Code Also
A "code also" note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.
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
These conditions affect female pelvic organs, including the uterus, cervix, vagina and vulva. The group also includes cysts and abscesses of Bartholin's gland.
N70 groups inflammation of the fallopian tubes and ovaries as acute, chronic or unspecified. N71 makes the same distinction for inflammation of the uterus, except the cervix. N72 identifies inflammation of the cervix.
N73 separates other pelvic inflammatory conditions by type and, for some conditions, acute or chronic status. N74 identifies pelvic inflammatory disorders in diseases classified elsewhere. N75 distinguishes cysts, abscesses and other diseases of Bartholin's gland.
N76 separates vaginal and vulvar conditions by site and type, including inflammation, abscesses and ulcers. Its inflammation subdivisions distinguish acute from subacute or chronic conditions. N77 identifies vulvar ulcers and vaginal or vulvar inflammation in diseases classified elsewhere.

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.
