    ICD-10-CM Code For Other Female Pelvic Inflammatory Diseases: Group Overview

    The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) code group N73 includes inflammatory diseases of female pelvic organs that are not classified elsewhere, such as unspecified pelvic inflammatory disease and other specified inflammatory disorders of the uterus, fallopian tubes, and adnexa. These ICD-10-CM diagnosis codes are used to document presentations of pelvic inflammation, capturing organ involvement, extent of disease, and any associated complications or unspecified severity. Accurate coding within the ICD-10-CM N73 group supports proper claim adjudication, complete clinical documentation, and appropriate reimbursement.

    ICD-10-CM N73: Other Female Pelvic Inflammatory Diseases Overview

    The ICD-10-CM N73 group represents inflammatory conditions affecting the female pelvic organs that do not fall into more specific pelvic inflammatory disease subgroups. These diagnoses target structures such as the uterus, fallopian tubes, and surrounding pelvic tissues. Accurate coding is important to reflect clinical severity and support appropriate reimbursement.

    When to Use

    Use a code from this group when a patient presents with pelvic inflammatory symptoms or signs attributed to female pelvic organs and the condition does not meet criteria for a more specific ICD-10-CM pelvic inflammatory disease code. These codes apply when documentation specifies an unspecified or other specified inflammatory disorder of the uterus, fallopian tubes, or adnexa.

    Typical Clinical Scenarios

    • A 24-year-old sexually active woman presents to the emergency department with acute onset lower abdominal pain, high fever, purulent vaginal discharge, and cervical motion tenderness after several days of worsening symptoms. Pelvic examination and pelvic ultrasound suggest adnexal tenderness and possible tubo-ovarian inflammation consistent with an acute pelvic inflammatory process; a diagnosis from this group is assigned to capture an acute inflammatory disease of the upper female reproductive tract likely due to ascending infection. Typical codes: N73.0, N73.1
    • A 36-year-old woman with a history of recurrent cervicitis reports months of chronic, diffuse pelvic pain, dyspareunia, and intermittent abnormal vaginal bleeding despite prior courses of antibiotics. Evaluation documents chronic inflammatory changes of the uterus and adnexa with scarring and persistent symptoms over several months, prompting assignment of a chronic inflammatory pelvic diagnosis from this group to reflect long-standing pelvic organ inflammation. Typical codes: N73.2, N73.6
    • A 42-year-old patient is admitted for management of infertility and imaging reveals bilateral hydrosalpinx and adhesions thought to be a sequela of prior pelvic infections; she denies acute fever or purulent discharge but has chronic pelvic discomfort. Because the presentation represents a complication of prior pelvic inflammatory disease with residual inflammatory damage to the fallopian tubes and pelvic organs, a code from this group is used to document the pelvic inflammatory disease as a contributing comorbidity to her infertility. Typical codes: N73.3, N73.5
