MAs may not work for inpatient care in licensed general acute care hospitals. They are regulated by the Medical Board of California. They must be over 18 years old, trained and supervised. They may be certified. Unless prohibited by law, California MAs can perform basic administrative, clerical and technical supportive services when conditions regarding supervision, training, specific authorization, and records are met.
