About E09.65

E09.65 is the ICD-10-CM diagnosis code for drug or chemical induced diabetes mellitus with hyperglycemia. It belongs to category E09 (drug or chemical induced 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 E09.6 (drug or chemical induced diabetes mellitus with other specified complications), E09.65 is specifically for drug or chemical induced diabetes mellitus with hyperglycemia. Related codes cover diabetic arthropathy (E09.61), skin complications (E09.62), oral complications (E09.63), hypoglycemia (E09.64) and other specified complication (E09.69).

Code first: poisoning due to drug or toxin, if applicable (T36-T65 with fifth or sixth character 1-4).

Use an additional code for adverse effect, if applicable, to identify drug (T36-T50 with fifth or sixth character 5). 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 637 (Diabetes with MCC, relative weight 1.4129), DRG 638 (Diabetes with CC, relative weight 0.9019) and DRG 639 (Diabetes without CC/MCC, relative weight 0.6376), in Pre-MDC and MDC 10 (Endocrine, Nutritional and Metabolic Diseases and Disorders), 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 249.80 (secondary diabetes mellitus with other specified manifestations, not stated as uncontrolled, or unspecified).
