About H93.092

H93.092 is the ICD-10-CM diagnosis code for unspecified degenerative and vascular disorders of left ear. It belongs to category H93 (other disorders of ear, not elsewhere classified), 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 H93.09 (unspecified degenerative and vascular disorders of ear), H93.092 is specifically for unspecified degenerative and vascular disorders of left ear. Related codes cover right ear (H93.091), bilateral (H93.093) and unspecified ear (H93.099).

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 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 388.00 (degenerative and vascular disorders, unspecified).
