A66.5

What This Code Means

Gangosa is a late-stage manifestation of yaws (a tropical infection caused by bacteria) that causes severe destruction and scarring of the nose and surrounding facial tissues. This condition results from untreated or inadequately treated yaws infection and leads to significant disfigurement.

Coding Tips

• •Gangosa is a late manifestation of yaws, so ensure the underlying yaws diagnosis is also documented and coded appropriately (A66.0-A66.4 for earlier stages)
• •This code is rarely seen in developed countries and is primarily associated with tropical and subtropical regions; verify the patient's geographic history or travel background when coding this diagnosis
