AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
Broad Ligament
a broad fold of peritoneum that extends from the side of the uterus to the wall of the pelvis.Internal Hernia
a protrusion of an internal abdominal organ through a hole in an anatomical structure such as a muscle or a membrane. for instance, in paraduodenal hernia the small intestine herniates through an opening in the mesenteries. it includes intra-abdominal and diaphragmatic hernias. in abdominal hernia a protrusion occurs through a weak spot in the muscle of the abdominal wall.Clitoris
an erectile structure homologous with the penis, situated beneath the anterior labial commissure, partially hidden between the anterior ends of the labia minora.Pudendal Nerve
a nerve which originates in the sacral spinal cord (s2 to s4) and innervates the perineum, the external genitalia, the external anal sphincter and the external urethral sphincter. it has three major branches: the perineal nerve, inferior anal nerves, and the dorsal nerve of penis or clitoris.

Ovarian Disorders
The ovaries are a pair of female reproductive glands that make eggs and female hormones. Women have one ovary on each side of the uterus (where a fetus grows during pregnancy). Each ovary is about the size and shape of an almond.

Questions About D39.8Overview
Is D39.8 (Neoplasm of uncertain behavior of female genital organs) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report neoplasm of uncertain behavior of other specified female genital organs on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D39.8 group to?
When neoplasm of uncertain behavior of other specified female genital organs is the principal diagnosis on an inpatient stay, it groups to MS-DRG 736, 737, 738, 739, 740, 741, 754, 755, 756, with relative weights from 0.9605 to 3.5745 depending on complications. Higher weights mean higher Medicare reimbursement.
What is the ICD-9 equivalent of D39.8?
Under the General Equivalence Mappings, neoplasm of uncertain behavior of other specified female genital organs converts to ICD-9-CM 236.3 (unc behav neo female NEC). The mapping is approximate, so confirm the match fits the documentation.
Footnotes
[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
