About N70

N70 is the ICD-10-CM diagnosis code for salpingitis and oophoritis. It belongs to block N70-N77 (inflammatory diseases of female pelvic organs) and chapter 14 (diseases of the genitourinary system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N70.0 (oophoritis), N70.1 (oophoritis) and N70.9 (unspecified).

Don't report N70 together with the conditions in its Excludes1 note: gonococcal infection (A54.24) and tuberculous infection (A18.17).

Use an additional code (B95-B97), to identify infectious agent.

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
