Other and unspecified mycoses

This code represents a fungal infection that is not specifically categorized elsewhere or for which the exact type of fungus is unknown. It indicates a systemic or localized mycosis where more precise identification is lacking.

Use this code when documentation confirms a fungal infection but does not specify the causative organism (e.g., "mycosis, unspecified") or when the identified fungus falls outside of the more specific ICD-9-CM categories for mycoses. This code is appropriate when the physician's diagnosis is broad or when laboratory results are pending or inconclusive regarding the specific fungal species.

• Avoid using this code if a more specific mycosis code is available and supported by documentation.
• Query the provider for more specific fungal identification if possible, especially if treatment depends on the specific pathogen.
• Consider sequencing this code after any associated symptoms or manifestations of the fungal infection.
