Questions About N76.82Overview

What is the ICD-10 code for fournier disease of vagina and vulva?

The ICD-10-CM code for fournier disease of vagina and vulva is N76.82 (sometimes written as N7682). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is N76.82 (Other specified inflammation of vagina and vulva) a billable code?

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

What MS-DRG does N76.82 group to?

When fournier disease 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.

Can N76.82 be reported with O08.0?

Not as a rule. The Excludes1 note at block N70-N77, which applies to N76.82, 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).

Does N76.82 need an additional code?

When the condition applies, yes. The Use Additional Code note at N76, which applies to N76.82, reads: code (B95-B97), to identify infectious agent. The additional code is reported after N76.82.

What HCC is N76.82?

N76.82 (fournier disease of vagina and vulva) maps to CMS-HCC Category 92 (Bone/Joint/Muscle/Severe Soft Tissue Infections/Necrosis), commonly written as HCC 92, in the CMS-HCC V28 model used for Medicare Advantage risk adjustment in payment year 2027. It mapped to HCC 39 under the retired V24 model. It also maps in the PACE (CMS-HCC V22), ESRD (V21), and ESRD (V24) models. It does not map to any RxHCC in the Part D prescription drug model.

Does N76.82 risk-adjust for Medicare Advantage payment?

Yes. When documented and reported on a Medicare Advantage encounter, N76.82 adds a risk adjustment factor of about 0.479 to the beneficiary's RAF score for a community, non-dual, aged enrollee (published V28 weights range from 0.471 to 0.632 depending on the payment segment). HCC 92 sits at the top of its hierarchy, so no other condition category supersedes it. See the full factor table on the HCC 92 category page.
