B47.1

What This Code Means

Actinomycetoma is a chronic bacterial infection of the skin and underlying tissues, usually affecting the foot or hand, that causes swelling, draining sinuses, and the discharge of granules containing bacteria. It is a slowly progressive infection that requires prolonged antibiotic treatment.

Coding Tips

• •Verify the specific site of infection (foot, hand, or other body part) as this may require an additional anatomical location code for complete specificity
• •Confirm the diagnosis is actinomycetoma (bacterial) rather than eumycetoma (fungal), as they are coded differently and require different treatment approaches
