Patient EducationClinical

Abscess

An abscess is a pocket of pus. You can get an abscess almost anywhere in your body. When an area of your body becomes infected, your body's immune system tries to fight the infection. White blood cells go to the infected area, collect within the damaged tissue, and cause inflammation. During this process, pus forms.

Questions About N76.4Overview

What is the ICD-10 code for abscess of vulva?

The ICD-10-CM code for abscess of vulva is N76.4 (sometimes written as N764). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is N76.4 (Other inflammation of vagina and vulva) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report abscess of vulva on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does N76.4 group to?

When abscess of vulva is the principal diagnosis on an inpatient stay, it groups to MS-DRG 742, 759, 743, 758, 757, with relative weights from 0.7687 to 1.8448 depending on complications. Higher weights mean higher Medicare reimbursement.

Is N76.4 a CC or MCC?

CMS lists N76.4 as a CC (complication or comorbidity) for FY 2027. Reported as a secondary diagnosis, it moves the inpatient stay to a higher-weighted DRG within its severity family. It does not count when the principal diagnosis is one of the 61 closely related codes in its exclusion list.

Not as a rule. The Excludes1 note at block N70-N77, which applies to N76.4, lists "abortion or ectopic or molar pregnancy (O00-O07, O08.0)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
