Instructional NotesGuidance
Instructions from the official ICD-10-CM Tabular List that apply to H91.90: its own notes plus those printed at H91 and Chapter 8. A note printed at a category, block or chapter applies to every code under it.
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.
- certain conditions originating in the perinatal period (P04-P96)
- certain infectious and parasitic diseases (A00-B99)
- complications of pregnancy, childbirth and the puerperium (O00-O9A)
- congenital malformations, deformations and chromosomal abnormalities (Q00-Q99)
- endocrine, nutritional and metabolic diseases (E00-E88)
- injury, poisoning and certain other consequences of external causes (S00-T88)
- neoplasms (C00-D49)
- symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)

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 H91.90Overview
What is the ICD-10 code for unspecified hearing loss, unspecified ear?
The ICD-10-CM code for unspecified hearing loss, unspecified ear is H91.90 (sometimes written as H9190). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
Is H91.90 (Unspecified hearing loss) a billable code?
Yes. This is a billable ICD-10-CM code, specific enough to report unspecified hearing loss, unspecified ear on HIPAA-covered claims from October 1, 2026 through September 30, 2027.
What MS-DRG does H91.90 group to?
When unspecified hearing loss, unspecified ear 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 H91.90 be reported with a code from H93.2?
Not as a rule. The Excludes1 note at H91, which applies to H91.90, lists "abnormal auditory perception (H93.2-)". 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 H91.90?
Under the General Equivalence Mappings, unspecified hearing loss, unspecified ear converts to ICD-9-CM 389.9 (hearing loss NOS). The mapping is approximate, so confirm the match fits the documentation.
