I suggest you start with the State Medical Board site: http://www.mbc.ca.gov/consumer/access_records.html
I also saw this from an insurance carrier's web site: For the most part, state and federal laws regarding mandatory record retention time frames apply to hospitals or similar facilities rather than to a physician’s clinic. The Medicare Conditions of Participation (COP) require hospitals to retain records for five years (six years for critical access hospitals), whereas OSHA requires an employer to retain medical records for 30 years for employees who have been exposed to toxic substances and harmful agents. HIPAA privacy regulations have a six-year retention requirement, which follows the federal statute for limitations for civil penalties
Hmmm, this is very odd, typically, the length of time physicians keep records depends on two factors, the statute of limitations (usually two or three years) and the type of payer involved.
I would suggest making a formal request in writing for your records; ask them for their policy.
