Oth diabetes w diabetic peripheral angiopathy w gangrene

This code signifies a form of diabetes mellitus, not type 1 or type 2, that has led to peripheral artery disease (angiopathy) in the extremities, which has progressed to tissue death (gangrene). This indicates severe vascular compromise in a patient with a less common or unspecified type of diabetes.

Apply this code when documentation clearly states "other specified diabetes mellitus" and explicitly links it to peripheral angiopathy with gangrene. This typically applies to patients with secondary diabetes, genetic defects in beta-cell function, or other specified types of diabetes experiencing this severe complication.

• Always confirm the specific type of diabetes; "other specified" is distinct from type 1 or type 2.
• Ensure documentation explicitly states both "peripheral angiopathy" and "gangrene" as complications.
• Sequence this code as the primary diagnosis if it is the reason for the encounter, or as a secondary diagnosis if it's a co-morbidity impacting care.
