M89.449

What This Code Means

A condition where bones and tissues in the hand thicken and enlarge abnormally, often causing swelling and clubbing of the fingers.

Coding Tips

• •Verify the underlying cause (lung disease, heart disease, or malignancy) as hypertrophic osteoarthropathy is often secondary to another condition
• •Use this code only when the specific hand (right or left) cannot be determined; otherwise use M89.441 or M89.442
