§ 4.97 Schedule of ratings—respiratory system.

Mucormycosis

A fungal infection that may affect the lungs and cause breathing difficulty and fever.

What the rating means

Mucormycosis (diagnostic code 6839) is rated under the General Rating Formula for Mycotic Lung Disease, which also covers diagnostic codes 6834 through 6838. VA rates this condition based on the severity of your ongoing symptoms and whether the infection is still active.

A 100% rating applies when you have chronic pulmonary mucormycosis with persistent fever, weight loss, night sweats, or massive hemoptysis. A 50% rating applies when the condition is chronic and requires suppressive therapy, but symptoms are no more than minimal, such as occasional minor hemoptysis or productive cough. A 30% rating applies when the condition is chronic with those same minimal symptoms but without the need for suppressive therapy. A 0% rating applies when the mycotic lesions have healed, are inactive, and you have no symptoms.

The key separating factors are whether the disease is still active, whether it requires ongoing suppressive therapy, and how severe your symptoms are.

Evidence that helps

To support a higher rating, your medical records should document the specific symptoms VA looks for at each level. For a 100% rating, records showing persistent fever, documented weight loss, recurring night sweats, or massive hemoptysis are central. Hospitalization records, lab results, and physician notes that track these symptoms over time are particularly relevant.

For a 50% rating, records should show that you are on suppressive therapy — meaning ongoing antifungal treatment — and that your symptoms remain minimal, such as occasional minor hemoptysis or a productive cough. Pharmacy records and treatment plans can help establish this.

For a 30% rating, similar symptom records apply, but without documentation of suppressive therapy. For a 0% rating, imaging studies or lab findings showing healed and inactive lesions, combined with a physician's statement confirming you are asymptomatic, reflect that level. Statements from you or people who know you describing how symptoms affect your daily life and work can also support the overall picture your medical records present.
