A30.5

What This Code Means

Lepromatous leprosy is the most severe form of Hansen's disease, a chronic bacterial infection caused by Mycobacterium leprae that primarily affects the skin and nerves. This type involves widespread skin lesions and high bacterial loads throughout the body.

Coding Tips

• •Verify documentation specifies 'lepromatous' type rather than other forms (tuberculoid, borderline, or indeterminate) as each has a distinct ICD-10-CM code
• •This code may require additional codes to document affected body sites or complications such as nerve damage, eye involvement, or secondary infections
