VIII.iv.5.1.aDefinition: Chronic Disease
A chronic__disease is a disease
- of prolonged duration, producing incapacitating symptoms of varying degree
- that may undergo remission, and
- that is seldom entirely cured with all residuals of damage being completely eradicated.
VIII.iv.5.1.bEstablishing Whether a Disease Is Chronic
If a diagnosis is prefaced with the word “chronic,” that does not necessarily establish the disease as chronic. Important: Whether a disease is chronic is a matter for a factual determination dependent on the nature of the disease and its manifestations. Some diseases are inherently chronic, such as multiple sclerosis, while others, such as bronchitis, may be either acute or chronic.
VIII.iv.5.1.cConsidering SC for a Chronic Disease
When deciding any claim for service connection (SC) for a chronic under 38 CFR 3.309(a), it is also necessary to consider SC based on
- manifestation of the claimed disease during service, and
- a presumption that the disease, which was first manifested following discharge from service, is nevertheless related to service.
VIII.iv.5.1.dConsidering Presumptive SC
Once a substantially complete claim is of record, the following conditions apply:
- the possibility of entitlement to presumptive SC exists when the Veteran alleges inception within the limiting periods contained in 38 U.S.C. 1112
- the Veteran does not need to establish that the disease in question was definitely diagnosed within the presumptive period, and
- the evidence should show that manifestations of the condition, disabling to the degree of at least 10 percent, became apparent prior to the expiration of the presumptive period shown in 38 CFR 3.307.
VIII.iv.5.1.eEstablishing Presumptive SC for Chronic Diseases
Use the table below to determine the service requirements the Veteran must meet before VA may establish presumptive SC for chronic diseases listed in 38 CFR 3.309(a).
| If the Veteran served during … | Then … |
|---|---|
peacetime before January 1, 1947 | there is no provision for presumptive SC under 38 CFR 3.308(a). |
| the Veteran must have had active, continuous service of 90 days or more under 38 CFR 3.307. |
Note: In claims based on a period of active duty for training (ADT), there is no presumption of SC for chronic diseases under 38 CFR 3.309(a) (see Smith (Valerie Y.) v. Shinseki, 24 Vet.App. 40, 44 (2010)) unless SC has been established for a disability based on the period of ADT, as described in M21-1, Part III, Subpart i, 1.A.2.i.
VIII.iv.5.1.fAction to Take if a Chronic Disease Was Treated in Service

| If the Veteran ... | Then ... |
|---|---|
