2021 ICD-10-CM Code B40.9
Blastomycosis, unspecified
Valid for Submission
B40.9 is a billable diagnosis code used to specify a medical diagnosis of blastomycosis, unspecified. The code B40.9 is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
The ICD-10-CM code B40.9 might also be used to specify conditions or terms like blastomyces dermatitidis or blastomyces gilchristii, blastomycosis, blastomycotic prostatitis, infection by blastomyces dermatitidis, non-bacterial prostatitis , urogenital blastomycosis, etc.
Unspecified diagnosis codes like B40.9 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Clinical Information
- BLASTOMYCOSIS-. a fungal infection that may appear in two forms: 1 a primary lesion characterized by the formation of a small cutaneous nodule and small nodules along the lymphatics that may heal within several months; and 2 chronic granulomatous lesions characterized by thick crusts warty growths and unusual vascularity and infection in the middle or upper lobes of the lung.
- PARACOCCIDIOIDOMYCOSIS-. a mycosis affecting the skin mucous membranes lymph nodes and internal organs. it is caused by paracoccidioides brasiliensis. it is also called paracoccidioidal granuloma. superficial resemblance of p. brasiliensis to blastomyces brasiliensis blastomyces may cause misdiagnosis.
- LOBOMYCOSIS-. a chronic fungal subcutaneous infection endemic in rural regions in south america and central america. the causal organism is lacazia labol.

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code B40.9 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.

Information for Patients
Fungal Infections
Also called: Mycoses
If you have ever had athlete's foot or a yeast infection, you can blame a fungus. A fungus is a primitive organism. Mushrooms, mold and mildew are examples. Fungi live in air, in soil, on plants and in water. Some live in the human body. Only about half of all types of fungi are harmful.
Some fungi reproduce through tiny spores in the air. You can inhale the spores or they can land on you. As a result, fungal infections often start in the lungs or on the skin. You are more likely to get a fungal infection if you have a weakened immune system or take antibiotics.
Fungi can be difficult to kill. For skin and nail infections, you can apply medicine directly to the infected area. Oral antifungal medicines are also available for serious infections.
