Veterans who contracted COVID-19 during active military service or while on qualifying active duty orders may establish service connection for Long COVID conditions. Chronic fatigue, POTS, cognitive impairment, and cardiac complications can each be rated — some at 30–60% or higher — adding hundreds of dollars per month in benefits. The key is proving your COVID was service-connected and documenting the persistent residuals.
Long COVID — formally known as Post-Acute Sequelae of SARS-CoV-2 Infection (PASC), ICD-10 code U09.9 — refers to persistent symptoms that continue for more than 4 weeks after the initial COVID-19 infection. The WHO defines Long COVID as symptoms that occur 3 months after the onset of COVID-19, last at least 2 months, and cannot be explained by an alternative diagnosis.
For veterans, Long COVID is a significant emerging disability category. Tens of thousands of service members contracted COVID-19 during the pandemic period of 2020–2023, many while on active duty, deployed, or on qualifying military orders. Those who developed persistent post-COVID symptoms have a potentially valid service connection claim — but it requires careful documentation of both the initial COVID infection during service AND the current persisting conditions.
Service connection for Long COVID follows the standard three-element framework for direct service connection under 38 CFR § 3.303:
The "in-service event" element is established by documentation of a positive COVID test (PCR, antigen, or antibody) in your service medical records (SMR), sick call visit documenting COVID-19 diagnosis, hospitalization records, or any official military documentation of COVID diagnosis during your service period.
Under 38 CFR § 3.303(b), veterans who cannot document a clean chain from in-service COVID to current Long COVID may establish service connection through continuity of symptomatology — showing that symptoms have persisted continuously since the in-service event without significant interruption.
This requires:
Service connection for Long COVID requires that the initial COVID-19 infection occurred during qualifying active service. The following service contexts qualify:

Post-COVID ME/CFS is one of the most debilitating Long COVID manifestations. Veterans with post-COVID fatigue that meets CDC diagnostic criteria (post-exertional malaise, unrefreshing sleep, cognitive impairment, orthostatic intolerance) may be rated under DC 6354 (chronic fatigue syndrome) at 10–100% based on functional impairment. The Gulf War CFS framework under 38 CFR § 3.317 may also apply for Gulf War veterans.
POTS — characterized by heart rate increases of ≥30 bpm upon standing, accompanied by lightheadedness, palpitations, and pre-syncope — affects 2–14% of Long COVID patients. POTS is rated under DC 7010 (supraventricular dysrhythmias) or analogous codes based on severity. A tilt table test confirming POTS provides the objective diagnostic evidence needed for the claim.
Post-COVID cognitive impairment — including memory deficits, processing speed slowing, attention difficulties, and word-finding problems — can be rated under DC 8045 (traumatic brain injury) analogously, or under the mental disorders rating schedule if it meets criteria for cognitive disorder. Neuropsychological testing documenting the specific cognitive domains affected provides the objective evidence.
Veterans with post-COVID pulmonary fibrosis, reduced lung capacity, or ongoing respiratory dysfunction may be rated under the pulmonary rating schedule (DC 6600–6843) based on spirometry (FEV-1, FVC, DLCO).
Post-COVID myocarditis, pericarditis, or cardiomyopathy can cause lasting cardiac dysfunction. These are rated under the cardiovascular rating schedule — myocarditis under DC 7007, cardiomyopathy under DC 7007 analogously, based on ejection fraction and functional capacity.
New or worsened sleep disorders following COVID-19, including insomnia and sleep apnea, may be ratable as secondary to a service-connected COVID infection.
Because Long COVID is a newer condition, VA raters often use analogous rating codes under 38 CFR § 4.20 — applying the diagnostic criteria from the closest existing condition. The VA is required to rate a veteran's disability even when there is no specific diagnostic code for the exact condition:
| Long COVID Condition | Analogous DC Used | Key Rating Criteria |
|---|---|---|
| Chronic fatigue / ME-CFS | DC 6354 | Functional impairment, episodes of acute exacerbation, ability to work |
| POTS / dysautonomia | DC 7010 / DC 7101 | Heart rate response, syncope, functional limitation |
| Cognitive impairment | DC 8045 / DC 9304 | Neuropsychological testing, cognitive domains affected |
| Pulmonary fibrosis | DC 6825 | FVC and DLCO percentages from PFT |
| Post-COVID cardiomyopathy | DC 7007 | Ejection fraction, METs capacity |
| Sleep apnea (new onset) | DC 6847 | CPAP requirement = 30% |
| Depression/anxiety (post-COVID) | DC 9434 / 9413 | GAF/WHODAS criteria, functional impairment |
Yes — for most Long COVID claims, a nexus letter is required. Long COVID is not a presumptive condition with automatic service connection. You need a physician's opinion establishing the nexus between your in-service COVID infection and your current Long COVID conditions.
The nexus letter should:
An internal medicine physician, infectious disease specialist, or a post-COVID clinic physician is ideally positioned to write this nexus opinion. Post-COVID specialty clinics at major medical centers have clinicians experienced in documenting Long COVID for disability purposes.
Request a Nexus Letter for Long COVID →Request your complete service medical records through the National Personnel Records Center (NPRC) or MyHealtheVet. If COVID testing was done at a military treatment facility (MTF), those records should show the diagnosis. Some Reserve and Guard members' COVID tests may be in state health records — gather these as well.
The most common reason for Long COVID VA denials is an inadequate nexus. A C&P examiner who provides a negative nexus without addressing the scientific literature on Long COVID pathophysiology can be challenged on appeal. Obtain a strong nexus letter from a Long COVID specialist and submit it as a supplemental claim.
Long COVID symptoms need to be formally diagnosed, not just noted as symptoms. "Fatigue" is not a claim — "ME/CFS meeting CDC diagnostic criteria" is a claim. Work with your physician to ensure each condition has a specific ICD-10 diagnosis code in your medical records before filing.
