease rather than the disease itself, so the underlying condition is sequenced first.
What is the ICD-9 equivalent of N74?
Under the General Equivalence Mappings, female pelvic inflammatory disorders in diseases classified elsewhere converts to ICD-9-CM 614.8 (fem pelv inflam dis NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
