B35-B49: Mycoses

B48: Other mycoses, not elsewhere classified

ICD-10 code B48 falls under a group of conditions referred to as "Other mycoses, not elsewhere classified." This group comprises various types of fungal infections that specifically do not fall into other classes of fungal diseases. Fungi, which can be found in soil, air, and water, can cause these infections when they enter through a break in the skin or are inhaled into the lungs. Symptoms vary widely due to the types and location of the fungal infection, but can include skin changes, cough, fever, and fatigue. These infections can be superficial, affecting just the skin and its structures, or systemic, affecting multiple systems in the body and potentially causing severe illnesses. Disease progression varies based on the type of fungus, the person's immune response, and whether it's a local or systemic infection. If left untreated, systemic mycoses, in particular, can be life-threatening.
