Type 2 diabetes w diabetic peripheral angiopathy w gangrene

This code signifies a patient diagnosed with Type 2 diabetes who has developed peripheral angiopathy, a condition affecting blood vessels in the extremities, and has progressed to gangrene. This indicates severe vascular compromise and tissue necrosis directly attributable to their diabetic condition.

Apply this code when documentation clearly states Type 2 diabetes and specifies the presence of diabetic peripheral angiopathy with associated gangrene. This often occurs in patients with long-standing or poorly controlled diabetes presenting with non-healing ulcers, black discoloration of digits or limbs, and clinical signs of tissue death. Supporting documentation includes physician notes detailing the diabetic status, vascular assessment findings (e.g., absent pulses, Doppler studies), and a definitive diagnosis of gangrene.

• Ensure the documentation explicitly links the peripheral angiopathy and gangrene to the patient's Type 2 diabetes.
• Do not use this code if the gangrene is due to a non-diabetic cause, such as trauma or acute arterial occlusion without underlying diabetic angiopathy.
• Sequence this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it is a co-morbidity impacting treatment.
