About H36.812

H36.812 is the ICD-10-CM diagnosis code for nonproliferative sickle-cell retinopathy, left eye. 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 H36.81 (nonproliferative sickle-cell retinopathy), H36.812 is specifically for nonproliferative sickle-cell retinopathy, left eye. Related codes cover right eye (H36.811), bilateral (H36.813) and unspecified eye (H36.819).

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 not acceptable as the principal diagnosis for an inpatient stay; it may be reported as a secondary diagnosis.

It was added in FY2024, effective October 1, 2023.
