Is N85 a billable ICD-10-CM code?

No. N85 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does N85 sit in the tabular list?

Diseases of the genitourinary system (N00-N99), in the block Noninflammatory disorders of female genital tract (N80-N98).

What cannot be coded together with N85?

N85 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

N85 — Other noninflammatory disorders of uterus, except cervix

Non-billable headerICD-10-CM

N85 is a non-billable header ICD-10-CM code for other noninflammatory disorders of uterus, except cervix. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

endometriosis (N80.-)
inflammatory diseases of uterus (N71.-)
noninflammatory disorders of cervix, except malposition (N86-N88)
polyp of corpus uteri (N84.0)
uterine prolapse (N81.-)

Other codes that can never be billed with N85

These codes carry an Excludes1 note pointing at N85. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading N85 alone.

N71Inflammatory disease of uterus, except cervix
N83.6Hematosalpinx
N84.0Polyp of corpus uteri

Risk adjustment

N85 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead N85

10 child codes. Green means billable.
