H36.89Other retinal disorders in diseases classified elsewhere

H36.89 is the ICD-10-CM diagnosis code for other retinal disorders in diseases classified elsewhere. It belongs to category H36 (retinal disorders in diseases classified elsewhere), block H30-H36 (disorders of choroid and retina) and chapter 7 (diseases of the eye and adnexa). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within H36.8, choose H36.89 (Other retinal disorders in diseases classified elsewhere) only when documentation doesn't support a more specific option: nonproliferative sickle-cell retinopathy (H36.81) and proliferative sickle-cell retinopathy (H36.82).

Code first underlying disease, such as: lipid storage disorders (E75.-) and sickle-cell disorders (D57.-).

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 124 (Other Disorders of the Eye with MCC or Thrombolytic Agent, relative weight 1.2471) and DRG 125 (Other Disorders of the Eye without MCC, relative weight 0.7702), in MDC 02 (Diseases and Disorders of the Eye), 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 was added in FY2024, effective October 1, 2023.
