Type 1 Excludes
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.

About the N70–N77 Code Range
ICD-10 codes N70 through N77 cover inflammatory diseases affecting various female pelvic organs, such as the fallopian tubes, ovaries, uterus, cervix, vagina, vulva, and Bartholin's glands. These codes are specifically used to classify conditions like salpingitis, oophoritis, pelvic inflammatory disease, and vulvovaginal ulcerations, providing detailed distinctions between acute, chronic, and unspecified cases.
This code range includes conditions such as acute and chronic salpingitis and oophoritis (inflammation of fallopian tubes and ovaries), often referenced with synonyms like tubo-ovarian inflammatory disease (N70 codes). The codes also cover inflammatory diseases of the uterus excluding the cervix, like endometritis and myometritis (N71), as well as inflammation of the cervix uteri, commonly known as cervicitis (N72). Additionally, inflammatory pelvic disorders such as pelvic cellulitis, peritonitis, and adhesions are coded under N73 and related categories. Diseases of Bartholin’s gland—including cysts and abscesses—are categorized under N75. Other specified and unspecified inflammatory conditions of the vagina and vulva, like vaginitis, vulvitis, and ulcerations, are detailed within N76 and N77, with some codes noting involvement due to other systemic diseases such as Behcet’s disease or reactive arthritis. This comprehensive range assists healthcare providers and coders in identifying and documenting female pelvic inflammatory conditions with precision based on symptom duration, location, and severity.

Use Additional Code
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
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.

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.

Type 1 Excludes
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.
The “use additional code” indicates that a secondary code could be used to further specify the patient’s condition. This note is not mandatory and is only used if enough information is available to assign an additional code.
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.
