VA Disability Rating System

The VA disability rating system — governed by 38 U.S.C. Chapter 11 and the 38 CFR Part 4 Schedule for Rating Disabilities (VASRD) — assigns veterans a percentage rating from 0% to 100% (in 10% increments) for each service-connected disability, determining tax-free monthly compensation ranging from approximately $180.97/month (10%) to $3,938.58/month (100%) for a single veteran (2026 rates after the 2.8% COLA effective Dec 1, 2025; with additional amounts for dependents at 30%+). Over 6.4 million veterans receive disability compensation. The critical non-obvious rule: combined ratings are not simple addition. If you have a 60% rating for one condition and a 40% for another, the VA calculates the second rating against the remaining 40% of "whole person" — yielding a combined 76%, which rounds to 80%, not 100%. The PACT Act (2022) was the most significant expansion of veteran benefits in decades, adding presumptive service-connection for veterans exposed to burn pits, Agent Orange, and other toxic substances — making hundreds of thousands of previously-denied claims eligible without requiring veterans to prove a causal link. Despite this expansion, the VA maintains a backlog of over 600,000 pending initial claims (2025). Veterans with 10%+ disability ratings receive compensation tax-free; those rated 30%+ also qualify for dependency allowances, commissary access, and VA healthcare priority group upgrades.

Current Law (2026)

Legal Authority

• 38 U.S.C. § 1110 — Basic entitlement (for disability resulting from personal injury suffered or disease contracted in the line of duty during wartime service, VA shall pay compensation)
• 38 U.S.C. § 1112 — Presumptions relating to certain diseases (veterans with 90+ days of wartime service who develop chronic diseases within presumptive periods are presumed service-connected; includes arthritis, diabetes, cardiovascular disease, and many others)
• 38 U.S.C. § 1113 — Presumptions rebuttable (presumptions of service connection can be rebutted by affirmative evidence showing the disease was not incurred in service)
• 38 U.S.C. § 1114 — Rates of wartime disability compensation (sets compensation rates for each rating level from 10% to 100%; Special Monthly Compensation rates for specific severe disabilities — loss/loss of use of extremities, blindness, deafness, anatomical loss)
• 38 U.S.C. § 1116 — Agent Orange presumptions (veterans who served in Vietnam and certain other locations and develop specified diseases are presumed service-connected; diseases include type 2 diabetes, ischemic heart disease, Parkinson's, several cancers, and others)
• 38 U.S.C. § 1117 — Gulf War illness (compensation for undiagnosed illness and medically unexplained chronic multi-symptom illness in Persian Gulf War veterans)
• 38 U.S.C. § 1131 — Peacetime disability (same compensation for disability incurred during peacetime service)
• 38 U.S.C. § 1151 — Benefits for VA treatment injuries (compensation for disability caused by VA hospital care, medical treatment, or vocational rehabilitation — no service connection required)
• 38 U.S.C. § 1153 — Aggravation (pre-existing conditions aggravated by military service are compensable)
• 38 U.S.C. § 1154 — Consideration of combat circumstances (for combat veterans, VA accepts lay evidence consistent with the circumstances of service to establish that an injury occurred, even without official records)
• 38 U.S.C. § 1155 — Authority for the rating schedule (Secretary establishes a schedule for rating reductions in earning capacity from specific injuries/diseases; ratings represent average impairment in earning capacity)

How It Works

The VA disability rating system determines how much monthly compensation veterans receive for injuries and illnesses connected to their military service. It is one of the largest federal benefit programs, serving over 5 million veterans.

Establishing service connection is the threshold step. Under 38 U.S.C. § 1110, a veteran must show three elements: a current disability, an in-service event or disease, and a nexus between the two — supported by service medical records, VA examinations, private medical opinions, or buddy statements. For combat veterans, § 1154(b) relaxes the standard: VA must accept lay evidence consistent with the circumstances of service without independent corroboration. Once service connection is established, VA assigns a rating from 0% to 100% in 10% increments using the Schedule for Rating Disabilities (38 CFR Part 4), organized by body system. Each diagnostic code specifies criteria for each tier — PTSD (DC 9411), for example, runs from 0% (diagnosed but not interfering with functioning) through 10% (mild symptoms with mild occupational/social impairment) to 100% (total occupational and social impairment). Ratings represent average impairment in earning capacity, not the individual veteran's actual income loss.

