This reference uses VA rating codes. For a code from a medical record, check ICD-10-CM and the service date. A clinical code alone does not establish a VA rating or a matching VA diagnostic code.
Histoplasmosis of lung
Respiratory · 38 CFR § 4.97
Diagnostic Code 6834 is the VASRD entry for Histoplasmosis of lung. VA applies the controlling criteria, shared formulas, and special instructions shown in 38 CFR Part 4. VMC presents this material for education and reference; it does not determine a Veteran's diagnosis, service connection, or evaluation.

Source-verified VASRD criteria
How VA rates this — General Rating Formula for Mycotic Lung Disease (diagnostic codes 6834 through 6839)
These percentages summarize the regulatory criteria already mapped to this diagnostic code. They do not predict a Veteran's individual evaluation or establish service connection.
Chronic pulmonary mycosis with persistent fever, weight loss, night sweats, or massive hemoptysis
Chronic pulmonary mycosis requiring suppressive therapy with no more than minimal symptoms such as occasional minor hemoptysis or productive cough
Chronic pulmonary mycosis with minimal symptoms such as occasional minor hemoptysis or productive cough
Healed and inactive mycotic lesions, asymptomatic
Special rating instructions
- General Rating Formula for Mycotic Lung Disease (diagnostic codes 6834 through 6839):
- Restrictive Lung Disease
Regulatory notes
- 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.

Evidence information
When reviewing the criteria, useful evidence categories can include diagnosis and treatment records, objective testing identified by the schedule, documented frequency/duration/severity when the criteria use those concepts, and functional effects described in medical or lay evidence. The relevant evidence depends on the actual claim and medical facts.
VMC does not diagnose conditions, guarantee a percentage, or advise anyone to exaggerate symptoms.
