About N73

N73 is the ICD-10-CM diagnosis code for other female pelvic inflammatory diseases. 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 9 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: N73.0 (cellulitis), N73.1 (cellulitis), N73.2 (cellulitis), N73.3 (peritonitis), N73.4 (peritonitis), N73.5 (unspecified), N73.6 ((postinfective)), N73.8 (diseases) and 1 more.

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.