Most veterans have multiple service-connected conditions, and the combined ratings table does not add percentages directly. VA uses a "whole person" method: start with the highest rating, then apply the next rating to the remaining healthy percentage. A 50% and a 30% rating combine to 65% (not 80%) — and 65% rounds to 70%. For certain conditions, VA presumes service connection without requiring individual nexus proof: Agent Orange presumptives (§ 1116) cover type 2 diabetes, ischemic heart disease, Parkinson's, several cancers, and others for Vietnam-era veterans; Gulf War illness (§ 1117) covers undiagnosed chronic multi-symptom illness; and the PACT Act (2022) added presumptive coverage for burn pit exposures and dozens of additional cancers. Veterans who cannot maintain substantially gainful employment due to service-connected disabilities but lack a 100% schedular rating can receive compensation at the 100% rate ($3,938.58/month, 2026) through TDIU (Total Disability Individual Unemployability) — requiring one disability at 60%+ or combined ratings of 70%+ with one condition at 40%+. Veterans with severe specific disabilities (loss of a hand, foot, or eye; need for aid and attendance) may also qualify for Special Monthly Compensation (SMC), structured in categories K through S with rates above the basic 100% tier.

State Variations

Implementing Regulations

• 38 CFR Part 4 — Schedule for Rating Disabilities (92 sections; implementing 38 U.S.C. § 1155; the single most important regulation for veterans with service-connected conditions — it defines every percentage rating that drives disability compensation payments; most recent significant amendment: 89 FR 33, 2024 updates to musculoskeletal and mental health rating criteria under the VA MISSION Act):

  Core rating principles (Subpart A, §§ 4.1–4.31):

  • § 4.1 — Essentials of evaluative rating: the rating schedule is a guide for evaluating disability from diseases and injuries incident to military service; percentage ratings represent the average impairment in earning capacity, not the individual veteran's actual income loss — VA rates conditions based on typical impact, not whether a specific veteran is economically harmed
  • § 4.2 — Interpretation of examination reports: when different examiners describe the same condition differently over time, VA must interpret reports consistently and give the veteran the benefit of any ambiguity in the medical record
  • § 4.3 — Reasonable doubt: when there is an approximate balance of positive and negative evidence, the benefit of the doubt is given to the veteran — this is a statutory mandate, not VA discretion
  • § 4.7 — Higher evaluation: where the evidence is in approximate balance between two rating percentages, the higher evaluation will be assigned
  • § 4.10 — Functional impairment: the basis of disability evaluation is the ability of the body, psyche, or organ system to function under ordinary conditions including employment; the rating measures the functional impact of the condition, not its clinical severity alone
  • § 4.14 — Avoidance of pyramiding: the same disability cannot be evaluated under multiple diagnostic codes to inflate the rating; where an injury affects muscles, nerves, and joints of the same extremity, special rules prevent double-counting the same functional loss
  • § 4.15 — Total disability ratings: total disability is based on the economic or industrial handicap the veteran must overcome, not individual circumstances; the schedule aims for uniform treatment across similar conditions

  Unemployability and total disability (§§ 4.16–4.19):

  • § 4.16(a) — TDIU (individual unemployability): total disability rating may be assigned when the schedular rating is less than 100% if the veteran cannot secure or follow substantially gainful employment due to service-connected disabilities; single disability must be at least 60%, or combined disabilities at least 70% combined with at least one rated 40%
  • § 4.16(b) — Extraschedular TDIU: veterans who don't meet the 60%/70% threshold may still receive TDIU if their case is submitted to the VA's Director of Compensation for extraschedular consideration — covers rare cases where individual circumstances are exceptional
  • § 4.18 — Unemployability: a veteran may be considered unemployable on termination of employment where special consideration was given on account of the disability, when it is shown they cannot secure further employment; volunteer work and sheltered employment generally don't preclude unemployability
  • § 4.19 — Age in service-connected claims: age may NOT be considered in evaluating service-connected disability; advancing age or age-related conditions cannot reduce a service-connected rating or serve as the basis for denying TDIU

