Current DoD Roster of
Recent Veterans
• Evolving roster development by DoD Defense Manpower Data
Center (DMDC)
– In September 2003, DMDC developed an initial file of “separated” troops
who had been deployed to the Iraqi and Afghan theater of operations using
proxy files: Active Duty and Reserve Pay files, Combat Zone Tax
Exclusion, and Imminent Danger Pay data.
– In September 2004, DMDC revised procedures for creating periodic
updates of the roster and now mainly utilizes direct reports from service
branches of previously deployed OEF (Operation Enduring Freedom) and
OIF (Operation Iraqi Freedom) troops.
– Office of Public Health and Environmental Hazards is working with DMDC
to improve the accuracy and completeness of the roster and the variables
provided.

Current DoD Roster of
Recent Veterans
• Latest update of roster
– Provided to Department of Veterans Affairs (VA) Environmental
Epidemiology Service on October 12, 2009
• Qualifications of DoD’s OEF/OIF deployment roster
– Contains list of Veterans who have left active duty and does not include
currently serving active duty personnel
– Does not distinguish OEF from OIF Veterans
– Roster only includes separated OEF/OIF Veterans with out-of-theater
dates through August 2009
– Beginning with the 3rd Quarter FY 2009 report, Veterans who received
health care but subsequently died in-theater are being included in the
quarterly analysis. Because this is a cumulative report going back to
2002, and due to the duration of OEF/OIF and repeated deployments, a
certain number of these Veterans may have accessed VA health care
services
– The number of individuals who died in-theater through 4th Quarter FY
2009 is 4,898

This roster is used to check the VA’s electronic inpatient and outpatient
health records, in which the standard ICD-9 diagnostic codes are used to
classify health problems, to determine which OEF/OIF Veterans accessed VA
health care as of September 30, 2009.
The data available for this analysis are mainly administrative data obtained
from Veterans’ VA medical records and are not based on a review of each
patient record or a confirmation of each diagnosis. However, every clinical
evaluation is captured in VA’s computerized patient record. The data used in
this analysis are appropriate for health care planning purposes because the
ICD-9 administrative data accurately reflect the need for health care
resources.
These administrative data have to be interpreted with caution because they
only apply to those OEF/OIF Veterans who have accessed VA health
care. These data do not represent all 1,094,502 OEF/OIF Veterans who
have become eligible for VA health care since FY 2002 or the approximately
2.04 million troops who have served in the two theaters of operation since the
beginning of the conflicts in Iraq and Afghanistan1.

Because VA health data are not representative of the Veterans who have not
accessed VA health care, formal epidemiological studies are required to
answer specific questions about the overall health of OEF/OIF Veterans.
Analyses based on this updated roster are not directly comparable to prior
reports because the denominator (number of OEF/OIF Veterans eligible for
VA health care) and numerator (number of Veterans enrolling for VA health
care) change with each update.
•
This report presents data from VA’s health care facilities and does not
include Vet Center data or DoD health care data.
•
The following health care data are “cumulative totals” since FY 2002 and
do not represent data from any single year.
•
The numbers provided in this report should not be added together or
subtracted to provide new data without checking on the accuracy of these
statistical manipulations with VA’s Office of Public Health and Environmental
Hazards.

Diagnostic Data
•
•
•
•
Veterans of recent military conflicts have presented to VA with a wide range of
medical and psychological conditions.
Diagnoses have encompassed more than 8,000 discrete ICD-9 diagnostic
codes.
The three most common possible diagnoses of Veterans were
musculoskeletal ailments (principally joint and back disorders), mental
disorders, and “Symptoms, Signs and Ill-Defined Conditions.”
As in other outpatient populations, the ICD-9 diagnostic category, “Symptoms,
Signs and Ill-Defined Conditions,” was commonly reported. It is important to
understand that this is not a diagnosis of a mystery syndrome or unusual
illness. This ICD-9 code includes symptoms and clinical findings that are not
coded elsewhere in the ICD-9. It is a diverse, catch-all category that is
commonly used for the diagnosis of outpatient populations. It encompasses
more than 160 sub-categories and primarily consists of common symptoms
that do not have an immediately obvious cause during a clinic visit or isolated
laboratory test abnormalities that do not point to a particular disease process
and may be transient.

1 These
are cumulative data since FY 2002. ICD diagnoses used in these analyses are obtained from computerized administrative data. Although diagnoses
are made by trained health care providers, up to one-third of coded diagnoses may not be confirmed when initially coded because the diagnosis is
provisional, pending further evaluation.
2 A total of 243,685 unique patients received a diagnosis of a possible mental disorder. A Veteran may have more than one mental disorder diagnosis and
each diagnosis is entered separately in this table; therefore, the total number above will be higher than 243,685.
3 This row of data does not include information on PTSD from VA’s Vet Centers or data from Veterans not enrolled for VA health care. Also, this row does not
include Veterans who did not receive a diagnosis of PTSD (ICD 309.81) but had a diagnosis of adjustment reaction (ICD-9 309).
4 This category currently excludes 67,172 Veterans who have a diagnosis of tobacco use disorder (ICD-9CM 305.1) and no other ICD-9CM 305 diagnoses.

Summary
•
•
•
Recent OEF and OIF Veterans are presenting to VA with
a wide range of possible medical and psychological
conditions.
Recommendations cannot be provided for particular
testing or evaluation – Veterans should be assessed
individually to identify all outstanding health problems.
46.4% of separated OEF/OIF Veterans have sought VA
health care since 2002 compared to 45.8% in the last
quarterly report three months ago. As in other cohorts of
military Veterans, the percentage of OEF/OIF Veterans
receiving health care from the VA and the percentage with
any type of diagnosis will tend to increase over time as
these Veterans increasingly continue to enroll for VA
health care and to develop new health problems.
Cumulative from 1st Quarter FY 2002 through
4th Quarter FY 2009

Summary (2)
•
•
Because the 508,152 OEF and OIF Veterans who have
accessed VA health care were not randomly selected and
represent just 28% of the approximately 2.04 million
OEF/OIF Veterans1, they do not constitute a
representative sample of all OEF/OIF Veterans.
Reported diagnostic data are only applicable to the
508,152 VA patients – a population actively seeking
health care -- and not to all OEF/OIF Veterans.
For example, the fact that about 48% of VA patient encounters were coded
as related to a possible mental disorder does not indicate that
approximately half of all recent Veterans are suffering from a mental health
problem. Only well-designed epidemiological studies can evaluate the
overall health of OEF/OIF Veterans.

Summary (3)
•
•
•
Rates of VA health care utilization by recent OEF/OIF Veterans
may be influenced by combat Veterans’ enhanced access to VA
health care enrollment (in January 2008, this authority was
extended from 2 years to 5 years post discharge) and exemption
from copay charges for any health problem possibly related to their
military service.
Also, an extensive outreach effort has been developed by VA to
inform these Veterans of their benefits, including the mailing of a
personal letter from the VA Secretary to Veterans identified by DoD
when they separate from active duty and become eligible for VA
benefits.
When a combat Veteran's enhanced health care eligibility expires,
the Veteran will be moved to their appropriate priority group and
charged all co-payments as applicable. If their financial
circumstances place them in Priority Group 8, their enrollment in
VA will be continued, regardless of the date of their original VA
application.
Cumulative from 1st Quarter FY 2002 through
4th Quarter FY 2009

Follow-Up
• VA will continue to monitor the health
care utilization of recent OEF/OIF
Veterans using updated deployment
rosters provided by DoD to ensure that
VA tailors its health care and disability
programs to meet the needs of this
newest generation of Veterans.
