  • N72 is billable and valid on claims for FY 2027. If the record has more detail, check the other codes under N70-N77 below.
  • As a secondary diagnosis it is not a CC or MCC, so it doesn't raise the MS-DRG payment.
  • Doesn't count toward a Medicare Advantage risk score (no HCC in V28).
  • AHRQ's Chronic Condition Indicator classes it as not chronic (an acute or short-term condition).

Also indexed as: Cervicitis; Cervicocolpitis; Ectropion, cervix, with cervicitis; Endocervicitis, hyperplastic; Endometritis, cervix, cervical, hyperplastic; Endometritis, hyperplastic, cervix; Erosion, cervix, with cervicitis; Eversion, cervix, with cervicitis; Hyperplasia, endocervicitis; Ulcer, cervix, with cervicitis; Ulcer, uterus, cervix, with cervicitis; Ulcer, uterus, neck, with cervicitis

Cervix Disorders

A cervix disorder is a problem with your cervix. The cervix is part of the female reproductive system. It is the lower, narrow end of the uterus (womb), which opens into the vagina (birth canal). The cervix has a small opening that expands during childbirth. It also allows menstrual blood to leave your body.
