Billing & Reimbursement

Phone (805) 485-8709 option 6;   Fax (805) 981-8645

We are participating providers for Medicare and most major insurances.  Please check  with your insurer to find out if we are preferred providers.  This usually determines your out-of pocket cost.   We will submit claims to your carrier in your behalf.  We bill insurance companies, including Medicare as PMK Medical Group, Inc.

Please inform our office if pre-certification is necessary with your plan. Some insurance companies require you to use a specific laboratory, imaging center or need pre-certification for office visits, hospital admissions and treatment.  It is your responsibility to obtain the initial referral on your first visit.

If you have any questions about your statement regarding professional services provided by your physician in the office or hospital,

you may contact our Reimbursement Specialist directly at (805) 485-8709.

If your primary insurance is:

-Medicare or Gold Coast Medi-Cal, Tri-Care, HMO call Debra at extension 116

-All others, call Jennifer at extension 142
