N73.5 is a billable ICD-10 code used to specify a medical diagnosis of female pelvic peritonitis, unspecified. The code is valid during the fiscal year 2023 from October 01, 2022 through September 30, 2023 for the submission of HIPAA-covered transactions.

This code is applicable to female patients only. It is clinically and virtually impossible to use this code on a non-female patient.

Unspecified diagnosis codes like N73.5 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
