Is H90.4 a billable ICD-10-CM code?

No. H90.4 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does H90.4 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 H90.4?

H90.4 carries Excludes1 notes, which means the conditions they list can never be coded together with it on the same encounter. Some are written on the categories above H90.4 (H90) and apply to it just the same.

H90.4

H90.4 — Sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side

Non-billable headerICD-10-CM

H90.4 is a non-billable header ICD-10-CM code for sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 inherited from the categories above H90.4

These are not written on H90.4, but they bind it: a note on a category applies to every code beneath it. Billing H90.4 with anything listed here is a denial.

Written on H90 — Conductive and sensorineural hearing loss

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 H90.4

These codes carry an Excludes1 note pointing at H90.4. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading H90.4 alone.

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

Risk adjustment

H90.4 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 history

H90.4 has not changed since FY2024 — no addition, revision or deletion across the three most recent ICD-10-CM releases.

Code to one of these instead H90.4
