Salpingitis and oophoritis (N70) ICD-10-CM
The N70 code range covers salpingitis and oophoritis with 13 ICD-10-CM diagnosis codes. 9 of them are billable and valid for claim submission in fiscal year 2026, and the category headers group them but cannot themselves be billed.
Includes
This note appears immediately under a three character code title to further define, or give examples of, the content of the category.
- abscess (of) fallopian tube
- abscess (of) ovary
- pyosalpinx
- salpingo-oophoritis
- tubo-ovarian abscess
- tubo-ovarian inflammatory disease
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.
Oophoritis
Inflammation of the OVARY, generally caused by an ascending infection of organisms from the endocervix.
Ovary
The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE.
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
The ICD-10 code N70 and its subcodes classify various forms of salpingitis and oophoritis, which are inflammatory conditions of the fallopian tubes and ovaries. These codes help specify whether the inflammation is acute, chronic, or unspecified and identify the exact organs affected.
The main category, N70, covers inflammation of the female pelvic reproductive organs, focusing on the fallopian tubes (salpingitis) and ovaries (oophoritis). For example, N70.01 codes for acute salpingitis, known also as subacute salpingitis, while N70.02 covers acute oophoritis. Combinations of these inflammations, such as acute salpingitis and oophoritis, are coded under N70.03 with synonyms like tubo-ovarian inflammatory disease. Chronic forms, such as hydrosalpinx or salpingitis follicularis, fall under codes like N70.11 for chronic salpingitis. When details are lacking, unspecified codes like N70.91 for unspecified salpingitis and N70.92 for unspecified oophoritis are used. These codes guide precise documentation for conditions including fallopian tube infection, pelvic inflammatory disease, and related abscesses.
