A31: Infection due to other mycobacteria

A31.8: Other mycobacterial infections

Other mycobacterial infections, as coded by A31.8, refer to diseases caused by certain strains of mycobacteria, which are a type of bacterium. These strains are not associated with tuberculosis or leprosy, but can still lead to serious health problems. The bacteria are found in many environments around the world, including water and soil, and an infection can occur when an individual inhales or ingests them, or they enter through a break in the skin. Symptoms can vary widely and may include persistent fevers, weight loss, fatigue, or localized pain, depending on the system of the body that is affected. These infections can progress over a period of weeks to months and primarily affect the lungs, skin, or can disseminate to multiple organs if not timely diagnosed and treated.
