Q80

Q80 — Congenital ichthyosis

Non-billable headerICD-10-CM

Q80 is a non-billable header ICD-10-CM code for congenital ichthyosis. 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.

Refsum's disease (G60.1)

Other codes that can never be billed with Q80

These codes carry an Excludes1 note pointing at Q80. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q80 alone.

L85.0Acquired ichthyosis
P83Other conditions of integument specific to newborn

Risk adjustment

Q80 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 Q80

7 child codes. Green means billable.
