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.
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.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the N70 range.
Acute Salpingitis
Acute inflammation of the fallopian tube. It is most often caused by Neisseria gonorrhoeae and Chlamydia trachomatis infections. The infections usually originate in the vagina and ascend to the fallopian tube. Symptoms include abdominal, pelvic, and lower back pain, pain during ovulation and sexual intercourse, fever, nausea, and vomiting. Complications include infertility and ectopic pregnancy.
Chronic Salpingitis
Chronic inflammation of the fallopian tube. It usually follows an acute inflammatory attack.
Oophoritis
Inflammation of the OVARY, generally caused by an ascending infection of organisms from the endocervix.
Salpingitis
Inflammation of the uterine salpinx, the trumpet-shaped FALLOPIAN TUBES, usually caused by ascending infections of organisms from the lower reproductive tract. Salpingitis can lead to tubal scarring, hydrosalpinx, tubal occlusion, INFERTILITY, and ectopic pregnancy (PREGNANCY, ECTOPIC)
About the N70 Code Range
Salpingitis means inflammation of a fallopian tube, while oophoritis means inflammation of an ovary. Either can occur alone or with the other.
The subdivisions group these conditions as acute under N70.0, chronic under N70.1, or unspecified under N70.9. Within each group, separate codes identify salpingitis alone, oophoritis alone, or both together.
