Is N76.81 (Other specified inflammation of vagina and vulva) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report mucositis (ulcerative) of vagina and vulva on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does N76.81 group to?
When mucositis (ulcerative) of vagina and 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 N76.81 a CC or MCC?
CMS lists N76.81 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 6 closely related codes in its exclusion list.

Not as a rule. The Excludes1 note at block N70-N77, which applies to N76.81, 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).
