The Department of Veterans Affairs (VA) rates Immune Thrombocytopenia (ITP) under 38 CFR § 4.117, Diagnostic Code 7705, from 0% to 100%. In the guides we publish here, we walk through each tier next to the evidence a claim needs, because the platelet number alone rarely tells the whole story.
Title 38 of the Code of Federal Regulations (CFR) ties that number to two factors together: platelet count, and the treatment your doctors have used to control bleeding. A splenectomy adds a separate rating on top of the platelet-based one, and the 100% rating carries its own rules once chemotherapy ends.
What Is Immune Thrombocytopenia (ITP)?
Immune Thrombocytopenia (ITP) is an autoimmune blood disorder in which the immune system attacks and destroys the body's own platelets, the blood cells that let a cut or injury clot. A low platelet count raises the risk of bruising, nosebleeds, bleeding gums, and in severe cases internal bleeding that needs emergency treatment. Doctors manage it with corticosteroids, immune globulin, immunosuppressive drugs, or spleen removal.
ITP can show up during active duty, surface years later, or develop as a side effect of a medication or another condition you're already being treated for. That timing matters a great deal once a claim moves into the evidence and nexus stage.
How the VA Rates ITP Under Diagnostic Code 7705
The VA rates ITP on a five-tier schedule that combines platelet count with the treatment your doctors have had to use to control it. A higher platelet count with no treatment sits at the bottom of the schedule. A count that stays low despite aggressive treatment, or that requires chemotherapy, sits at the top.
| Rating | Criteria |
|---|---|
| 100% | Requiring chemotherapy for chronic refractory thrombocytopenia, or a platelet count of 30,000 or below despite treatment. |
| 70% | Requiring immunosuppressive therapy, or a platelet count higher than 30,000 but not higher than 50,000 with a history of hospitalization for severe bleeding that required intravenous immune globulin, high-dose parenteral corticosteroids, and platelet transfusions. |
| 30% | Platelet count higher than 30,000 but not higher than 50,000, with either immune thrombocytopenia or mild mucous membrane bleeding that requires oral corticosteroid therapy or intravenous immune globulin. |
| 10% | Platelet count higher than 30,000 but not higher than 50,000, not requiring treatment. |
| 0% | Platelet count above 50,000 and asymptomatic, or immune thrombocytopenia in remission. |

What the Platelet Count Thresholds Mean
A platelet count by itself only sets a ceiling on the rating, not the final number. Two veterans with the same lab result can land on different tiers depending on what their treatment record shows. The 30,000 to 50,000 range spans three separate ratings, 10%, 30%, and 70%. Treatment decides which of the three applies to you.
If you're in that range and need no treatment, you sit at 10%. Add oral corticosteroids or intravenous immune globulin for mild mucous membrane bleeding and the same count moves to 30%. Add a hospitalization for severe bleeding that required transfusions and it moves to 70%, even though the platelet number never changed.
What we see readers get wrong most often is assuming VA looks only at the lowest lab value on file. VA reads the whole treatment record instead. A claim built around one favorable platelet count, with no supporting treatment history, usually comes back lower than you expected.
Splenectomy and Diagnostic Code 7706
A splenectomy performed to treat ITP gets its own separate rating, not folded into the DC 7705 number. Note 1 of the regulation directs the VA to evaluate a splenectomy under Diagnostic Code 7706, rated at 20%. That rating then combines with the DC 7705 evaluation using VA's combined ratings table, not simple addition.
If you had a splenectomy and still have a qualifying platelet count or treatment burden, you can carry both ratings at once.
How VA Re-Exams and Reduces a 100% ITP Rating
A 100% rating for chronic refractory thrombocytopenia does not end the day chemotherapy stops. Note 2 of the regulation keeps the 100% evaluation in place through the end of treatment and beyond it. Six months after chemotherapy ends, the VA schedules a mandatory examination to re-determine the rating based on the platelet count and symptoms at that point.
If that exam supports a lower rating, any reduction still has to follow the standard due-process protections in 38 CFR § 3.105(e). Those protections require written notice and a chance to submit evidence first. Our 38 CFR rating schedule explainer covers how VA's reduction rules work across every diagnostic code, not just ITP.
Evidence and the Nexus Requirement for ITP Service Connection
Service connection for ITP requires three things on file: a current diagnosis, an in-service event or aggravating factor, and a medical nexus opinion linking the two. Without all three, the claim usually gets denied even when the diagnosis itself is not in dispute.
- Service treatment records showing a platelet count drop, unexplained bruising, or a bleeding episode during active duty.
- A current diagnosis from a hematologist, with recent platelet counts and the treatment history behind them.
- A nexus letter from a treating physician connecting the in-service event to the current diagnosis, written in terms of "at least as likely as not."
- Buddy statements describing bruising, fatigue, or bleeding episodes a service member noticed but never reported through medical channels at the time.
ITP can also reach service connection secondarily, meaning it developed because of a condition already service-connected rather than an event during service itself. Long-term steroid or immunosuppressive treatment for another condition, certain infections, and some autoimmune disorders all have documented links to secondary thrombocytopenia in the medical literature. The specific mechanism still has to be established by a treating provider's nexus opinion in each individual case.
VA does not assume a link from a general medical association alone. Our secondary conditions lookup tool is built for exactly this step, matching an already-rated condition to the secondary conditions VA most often connects to it.
Secondary Conditions Linked to ITP
ITP itself can also become the starting point for other secondary claims rather than only the endpoint of one. Long-term corticosteroid treatment carries its own documented side effects, including bone density loss, weight gain, and mood changes. Your doctor may diagnose these separately and connect them back to the ITP treatment plan.
Chronic fatigue and anemia from repeated bleeding episodes are two more conditions you might raise as secondary to ITP once the primary rating is in place.
None of these secondary conditions get rated automatically. Each one needs its own diagnosis and its own nexus opinion tying it back to the service-connected ITP or its treatment. File it as a separate claim, or add it to an existing one.
When Severe ITP Supports a TDIU Claim
Total Disability based on Individual Unemployability (TDIU) pays you at the 100% rate even when no single condition is individually rated at 100%. It applies when your service-connected conditions together prevent you from holding substantially gainful employment. If you're rated at 70% for ITP under DC 7705, you may meet the schedular threshold, especially when secondary conditions like chronic fatigue or anemia are also rated.
The bleeding risk and hospitalization history behind a 70% ITP rating can itself be the reason a job becomes unmanageable, particularly in physical or safety-sensitive occupations. Our TDIU explained guide walks through the schedular and extraschedular paths in full, including the evidence VA looks for in an unemployability claim.
How to File a VA Claim for ITP
Filing starts with the same evidence file described above, then moves through VA's standard claims process from there.
- Confirm the current diagnosis and gather at least a year of platelet count and treatment records from the treating hematologist.
- Pull service treatment records and any private medical records that document symptoms or a diagnosis during service.
- Get a nexus opinion, direct or secondary, from a physician willing to state the connection in VA's required language.
- File the claim through VA.gov's disability claim system, attaching every piece of supporting evidence up front rather than waiting for a request.
- Attend the scheduled Compensation and Pension (C&P) exam and bring a current treatment summary the examiner can reference.
Check the full VA disability conditions list to see how ITP fits alongside other blood and immune system conditions. Once a decision letter arrives, run the rating through the VA disability rating calculator to see how it affects a combined rating.
If the claim involves back pay from an earlier effective date, our VA disability back pay guide explains how VA calculates what is owed. Start the claims file now, while the treatment records are still easy to pull together.
