Understanding VA Disability Ratings
Learn how the VA assigns disability ratings, how multiple conditions are combined, and how your rating translates to monthly compensation.
What a Rating Represents
VA disability ratings reflect the average impairment in earning capacity caused by your service-connected conditions. Ratings are assigned in 10% increments from 0% to 100%.
Important: 0% is Still a Win
A 0% rating means you're service-connected. This is crucial because:
- You can file for an increase if your condition worsens
- You can claim secondary conditions
- You qualify for VA healthcare for that condition
- Time-based protections start accruing
The Rating Schedule
VA uses the Schedule for Rating Disabilities (38 CFR Part 4) to determine ratings. Each condition has a diagnostic code with specific criteria for each rating level.
Major Body Systems in the Schedule
- Musculoskeletal: Bones, joints, muscles, spine
- Mental Disorders: PTSD, depression, anxiety, TBI
- Respiratory: Sleep apnea, asthma, lung conditions
- Cardiovascular: Heart conditions, hypertension
- Digestive: GERD, IBS, liver conditions
- Neurological: Nerve damage, seizures, headaches
- Skin: Eczema, psoriasis, scars
- Endocrine: Diabetes, thyroid conditions
- Genitourinary: Kidney, bladder, reproductive conditions
- The Senses: Vision, hearing, tinnitus
Don't Misuse the Schedule
The rating schedule is for understanding how VA evaluates conditions—NOT a checklist of symptoms to claim. Misrepresenting your condition is fraud and a federal crime.
VA Math: Combining Multiple Ratings
VA does NOT add ratings together. Instead, they use "VA Math" (combined ratings table), which considers your remaining "healthy" capacity after each disability.
How VA Math Works
- Start with your highest rating
- Apply the next highest rating to the remaining percentage
- Continue until all ratings are applied
- Round to the nearest 10%
Example: 50% + 30% + 20%
| Start with | 100% (whole body) |
| Apply 50% | 100% - 50% = 50% remaining |
| Apply 30% to remaining | 50% × 30% = 15%, so 50% - 15% = 35% remaining |
| Apply 20% to remaining | 35% × 20% = 7%, so 35% - 7% = 28% remaining |
| Combined disability | 100% - 28% = 72% → rounds to 70% |

The Pyramiding Rule
The same symptom cannot be rated twice. This is called the "pyramiding rule" (38 CFR 4.14).
Example: If you have two ankle conditions that both limit range of motion, you can't get separate ratings based on limited motion for each diagnosis—the symptom (limited motion) can only be rated once.
Common Pyramiding Errors
Sometimes VA incorrectly rates the same symptom twice. If you have both of the following rated separately, consult a VSO before filing new claims:
- Sleep apnea AND asthma
- Median nerve AND ulnar nerve (same arm)
- PTSD AND TBI (unless symptoms are differentiated)
The Amputation Rule
Your combined rating for musculoskeletal conditions of a limb cannot exceed what you'd receive if the limb were amputated.
Example: If amputation above the elbow of the dominant arm is rated at 80%, your combined rating for elbow, forearm, wrist, and hand conditions on that arm cannot exceed 80%.
Special Rating Situations
Temporary 100% for Hospitalization (38 CFR 4.29)
If you're hospitalized at a VA or approved hospital for 22+ continuous days for a service-connected condition, you receive 100% pay during that time.
Convalescent Rating (38 CFR 4.30)
Following surgery on a service-connected condition, you may qualify for temporary 100% if you need:
- At least 1 month of recovery
- Immobilization of a major joint
- House confinement
- Use of a wheelchair or crutches
Extraschedular Ratings (38 CFR 3.321(b))
In exceptional cases with marked interference with employment or frequent hospitalizations, VA may grant a rating higher than the schedule provides. These are rare.
Rating Protections
Your ratings gain legal protections over time:
5-Year Rule (38 CFR 3.344)
After a rating has been in effect for 5 continuous years, it generally cannot be reduced based on a single exam showing improvement. Continuous improvement must be demonstrated.
10-Year Rule (38 CFR 3.957)
After 10 years, service connection cannot be severed (except for fraud or proof you didn't have qualifying service).
20-Year Rule (38 CFR 3.951)
After 20 years at a rating level, that rating cannot be reduced (except for fraud).
Protection Timing
Time-based protections start from the effective date of the grant, NOT the date of the rating decision.
Static vs. Non-Static Conditions
Some conditions are rated as "static" (unlikely to improve), while others may require future re-examinations.
Conditions that typically require re-exams:
- Active cancers
- Conditions with mandatory re-evaluation periods per the rating schedule
Currently, VA is rating most conditions as static out of the gate, reducing future re-exam requirements.
Understanding Your Decision Letter
Your rating decision will show:
- Service-connected conditions: Each condition and its individual rating
- Combined rating: Your overall disability percentage
- Effective dates: When each rating began
- Monthly payment: Based on your combined rating and dependents
