According to one source, a functional structure organizes activities around the mission-critical activities or process of the organization (Ginter, Duncan, & Swayne, 2010). This is very fitting for a healthcare organization. We often group our departments by services. For example, we might have surgery, primary care, nutrition, housekeeping, and emergency room. Each one of these areas has a specific role in the delivery of healthcare. By grouping in this manner, it allows for better management of staff and utilization of resources.  This week's discussion question explores the various organization structures that would be appropriate for a healthcare organization.s

https://hwacer.com/Tutorial/hsa-525-week-1-discussion-board/

Strayer Transplant Center is part of the SEI Healthcare System. It is a for-profit organization. All of the procedures are performed at the system's flagship hospital. The organization currently performs more than 750 procedures a year. The center generates over 80 million in revenue each year. However, we have seen a slight decline over the last few years.

The current organizational structure is considered to be functional. Senior management has put forth a recommendation to change the structure to another type to stop the loss of revenue. The options being considered are: divisional, matrix, and flatarchy. You are a consultant that has been brought in to evaluate these options. You will prepare a memorandum that discusses the each option and includes your recommendation. In your memorandum, list the type of structure (include the current one) with a brief definition. Identify the pros and cons of each one. Then make a recommendation on which option the organization change to if any. Also, address how this change in structure would impact the strategic planning activities of the organization.

Obtaining reimbursement for services provided involves not only the clinical team but staff in the business office. These staff include billers and coders, who each have a specific role when it comes to receiving payment for services rendered. Medical billing clerks interpret medical codes and submit bills to insurance companies, patients, and other agencies for medical services. A medical coding specialist is part of the medical records billing department of a healthcare organization, such as a hospital or a clinic. The coding specialist classifies diagnoses and procedures to facilitate billing and reimbursement from Medicare or health insurance companies. It is very important that each one does their job correctly. The medical coding specialist will be the focus of this discussion question.

You have just been hired as the coding supervisor for Big Wheel General Hospital. You were warned before taking the job that there were some issues with the department. However, you decided you were up to the challenge. Your first task, and probably most important, is to review the noted areas of deficiencies and provide a memorandum to the HIMS Director, Betty Kline, on which are the top two issues to focus on first and strategies to correct the issues.

These are the issues you have identified:

Not coding at the highest level.
Bad documentation/Missing documentation.
Not having access to the provider.
Failing to use current/updated code sets.
Under and overcoding.
Unbundling.

HSA 525 Week 5 discussion Board

There are two extremes when it comes to the power of providers to set prices. The first one is the provider has no power and must accept the reimbursement rate set by others. The second one is the provider sets the price and the third-party payers must accept them. Neither sounds like a win-win for all parties involved. We will explore these strategies in this week’s discussion question.

In your memo, be sure to first provide a brief discussion of what it means to be price-setter or price-taker. List the pros and cons of each one. Be sure to comment on the strategies that would be used in both scenarios. Finally, end the memo with your recommendation.
