Is H90 a billable ICD-10-CM code?

No. H90 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does H90 sit in the tabular list?

Diseases of the ear and mastoid process (H60-H95), in the block Other disorders of ear (H90-H94).

What cannot be coded together with H90?

H90 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

H90 — Conductive and sensorineural hearing loss

Non-billable headerICD-10-CM

H90 is a non-billable header ICD-10-CM code for conductive and sensorineural hearing loss. 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.

deaf nonspeaking NEC (H91.3)
deafness NOS (H91.9-)
hearing loss NOS (H91.9-)
noise-induced hearing loss (H83.3-)
ototoxic hearing loss (H91.0-)
sudden (idiopathic) hearing loss (H91.2-)

Other codes that can never be billed with H90

These codes carry an Excludes1 note pointing at H90. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H90 alone.

Q16Congenital malformations of ear causing impairment of hearing
H91Other and unspecified hearing loss

Risk adjustment

H90 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 H90

10 child codes. Green means billable.
