What each rating requires
The VA assigns the highest level your evidence actually supports. Read up the stack until your records stop matching.
- 100%
Chronic pulmonary mycosis with persistent fever, weight loss, night sweats, or massive hemoptysis
- 50%
Chronic pulmonary mycosis requiring suppressive therapy with no more than minimal symptoms such as occasional minor hemoptysis or productive cough
- 30%
Chronic pulmonary mycosis with minimal symptoms such as occasional minor hemoptysis or productive cough
- 0%
Healed and inactive mycotic lesions, asymptomatic

Notes on this code
These notes are part of the regulation. They change how the levels above are applied.
- Note: Coccidioidomycosis has an incubation period up to 21 days, and the disseminated phase is ordinarily manifest within six months of the primary phase. However, there are instances of dissemination delayed up to many years after the initial infection which may have been unrecognized. Accordingly, when service connection is under consideration in the absence of record or other evidence of the disease in service, service in southwestern United States where the disease is endemic and absence of prolonged residence in this locality before or after service will be the deciding factor.
Histoplasmosis of Lung (VA Diagnostic Code 6834)
Understanding how the VA rates chronic fungal lung disease under the respiratory system schedule.
What This Condition Is
Histoplasmosis of the lung is a mycotic (fungal) lung disease. Under the VA rating schedule, it is evaluated in the Respiratory System category (§ 4.97, Diagnostic Code 6834) using the General Rating Formula for Mycotic Lung Disease.
The way the VA assigns a disability rating depends on how active the disease is, the severity of symptoms, and whether ongoing treatment is needed.
Available Rating Levels
The following rating levels are used for this condition:
| Rating | What It Reflects |
|---|---|
| 100% | Chronic pulmonary mycosis with persistent fever, weight loss, night sweats, or massive hemoptysis (coughing up blood). |
| 50% | Chronic pulmonary mycosis requiring suppressive therapy with no more than minimal symptoms, such as occasional minor hemoptysis or productive cough. |
| 30% | Chronic pulmonary mycosis with minimal symptoms, such as occasional minor hemoptysis or productive cough. |
| 0% | Healed and inactive mycotic lesions that are asymptomatic. |
What the VA Looks For
When rating this condition, the VA considers:
- Symptom severity — including persistent fever, weight loss, night sweats, or hemoptysis (coughing up blood) at the highest level, versus only minimal symptoms like occasional minor hemoptysis or productive cough at lower levels.
- Whether the disease is chronic and active versus healed, inactive, and asymptomatic.
- Whether suppressive therapy is required to manage the condition, which distinguishes the 50% level from the 30% level.
Note on Related Fungal Conditions and Service Connection
The rating schedule includes an important note on how these fungal lung diseases relate to service:
Coccidioidomycosis has an incubation period up to 21 days, and the disseminated phase is ordinarily manifest within six months of the primary phase. However, there are instances of dissemination delayed up to many years after the initial infection which may have been unrecognized. Accordingly, when service connection is under consideration in the absence of record or other evidence of the disease in service, service in southwestern United States where the disease is endemic and absence of prolonged residence in this locality before or after service will be the deciding factor.

Read each rung against what your medical records already say. The level your records document today is the one the VA can support today.
Name the gap
Look at the rung above yours and write down exactly what it asks for that your file does not show yet — a diagnosis, a measurement, a prescribed brace, a doctor’s opinion linking it to service.
