What This Code Means

Type 2 diabetes with damage to the autonomic nerves that control involuntary body functions like heart rate, digestion, and blood pressure. This can cause dizziness, digestive problems, or irregular heartbeat.

Coding Tips

• •Document specific autonomic symptoms such as orthostatic hypotension, gastroparesis, or cardiac dysfunction when present
• •Autonomic neuropathy may coexist with other neuropathy types; code all documented types

Clinical Significance

Type 2 diabetes mellitus with diabetic autonomic neuropathy reflects damage to the nerves controlling involuntary body functions, including cardiovascular regulation, gastrointestinal motility, bladder function, and sudomotor activity. Cardiac autonomic neuropathy is associated with increased mortality risk from silent myocardial ischemia and arrhythmias. Gastroparesis significantly impacts glycemic control by causing unpredictable nutrient absorption.

Documentation Requirements

• ✓Documentation must identify autonomic neuropathy as a complication of Type 2 diabetes, specifying which autonomic systems are affected.
• ✓Cardiac autonomic testing (heart rate variability, orthostatic blood pressure), gastric emptying studies, urodynamic testing, or sudomotor function tests should be documented as applicable.
• ✓Symptoms such as orthostatic hypotension, gastroparesis, or neurogenic bladder should be described.
