HPA Axis Dysfunction

DC 7999-7903Endocrine38 CFR 4.119, DC 7999-7903

A condition where the connection between your brain and adrenal glands is not working properly, often caused by long-term steroid use for a service-connected condition. Your body cannot produce enough cortisol on its own. Symptoms include fatigue, weakness, low blood pressure, and risk of adrenal crisis. The VA rates this based on your need for hormone replacement and how often you have crisis episodes.

How the VA rates this condition

The VA rates this condition based on the type and intensity of treatment you require. Higher ratings correspond to more aggressive treatment regimens, such as daily medication, insulin dependence, or the need for ongoing medical management.

Diagnostic code

DC 7999-7903

Rating range

10% – 60%

Rating levels

Rating criteria are defined in 38 CFR 4.119, DC 7999-7903. This guide presents a plain-language summary and is not a substitute for the full regulatory text. Always consult a VSO or VA-accredited attorney for case-specific advice.

Rating Levels

Your HPA axis dysfunction requires high-dose hormone replacement and you have multiple adrenal crisis episodes per year requiring emergency treatment or hospitalization, significantly limiting your daily activities.

What the VA looks for

High-dose hormone replacement therapy
Multiple adrenal crises requiring ER or hospitalization
Stress-dose steroid protocols documented
Significant daily activity limitations
Emergency injection kit prescribed (Solu-Cortef)
Endocrinologist management records

Common Pitfalls

⚠Not connecting to the steroid medication that caused it — the most common cause is long-term corticosteroid use for a service-connected condition (asthma, arthritis, skin conditions). Get a nexus letter explaining how the steroids suppressed your HPA axis.
⚠Not getting proper diagnostic testing — an ACTH stimulation test is the gold standard for diagnosing HPA axis dysfunction. Morning cortisol levels alone may not be enough.
⚠Not documenting "stress dosing" needs — if you need to increase your steroid dose during illness, surgery, or physical stress, this shows the severity of your condition.
⚠Not carrying medical alert identification — ask your doctor to document that you need a medical alert bracelet. This supports the seriousness of your condition for VA rating purposes.
⚠Not tracking every crisis episode — each time you need emergency treatment for adrenal insufficiency, it should be documented. This directly affects your rating level.
