Table 2.
Characteristics of Veterans of Operations Enduring Freedom/Iraqi Freedom/New Dawn (OEF/OIF/OND) according to “first indicator of homelessness” group during fiscal years 2001–2012; N = 30,866.
Note. All demographic variables differed significantly across 1st homelessness classification groups following chi-square tests, all p < .0001.
Table 3.
Frequency of first administrative indicator of homelessness and receipt of V60.0 and outpatient services in the 90 days immediately following the first administrative indicator among a cohort of OEF/OIF/OND Veterans during fiscal years 2001–2012.
Note. ICD-9 codes V60.0 (lack of housing), V60.1 (inadequate housing), V60.89 (other specified housing or economic circumstance), V60.9 (unspecified housing or economic circumstances) and clinic stop codes 522 or 530 (Department of Housing and Urban Development VA shared housing program [HUD-VASH]), 528 (telephone/homeless mentally ill [HMI]), 529 (health care for homeless Veterans); 590 (community outreach to homeless Veterans), or inpatient homeless stays (28, homeless compensated mental health residential and rehab treatment program [(MH RRTP CWT/TR, treatment specialty]; 37, domiciliary care for homeless Veterans [DCHV, treatment specialty]).

Note. Values represent N (%). χ2 test and p-value come from z-tests for independent proportions with a correction for continuity.

Fig 1.
Map of usage of various administrative indicators for the recognition of homelessness in VA medical facilities across the country (V60.0, V60.1, V60.89. V60.9 and non-ICD codes: clinic stop codes and inpatient treatment codes as described in the text).
The pie charts are derived from a normalized ratio: the frequency of the specific code given as a first indicator of homelessness (numerator) as a proportion of the total number of Veterans identified as homeless in the area (denominator). Two representative years are shown.

A stacked bar graph of the variability in usage of V60 and non-ICD codes to identify homelessness among Veterans across 4 VA regions in the US.
Region 1 includes the East Coast, Region 4 the West Coast. The time period studied is 2002–2012.
