Disability in the Armed Forces Discharge from active duty with or without compensation Permanent disability Temporary disability - Not fit for active duty - To be re-evaluated over time Discharge return to duty
Sources of Disability Data • Disability Agencies • Physical Evaluation Boards • Medical Evaluation Boards • Line-of-Duty Reports • Individual research reports
Identifying Injury-Related Disability • VASRD codes - diagnostic codes for a wide spectrum of diseases and physical impairments covering all major body systems • ICD-9-CM codes - diagnostic codes used to describe the nature of the medical condition and cause of an injury
Categories of Disability • Permanent disability – a permanent disability resulting in discharge with full compensation. • Separation with severance pay – disability resulting in discharge with separation pay. • Separation without benefits – disability resulting in discharge without pay • Temporary disability – a medical disability that could change over time; not fit for active duty • Fit for duty – return for active duty

Discussion The information reviewed suggests that: • Physical disability rates in the Armed Forces are at higher levels this decade than seen in the previous decade • 30% to 50% of disability cases could be due to injury • Most disability cases under review result in discharge from active service
Discussion [2] • Compensation for injury-related disability costs hundreds of millions of dollars • It is difficult to identify accurately the frequency and burden of injury-related disability in the Armed Forces from existing data sources
