ICD-10 Code B46.4 | Disseminated mucormycosis Symptoms, Diagnosis, Billing

Disseminated mucormycosis is a severe fungal infection caused by mucormycetes, primarily affecting immunocompromised individuals. It can lead to widespread tissue necrosis and systemic complications. Accurate coding with ICD-10 Code B46.4 is essential for proper diagnosis, documentation, billing, and public health reporting, ensuring that healthcare providers can effectively manage and treat this life-threatening condition.

What is ICD-10 Code B46.4 for Disseminated mucormycosis?

ICD-10 Code B46.4 represents disseminated mucormycosis, a serious fungal infection characterized by the invasion of mucormycetes into multiple organ systems. This code should be used when documenting cases of disseminated mucormycosis, particularly in patients with underlying conditions such as diabetes or immunosuppression, to ensure accurate billing and clinical management.

ICD-10 Code B46.4 – Clinical Definition and Explanation of Disseminated mucormycosis

Disseminated mucormycosis is caused by the inhalation or inoculation of mucormycetes, leading to rapid progression of infection, particularly in immunocompromised patients. This condition necessitates immediate medical intervention due to its high mortality rate.

Key Clinical Features:

• Rapid onset of symptoms, including fever and respiratory distress.
• Necrotic lesions in affected tissues, often visible on imaging studies.
• Commonly associated with diabetes mellitus and neutropenia.
• Potential for multi-organ failure if not treated promptly.

ICD-10 Code B46.4 for Disseminated mucormycosis – SOAP Notes & Clinical Use

ICD-10 Code B46.4 is utilized in SOAP notes to document the clinical presentation, assessment, and treatment of disseminated mucormycosis. It plays a crucial role in both acute and chronic care settings, ensuring comprehensive patient management.

What Does ICD-10 Code B46.4 for Disseminated mucormycosis Mean in SOAP Notes?

In SOAP notes, ICD-10 Code B46.4 connects subjective patient reports and objective clinical findings to a formal diagnosis of disseminated mucormycosis. This ensures continuity of care, supports accurate billing, and meets EHR documentation standards.

Treatment Options for ICD-10 Code B46.4 – Disseminated mucormycosis

Disseminated mucormycosis requires urgent medical attention and often hospitalization for effective management.

• First-line: Amphotericin B (liposomal formulation) for 4-6 weeks.
• Alternative: Posaconazole or Isavuconazole for patients intolerant to amphotericin.
• Consider adjunctive surgical debridement for necrotic tissue.

Supportive Care:

• Monitor vital signs and laboratory parameters closely.
• Manage underlying conditions, such as diabetes or immunosuppression.
• Provide nutritional support and fluid management.

Infection Control:

• Implement strict isolation precautions for immunocompromised patients.
• Educate staff on fungal infection prevention measures.
• Limit exposure to potential sources of mucormycetes in healthcare settings.
