Explain how the market forces have influenced the need for integrated delivery systems

Scenario: A patient is confused about how to make payments for a recent visit to urgent care and hospital stay. Her insurance provider website allows her to use her HSA account to make a payment online. She uses her HSA debit card to make the payment, but her insurance provider sends her a check instead of sending it to the Teri-City Health Care Agency. After contacting her insurance help desk via the website, she is told to send the check to Ti-City Health Care agency herself. The patient asks the insurance provider help desk representative why they can’t just make the payments for her. She is told about the various payment types and payers in the healthcare industry and how the market influences the integrated delivery systems in the industry.
After reading the scenario, answer the following (75-100 words each answer) in a separate document:
1. Describe the payer systems mentioned in the case study.
2. Explain how the market forces have influenced the need for integrated delivery systems.
3. How might the insurance provider explain the payment system they utilize for their clients? Explain if this method is effective or not for their clients.
4. What might be the most significant legal and regulatory effect on managed care organizations?
