Step-by-step explanation:
A complete examination of an HMO's affairs is conducted at least every three to five years. Health Maintenance Organizations (HMOs) are regulated at both federal and state levels, with varying requirements for reviews and audits to ensure they comply with health management and financial standards. A full review typically includes evaluation of the HMO's financial soundness, adherence to contract provisions, quality of care, accessibility of services, and overall management practices. States may also conduct targeted examinations more frequently based on specific needs or issues that arise.
