Code Description

ICD-10 E09.35 is a billable code used to indicate a diagnosis of drug or chemical induced diabetes mellitus with proliferative diabetic retinopathy.

Key Diagnostic Point:

E09.35 refers to diabetes mellitus that is induced by drugs or chemicals, specifically characterized by the presence of proliferative diabetic retinopathy. This condition arises when certain medications or chemical exposures lead to insulin resistance or impaired insulin secretion, resulting in elevated blood glucose levels. Proliferative diabetic retinopathy is a severe complication of diabetes, marked by the growth of new blood vessels in the retina, which can lead to vision loss if not managed appropriately. Patients may present with symptoms such as blurred vision, floaters, or sudden vision changes. Management of this condition often requires a multidisciplinary approach, including endocrinology for diabetes management and ophthalmology for retinal care. Regular monitoring of HbA1c levels is crucial, as it reflects long-term glucose control and helps guide treatment decisions. Insulin therapy may be necessary for glycemic control, especially in cases where oral hypoglycemics are ineffective due to the drug-induced nature of the diabetes.

Complexity Factors

  • Differentiating between drug-induced diabetes and other types of diabetes
  • Identifying the specific drug or chemical responsible for the condition
  • Documenting the presence and severity of proliferative diabetic retinopathy
  • Understanding the interplay between diabetes management and retinopathy treatment

Audit Risk Factors

  • Inadequate documentation of the drug or chemical causing diabetes
  • Failure to document the severity of diabetic retinopathy
  • Incorrect coding of diabetes type or complications
  • Lack of regular monitoring of HbA1c levels

Frequently Asked Questions

What types of drugs can induce diabetes mellitus?

Several classes of medications can induce diabetes, including corticosteroids, certain antipsychotics, and some chemotherapy agents. It is important to review the patient's medication history to identify potential causes.

How is proliferative diabetic retinopathy diagnosed?

Proliferative diabetic retinopathy is diagnosed through a comprehensive eye exam, which may include retinal photography and fluorescein angiography to assess the extent of neovascularization.
