      Sam has been excellent for my podiatry practice. He responds quickly and follows through on any concerns. My reimbursement has gone up significantly since transitioning to Docs medical. They also provide credentialing services and have been very helpful

      Docs Medical Billing has been helping my practice since I started last year. They get things done on time. They help my front and back staff to check eligibility, they help me set up.portals for insurances, and do their diligence on claims. They also help me find a web designer.I highly recommend them 👌
