Zygomycosis, unspecified

This code represents an unspecific fungal infection caused by organisms in the subphylum Mucoromycotina, formerly known as Zygomycetes. These infections, often severe and rapidly progressive, typically affect immunocompromised individuals.

Assign this code when documentation indicates a diagnosis of zygomycosis but the specific type or causative organism is not further specified. This is appropriate when the provider has confirmed a zygomycotic infection but lacks the detailed information to code to a more specific site or organism.

• Avoid using this code if a more specific anatomical site of infection (e.g., pulmonary, rhinocerebral) or causative organism (e.g., Mucor, Rhizopus) is documented.
• Always review the medical record for additional details that would allow for more precise coding, such as specific organ involvement or the identified fungal species.
• Consider sequencing this code after codes for underlying conditions that predispose patients to fungal infections, such as diabetes mellitus or immunosuppression.
