Anemia is not a single disease — it is a category of conditions defined by insufficient red blood cells or hemoglobin to carry adequate oxygen to the body's tissues. VA's rating schedule in 38 CFR Part 4, Subpart B addresses multiple distinct types of anemia, each under a specific diagnostic code in the hematological and lymphatic systems section (DC 7700–7716).
Understanding which type of anemia you have — and which DC applies — is essential for claiming the correct rating. The most common types veterans encounter:
VA rates hypochromic-microcytic anemia under Diagnostic Code 7700. This code covers iron deficiency anemia and other microcytic anemias characterized by small, pale red blood cells and low hemoglobin. The rating is based primarily on hemoglobin levels and the need for transfusion:
| Rating | Criteria |
|---|---|
| 100% | Hemoglobin consistently 5 grams or less, or requires transfusion |
| 70% | Hemoglobin consistently 7 grams or less, with findings of cardiac hypertrophy or dilation |
| 50% | Hemoglobin consistently less than 8 grams, or other findings of chronic disease |
| 30% | Hemoglobin consistently 8-10 grams |
| 10% | Hemoglobin consistently 10-11 grams |
| 0% | Diagnosis confirmed, hemoglobin above 11 grams, no compensable findings |
VA looks for a consistent pattern of low hemoglobin, not a single abnormal reading. A one-time low result during an acute illness may not be sufficient. Submit multiple lab results over time showing persistent anemia — quarterly or more frequent CBC results are ideal evidence. "Consistently" means the average level, not just the lowest individual reading.
Anemia of chronic disease (ACD) — also called anemia of inflammation — is the most prevalent anemia type in veterans with multiple service-connected conditions. It occurs when chronic inflammatory processes (cancer, infection, autoimmune disease, kidney disease) interfere with iron utilization and red blood cell production. ACD often shows up as a normocytic-normochromic anemia (normal-sized, normal-color cells) or mild microcytic anemia, and it is typically rated under DC 7700 or by analogy if another code fits better.
Sickle cell conditions affect a disproportionate number of veterans of African descent. VA rates these under two specific codes:
Sickle cell anemia is caused by inheriting two copies of the sickle hemoglobin gene (HbSS genotype). Veterans with this condition experience periodic painful crises when sickled cells obstruct blood flow, as well as chronic organ damage from repeated sickling. Ratings under DC 7714:
| Rating | Criteria |
|---|---|
| 100% | Requiring frequent hospitalizations, or with severe complication (e.g., stroke, acute chest syndrome, organ failure) |
| 50% | With crisis requiring hospitalization at least twice per year, or with chronic complications such as leg ulcers or bone changes |
| 30% | With one or two sickle cell crises per year requiring hospitalization |
| 10% | With pain episodes not requiring hospitalization but significantly affecting daily function |
| 0% | Confirmed diagnosis; asymptomatic or minimally symptomatic periods |
Sickle cell trait (HbAS genotype — one sickle gene, one normal) is rated at 0% — meaning the diagnosis is recognized and a service-connected rating is assigned, but no compensation is paid. However, if a veteran with sickle cell trait develops complications attributable to the trait (which can occur under conditions of extreme exertion, altitude, or dehydration — all common in military service), a higher rating may be argued with medical evidence.
Sickle cell anemia and trait are hereditary — you are born with them. VA service connection for a hereditary condition typically covers situations where the condition was aggravated by military service beyond its natural progression. If your sickle cell disease worsened during service — more frequent crises, earlier organ complications, or new organ damage — you may be entitled to a rating for the degree of aggravation under 38 CFR § 3.306.
