About H94.83
H94.83 is the ICD-10-CM diagnosis code for other specified disorders of ear in diseases classified elsewhere, bilateral. It belongs to category H94 (other disorders of ear in diseases classified elsewhere), block H90-H94 (other disorders of ear) and chapter 8 (diseases of the ear and mastoid process). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.
Within H94.8 (other specified disorders of ear in diseases classified elsewhere), H94.83 is specifically for other specified disorders of ear in diseases classified elsewhere, bilateral. Related codes cover unspecified ear (H94.80), right ear in diseases classified elsewhere (H94.81) and left ear in diseases classified elsewhere (H94.82).
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.
It is a manifestation code, so it describes the effect of an underlying disease and can't be the principal diagnosis. Code the underlying condition first.
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
Before ICD-10, this condition was coded in ICD-9-CM as 388.8 (other disorders of ear).
