Zygomycosis [Phycomycosis or Mucormycosis]

This code identifies a severe fungal infection caused by molds belonging to the order Mucorales, commonly known as mucormycosis, or less commonly, phycomycosis. These infections are typically opportunistic and can affect various body sites, including the sinuses, brain, lungs, and skin, often leading to rapid tissue necrosis.

Use this code for documented cases of zygomycosis, mucormycosis, or phycomycosis confirmed by laboratory identification of the causative fungi. This code is appropriate when the patient presents with symptoms and diagnostic findings consistent with this aggressive fungal infection, particularly in immunocompromised individuals.

• Ensure physician documentation clearly specifies "zygomycosis," "mucormycosis," or "phycomycosis" to support this code.
• Do not confuse with other systemic mycoses; this code is specific to infections caused by Mucorales.
• Code any associated manifestations or complications (e.g., pneumonia, cerebral abscess) separately, following sequencing guidelines.