| DC | Condition | Notes |
|---|---|---|
| 7704 | Pernicious anemia (B12 deficiency) | Rated by analogy with other anemias; requires documentation of autoimmune gastritis or gastrectomy cause |
| 7705 | Hemolytic anemia | Non-service-specific; rated based on severity similar to DC 7700 |
| 7706 | Aplastic anemia | Severe bone marrow failure; typically 100% during treatment; rated residually after stem cell transplant |
| 7716 | Myelodysplastic syndromes | Bone marrow failure with potential for transformation to leukemia; may be rated as neoplasm |
The following table summarizes rating levels across the major anemia diagnostic codes for quick reference:
| DC | Type | 100% | 70% | 50% | 30% | 10% |
|---|---|---|---|---|---|---|
| 7700 | Hypochromic-microcytic | Hgb ≤5g or transfusion | Hgb ≤7g + cardiac findings | Hgb <8g | Hgb 8-10g | Hgb 10-11g |
| 7714 | Sickle cell | Frequent hosp. / severe complications | — | ≥2 crises/year hosp. | 1-2 crises/year hosp. | Pain episodes, no hosp. |
| 7706 | Aplastic anemia | During active treatment | Residuals rated post-transplant | |||
Anemia can reach VA service connection through three pathways:
Direct service connection applies when anemia began during military service or was caused by a specific in-service event or exposure. Examples:
Secondary service connection is the most common pathway for anemia in veterans. Under 38 CFR § 3.310, if an existing service-connected condition causes or aggravates anemia, the anemia can be rated as secondary. Common secondary anemia pathways are detailed in the sections below.
Gulf War veterans may be able to establish service connection for certain hematological abnormalities, including persistent anemia, under the Gulf War illness presumptive framework at 38 CFR § 3.317 — if the anemia is part of a chronic multisymptom illness with no other identifiable cause, has manifested to a compensable degree within the applicable timeframe, and other requirements are met.
Chemotherapy-induced anemia is one of the most prevalent forms of anemia in veterans with service-connected cancers. Cytotoxic chemotherapy suppresses bone marrow activity, reducing red blood cell production. Specific agents with high anemia risk include:
For veterans who have service-connected cancers (lung, prostate, bladder, breast, lymphoma, leukemia, etc.) and received chemotherapy, the resulting anemia is directly traceable to the service-connected cancer treatment. File it as secondary under 38 CFR § 3.310. Your oncologist's records documenting chemotherapy type, schedule, and CBC results showing anemia are the primary evidence.
See our Endometrial Cancer VA Disability guide for an example of how cancer residuals — including anemia — are claimed after active cancer treatment.
Anemia of chronic disease (ACD) — also called anemia of inflammation — occurs when the body's inflammatory response disrupts normal iron metabolism and erythropoiesis (red blood cell production). The mechanism: inflammatory cytokines (IL-6, TNF-α, IL-1β) stimulate hepcidin production, which sequesters iron in macrophages and blocks iron absorption. The result is functional iron deficiency even when iron stores are normal.
For anemia secondary to service-connected chronic kidney disease, the connection is especially direct: the kidneys' EPO-producing cells are damaged, reducing the hormonal stimulus for red blood cell production. This is a well-established, commonly accepted secondary claim.
Veterans who served in the Southwest Asia theater during and after the 1990-1991 Gulf War and subsequent operations face a range of potential toxic exposures that may contribute to hematological conditions:
Open-air burn pits used to incinerate waste in Iraq, Afghanistan, and other deployment locations released benzene, dioxins, and other myelotoxic chemicals. Benzene is a well-established cause of bone marrow suppression, aplastic anemia, and secondary leukemia. Veterans with significant burn pit exposure who develop aplastic anemia or myelodysplastic syndrome may pursue PACT Act service connection.
Pesticides used in Gulf War theater (permethrin-treated uniforms, flea and tick collars, DEET) and potential nerve agent precursor exposures have been associated with hematological effects in some veterans. If you believe your anemia is related to chemical exposures during Gulf War service, a private medical opinion addressing the specific exposure-to-anemia pathway is essential.
Under 38 CFR § 3.317, Gulf War veterans can receive presumptive service connection for chronic multisymptom illnesses — including functional hematological abnormalities — when no other cause is identified. Anemia as part of a broader chronic fatigue/immune dysfunction pattern in Gulf War veterans has been recognized in some claims under this framework, though it is not a listed specific presumptive condition.
