Cutaneous mycobacterial infection

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

A skin infection caused by mycobacteria (bacteria related to tuberculosis) that affects the outer layers of the skin. This type of infection typically develops after exposure to contaminated water or soil and causes localized skin lesions or nodules.

Coding Tips

  • •Verify the specific site of the cutaneous infection (arm, leg, trunk, etc.) as additional characters may be required for anatomical specificity in some coding scenarios
  • •Distinguish between cutaneous mycobacterial infections (A31.1) and other mycobacterial conditions like tuberculosis (A15-A19) or leprosy (A30) to ensure accurate code selection
