L.A. County Health Services has defined 8 or so "regions" for their clinics.
The state has for many years had Health Service Areas (HSAs) and within them,
Health Facilities Planning Areas (HFPAs). The L.A. HFPAs are as follows:
 
'0901'='0901 - Lancaster'
'0903'='0903 - San Fernando'
'0905'='0905 - Van Nuys'
'0907'='0907 - Burbank'
'0909'='0909 - Glendale'
'0911'='0911 - Pasadena'
'0913'='0913 - West San Gabriel'
'0915'='0915 - East San Gabriel'
'0917'='0917 - Pomona'
'0919'='0919 - Whittier'
'0921'='0921 - Downey-Norwalk'
'0923'='0923 - Lynwood'
'0925'='0925 - Los Angeles'
'0927'='0927 - Santa Monica'
'0929'='0929 - Inglewood'
'0931'='0931 - Torrance'
'0933'='0933 - Long Beach'
'0935'='0935 - Watts'
'0937'='0937 - La Canada'
 
the only problem is that these were originally defined based on zip codes and
the defn's haven't been updated for new zip codes in many years. FOr major
urban areas that's not so much a problem, but for newer subs, etc. (e.g. San
Diego) where there are many new zips, you'd have to manually assign them.
 
Hope this helps,