  Combined ratings and bilateral factor (§§ 4.20–4.26):

  • § 4.20 — Analogous ratings: when a condition is not listed in the schedule, VA rates it under the closest related condition whose anatomical location, functions affected, and symptomatology are analogous; guesswork and conjectural analogies are prohibited
  • § 4.25 — Combined ratings table: VA does not simply add percentages; each additional disability is applied against the veteran's remaining efficiency — a 50% disability means 50% efficient, then a second 30% disability reduces efficiency by 30% of the remaining 50%, yielding a combined rating of 65% (not 80%); the table implements this "whole person" arithmetic
  • § 4.26 — Bilateral factor: when paired disabilities exist on both sides (both arms, both legs, or paired skeletal muscles), the combined rating of those bilateral conditions gets an additional 10% of that combined value added before further combination — recognizing that bilateral impairments cause proportionally greater functional loss than single-sided impairments

  Body system rating schedules (Subpart B, §§ 4.68–4.150):

  • § 4.71a — Musculoskeletal system: the most commonly rated body system; uses diagnostic codes 5000–5299; covers joints, muscles, bones, and spinal conditions; updated 2024 for knee and shoulder rating criteria
  • § 4.87 / 4.87a — Ear conditions and hearing impairment: tinnitus at Diagnostic Code 6260 is one of the most commonly service-connected conditions; rated 10% for tinnitus alone; hearing impairment uses audiometric testing under controlled conditions
  • § 4.97 — Respiratory system: rated by functional impairment using pulmonary function testing; COPD, asthma, sleep apnea, and sinusitis are among the most commonly rated respiratory conditions
  • § 4.104 — Cardiovascular system: heart conditions rated by METs (metabolic equivalents) of exertion before symptoms; heart failure, coronary artery disease, and hypertension have specific diagnostic codes; hypertension at DC 7101 is a top-10 claimed condition
  • § 4.114 — Digestive system: GERD, IBS, and Crohn's disease are commonly service-connected; ratings based on frequency of symptoms and functional impairment
  • § 4.118 — Skin: rated by percentage of body surface area affected, exposure, and required treatment frequency; eczema, psoriasis, and burn scars are common
  • § 4.119 — Endocrine system: diabetes mellitus (DC 7913) is one of the most commonly service-connected conditions for Vietnam veterans (Agent Orange presumptive) and Iraq/Afghanistan veterans; rated by required treatment level (insulin vs. oral agents) and complications
  • § 4.130 — Mental disorders: PTSD (DC 9411), major depressive disorder (DC 9434), and anxiety disorders are evaluated using the General Rating Formula for Mental Disorders — a functional scale ranging from 0% (asymptomatic) through 10%, 30%, 50%, 70%, and 100% based on occupational and social impairment; PTSD is the most commonly claimed mental health condition and one of the largest drivers of VA claims volume

Recent Developments

• The PACT Act (2022) was the largest expansion of VA healthcare and benefits in decades — adding 23 presumptive conditions related to toxic exposures (burn pits, Agent Orange, radiation) and removing the requirement to prove a nexus for these conditions
• VA claims backlog has grown significantly due to PACT Act claims volume — over 600,000 pending claims as of 2025
• VA has been modernizing the rating schedule (VASRD) by body system — updates to musculoskeletal, respiratory, and mental health rating criteria have been finalized or proposed
• The Appeals Modernization Act (2017) streamlined the appeals process, reducing average wait times for Board of Veterans' Appeals decisions
• Ongoing debate about whether the rating schedule adequately captures the impact of mental health conditions, particularly PTSD and traumatic brain injury
• In February 2026, VA amended 38 CFR 4.10 within the VA Schedule for Rating Disabilities to clarify the agency's longstanding interpretation regarding the impact of medication on evaluative ratings for disability compensation.
