- Conductive deafness NOS
Excludes1
Not coded here: the excluded code is never reported together with this one, unless the two conditions are unrelated.
Excludes2
Not included here: the excluded condition is not part of this code, but a patient may have both, so both codes may be reported.

Hearing Disorders and Deafness
It's frustrating to be unable to hear well enough to enjoy talking with friends or family. Hearing disorders make it hard, but not impossible, to hear. They can often be helped. Deafness can keep you from hearing sound at all.

Questions About H90.2Overview
What is the ICD-10 code for conductive hearing loss, unspecified?
The ICD-10-CM code for conductive hearing loss, unspecified is H90.2 (sometimes written as H902). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is H90.2 (Conductive and sensorineural hearing loss) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report conductive hearing loss, unspecified on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does H90.2 group to?
When conductive hearing loss, unspecified is the principal diagnosis on an inpatient stay, it groups to MS-DRG 156, 155, 154, with relative weights from 0.6656 to 1.5916 depending on complications. Higher weights mean higher Medicare reimbursement.
Can H90.2 be reported with H91.3?
Not as a rule. The Excludes1 note at H90, which applies to H90.2, lists "deaf nonspeaking NEC (H91.3)". 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).
What is the ICD-9 equivalent of H90.2?
Under the General Equivalence Mappings, conductive hearing loss, unspecified converts to ICD-9-CM 389.00 (conduct hearing loss NOS). The mapping is approximate, so confirm the match fits the documentation.
