ICD-10 code for conductive deafness

The ICD-10-CM code for conductive deafness is H90.2 (Conductive hearing loss, unspecified). The official index lists 5 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H90.2.

Within H90, choose H90.2 (Conductive hearing loss, unspecified) only when documentation doesn't support a more specific option: conductive hearing loss, bilateral (H90.0), conductive hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.1), sensorineural hearing loss, bilateral (H90.3), sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.4), unspecified sensorineural hearing loss (H90.5), mixed conductive and sensorineural hearing loss, bilateral (H90.6), mixed conductive and sensorineural hearing loss, unilateral with unrestricted hearing on the contralateral side (H90.7), mixed conductive and sensorineural hearing loss, unspecified (H90.8) and 1 more.

It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.

In MS-DRG v44.0, it is part of the grouping logic for DRG 154 (Other Ear, Nose, Mouth and Throat Diagnoses with MCC, relative weight 1.5921), DRG 155 (Other Ear, Nose, Mouth and Throat Diagnoses with CC, relative weight 0.9322) and DRG 156 (Other Ear, Nose, Mouth and Throat Diagnoses without CC/MCC, relative weight 0.6659), in MDC 03 (Diseases and Disorders of the Ear, Nose, Mouth and Throat), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
