About E11.36

E11.36 is the ICD-10-CM diagnosis code for type 2 diabetes mellitus with diabetic cataract. It belongs to category E11 (type 2 diabetes mellitus), block E08-E13 (diabetes mellitus) and chapter 4 (endocrine, nutritional and metabolic diseases). It is billable, so it can be reported on its own for dates of service from October 1, 2026 through September 30, 2027.

Within E11.3 (type 2 diabetes mellitus with ophthalmic complications), E11.36 is specifically for type 2 diabetes mellitus with diabetic cataract. Related codes cover unspecified diabetic retinopathy (E11.31), mild nonproliferative diabetic retinopathy (E11.32), moderate nonproliferative diabetic retinopathy (E11.33), severe nonproliferative diabetic retinopathy (E11.34), proliferative diabetic retinopathy (E11.35), diabetic macular edema, resolved following treatment (E11.37) and other diabetic ophthalmic complication (E11.39).

Use an additional code to identify control using: injectable non-insulin antidiabetic drugs (Z79.85), insulin (Z79.4), oral antidiabetic drugs (Z79.84) and oral hypoglycemic drugs (Z79.84).

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 008 (Simultaneous Pancreas, Islet Cell and Kidney Transplant, relative weight 5.5146), DRG 010 (Pancreas or Islet Cell Transplant, relative weight 7.5259), DRG 019 (Simultaneous Pancreas, Islet Cell and Kidney Transplant with Hemodialysis, relative weight 7.5493), 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 Pre-MDC and 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 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 250.50 (diabetes with ophthalmic manifestations, type II or unspecified type, not stated as uncontrolled) and 366.41 (diabetic cataract).
