Unspecified mycosis (B49)
The ICD-10 code B49 is used for classifying unspecified mycosis, which covers fungal infections when the exact type of fungus is not identified. This code helps document a wide range of fungal infections that affect various parts of the body but lack a more specific diagnosis.
This code includes conditions commonly referred to by terms such as allergic bronchopulmonary mycosis, fungal sinusitis, fungal pneumonia, fungal meningitis, and fungal arthritis. It also covers invasive fungal infections affecting organs like the liver, kidneys, lungs, and central nervous system, as well as rarer manifestations like fungal endophthalmitis (eye infection) and fungal myocarditis. Because it encompasses many synonyms and related conditions; such as fungal spinal epidural abscess, fungal colitis, and fungal granuloma; the ICD-10 code for unspecified mycosis is crucial when diagnosing fungal infections without identified species or exact pathology. This broad classification supports accurate coding when tests have confirmed a fungal infection exists, but further specification is unavailable.
Instructional Notations
Inclusion Terms
These terms are the conditions for which that code is to be used. The terms may be synonyms of the code title, or, in the case of "other specified" codes, the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the Alphabetic Index may also be assigned to a code.

Clinical Terms
The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.
Allergic Fungal Sinusitis
Fungal infection in the PARANASAL SINUSES characterized by common allergy respiratory symptoms, recurrent NASAL POLYPS and/or ASTHMA with buildup of allergic MUCIN.
Chorioamnionitis
INFLAMMATION of the placental membranes (CHORION; AMNION) and connected tissues such as fetal BLOOD VESSELS and UMBILICAL CORD. It is often associated with intrauterine ascending infections during PREGNANCY.
Fungemia
The presence of fungi circulating in the blood. Opportunistic fungal sepsis is seen most often in immunosuppressed patients with severe neutropenia or in postoperative patients with intravenous catheters and usually follows prolonged antibiotic therapy.
