Doctors Billing Services

Doctors Billing Service is a San Francisco-based medical billing company that manages the full revenue cycle for physician practices, specialists, and multi-specialty clinics across the Bay Area and California. Founded and led by Caroline Kats, the firm brings over 20 years of hands-on experience to every client engagement, helping healthcare providers collect what they are owed while cutting the administrative burden on their in-house staff. The company covers the complete billing workflow from intake to payment. Daily claims submission keeps the revenue cycle active, while dedicated insurance follow-up tracks claim status and catches rejections before they stall cash flow. When denials occur, the team handles corrections, resubmissions, and direct payer communication to recover unpaid balances. Additional services include paper and electronic claims processing, patient statements, payment posting, accounts receivable management, aging reports, and detailed financial reporting. Practices receive a clear picture of their billing performance without having to manage it themselves. Doctors Billing Service works with a broad range of healthcare providers, including solo practitioners, multi-specialty groups, Medicare patients, workers' compensation cases, and surgical practices. The firm has particular depth in podiatric billing, a specialty that demands precision and familiarity with payer-specific requirements. By outsourcing billing operations to an experienced back-office team, practices eliminate the cost of hiring, training, and retaining in-house billing staff, along with the overhead of dedicated software, payroll, and benefits. Located in San Francisco, the firm serves practices throughout the Bay Area, including Richmond District, Pacific Heights, the Sunset District, Daly City, South San Francisco, Oakland, Berkeley, and Marin County, as well as practices statewide across California. All work is conducted in full HIPAA compliance and in alignment with California law. Caroline Kats manages billing directly, giving clients access to a senior practitioner rather than a rotating pool of agents. Commission rates are below the national average, with no hidden fees. For any medical practice dealing with delayed reimbursements, mounting denials, or the ongoing cost of in-house billing operations, Doctors Billing Service offers a practical, proven outsourcing alternative.
