Monoclonal Gammopathy of Undetermined Significance (MGUS)

DC 7709Hematologic/Lymphatic38 CFR 4.117, DC 7709

A pre-malignant condition where an abnormal protein (M-protein or paraprotein) is detected in the blood, produced by a small clone of plasma cells in the bone marrow. MGUS itself may not cause symptoms but requires lifelong monitoring because it can progress to multiple myeloma or other blood cancers. The VA rates MGUS based on its clinical impact.

How the VA rates this condition

The VA rates this condition based on the type, severity, and frequency of your symptoms. The examiner will evaluate your specific symptoms and how they affect your daily life and ability to work.

Diagnostic code

Rating range

0% – 30%

Rating levels

Rating criteria are defined in 38 CFR 4.117, DC 7709. 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 MGUS causes anemia, recurrent infections from immune paresis, or has features placing you at high risk for progression requiring closer surveillance and possible treatment.

What the VA looks for

Anemia attributed to MGUS
Recurrent infections from immune paresis
High-risk MGUS features documented
M-protein level approaching 3g/dL
Frequent monitoring visits and specialist care

Common Pitfalls

⚠Not filing a claim for MGUS because it is considered "pre-malignant" — establishing service connection now protects you if it progresses to multiple myeloma or lymphoma later, which would then be rated as secondary.
⚠Failing to document MGUS-associated peripheral neuropathy, which can be caused by the abnormal protein and is separately ratable — request nerve conduction studies and EMG testing.
⚠Not connecting MGUS to Agent Orange exposure, benzene, ionizing radiation, or other toxic exposures during military service — these are established risk factors for plasma cell disorders.
⚠Not maintaining consistent monitoring records showing the M-protein trend over time — a rising level supports disease progression and potentially higher ratings.
