- Vulvar intraepithelial neoplasia III VIN III
Type 1 Excludes
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.
A type 1 excludes note is a pure excludes note. It means "NOT CODED HERE!" An Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1 note. An Excludes1 is used when two conditions cannot occur together, such as a congenital form versus an acquired form of the same condition.

AHRQ’s CCSR groups this code into broader clinical categories.
Clinical InformationClinical
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.Bowenoid Papulosis
dysplastic papular lesions presenting on the genitalia of either sex. the lesions are associated with human papillomavirus infection. the majority of cases have a benign clinical course, although, a small number of cases with malignant transformation have been reported.Penile Bowenoid Papulosis
a cutaneous, usually multifocal lesion in the penis characterized by the presence of verrucous papules. it is caused by human papillomavirus infection. morphologically there is bowenoid dysplasia present. progression to invasive carcinoma is infrequent.

Patient EducationClinical
Vulvar Cancer
Vulvar cancer is a rare type of cancer. It forms in a woman's external genitals, called the vulva. The cancer usually grows slowly over several years. First, precancerous cells grow on vulvar skin. This is called vulvar intraepithelial neoplasia (VIN), or dysplasia. Not all VIN cases turn into cancer, but it is best to treat it early.

Questions About D07.1Overview
Is D07.1 (Carcinoma in situ of other and unspecified genital organs) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report carcinoma in situ of vulva on HIPAA-covered claims from October 1, 2025 through September 30, 2026.
What MS-DRG does D07.1 group to?
When carcinoma in situ of vulva 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 D07.1?
Under the General Equivalence Mappings, carcinoma in situ of vulva converts to ICD-9-CM 233.32 (carcinoma in situ vulva). The mapping is a direct match.
