ICD-10 code for Deafmutism NEC

The ICD-10-CM code for Deafmutism NEC is H91.3 (Deaf nonspeaking, not elsewhere classified). The official index lists 2 more specific codes, so check the documentation for details such as type, cause, site or severity before settling on H91.3.

Within H91 (other and unspecified hearing loss), H91.3 is specifically for Deaf nonspeaking, not elsewhere classified. Related codes cover Ototoxic hearing loss (H91.0), Presbycusis (H91.1), sudden idiopathic hearing loss (H91.2), other specified hearing loss (H91.8) and unspecified hearing loss (H91.9).

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.
