Mucormycosis, unspecified

This code represents a severe fungal infection caused by molds belonging to the order Mucorales, affecting various body sites such as the sinuses, brain, lungs, or skin. It is an opportunistic infection primarily seen in immunocompromised individuals.

Assign this code when the patient's medical record documents a diagnosis of mucormycosis without further specification of the affected anatomical site. This code is appropriate when the physician's documentation clearly states "mucormycosis" but does not provide details to allow for a more specific site-driven code (e.g., pulmonary mucormycosis).

• Avoid using this code if the documentation specifies the site of mucormycosis (e.g., rhinocerebral, pulmonary, cutaneous); instead, use the more specific B46.0-B46.4 or B46.8.
• Always review the entire medical record for any mention of the affected body system or organ to ensure the most specific code is chosen.
• Consider an additional code to identify the underlying immunocompromised state, if applicable (e.g., diabetes mellitus, malignancy, HIV).
