What This Code Means

Type 2 diabetes with other blood vessel or circulation problems not specified elsewhere, such as diabetic retinopathy affecting blood vessels or other vascular complications.

Coding Tips

• •Use this code only when circulatory complications do not fit E11.51 or E11.52; document the specific complication
• •Ensure the circulatory problem is directly attributable to diabetes

Clinical Significance

Type 2 diabetes mellitus with other circulatory complications captures vascular conditions attributable to diabetes beyond peripheral angiopathy, including diabetic microangiopathy affecting various organs, thrombotic complications, or other systemic vascular manifestations. These conditions reflect the pervasive vascular damage caused by chronic hyperglycemia and may contribute to multi-organ dysfunction requiring complex medical management.

Documentation Requirements

• ✓The provider must document the specific circulatory complication and its causal relationship to Type 2 diabetes.
• ✓Relevant vascular studies, laboratory findings, and clinical examination results should be included.
• ✓The documentation must confirm the condition is not peripheral angiopathy (E11.51/E11.52) to justify this residual code.
• ✓Treatment plans addressing the vascular complication should be noted.
