About E13.39

E13.39 is the ICD-10-CM diagnosis code for other specified diabetes mellitus with other diabetic ophthalmic complication. It belongs to category E13 (other specified 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 E13.3, choose E13.39 (other diabetic ophthalmic complication) only when documentation doesn't support a more specific option: unspecified diabetic retinopathy (E13.31), mild nonproliferative diabetic retinopathy (E13.32), moderate nonproliferative diabetic retinopathy (E13.33), severe nonproliferative diabetic retinopathy (E13.34), proliferative diabetic retinopathy (E13.35), diabetic cataract (E13.36) and diabetic macular edema, resolved following treatment (E13.37).

Use an additional code to identify manifestation, such as: diabetic glaucoma (H40-H42). 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 249.50 (secondary diabetes mellitus with ophthalmic manifestations, not stated as uncontrolled, or unspecified) and 250.50 (diabetes with ophthalmic manifestations, type II or unspecified type, not stated as uncontrolled).
