Not Valid for Submission

ICD-10 B46 is a "header" nonspecific and non-billable code code, consider using a code with a higher level of specificity for a diagnosis of zygomycosis. The code is NOT valid for the year 2019 for the submission of HIPAA-covered transactions.

Consider the following ICD-10 codes with a higher level of specificity:

  • B46.0 - Pulmonary mucormycosis
  • B46.1 - Rhinocerebral mucormycosis
  • B46.2 - Gastrointestinal mucormycosis
  • B46.3 - Cutaneous mucormycosis
  • B46.4 - Disseminated mucormycosis
  • B46.5 - Mucormycosis, unspecified
  • B46.8 - Other zygomycoses
  • B46.9 - Zygomycosis, unspecified

Information for Medical Professionals

Clinical Information

Notes:

  • Zygomycosis: Infection in humans and animals caused by fungi in the class Zygomycetes. It includes MUCORMYCOSIS and entomophthoramycosis. The latter is a tropical infection of subcutaneous tissue or paranasal sinuses caused by fungi in the order Entomophthorales. Phycomycosis, closely related to zygomycosis, describes infection with members of Phycomycetes, an obsolete classification.

Terms:

  • Entomophthoramycosis; Phycomycosis

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.

ICD-10 Footnotes

General Equivalence Map Definitions
The ICD-10 and ICD-9 GEMs are used to facilitate linking between the diagnosis codes in ICD-9-CM and the new ICD-10-CM code set. The GEMs are the raw material from which providers, health information vendors and payers can derive specific applied mappings to meet their needs.

  • Approximate Flag - The approximate flag is on, indicating that the relationship between the code in the source system and the code in the target system is an approximate equivalent.
  • No Map Flag - The no map flag indicates that a code in the source system is not linked to any code in the target system.
  • Combination Flag - The combination flag indicates that more than one code in the target system is required to satisfy the full equivalent meaning of a code in the source system.
