Managed Care Models

Managed care plans are a type of health insurance. They have contracts with healthcare providers and medical facilities to provide care for members at reduced costs. These providers typically make up the plan’s network. Your text lays out six models of managed care. We will further study four of the plans. Below, you will find several links you will need in order to complete this assignment:

Correlate four of the six managed care models with their characteristics.

Include the following in your assignment:

· Describe the financial differences between the models.

· Which model provides the most flexibility for patients to select their providers?

· Which model would you select and why? Managed Care Models

What are four of the six managed care models and their characteristics?,
What are the financial differences between these models?,
Which model provides the most flexibility for patients to select providers?,
Which model would you personally select and why?,
How do these models impact cost and access to care?

Comprehensive Response

Managed care plans are designed to reduce healthcare costs while ensuring patients have access to necessary services. Four commonly used models include:

Health Maintenance Organization (HMO): Members must use in-network providers, and referrals are required for specialists. Costs are usually lower, but flexibility is limited.
Preferred Provider Organization (PPO): Patients have access to both in-network and out-of-network providers, though out-of-network care costs more. Referrals are generally not required.
Point of Service (POS): A hybrid of HMO and PPO, requiring a primary care provider (PCP) and referrals, but allowing limited out-of-network care at higher costs.
Exclusive Provider Organization (EPO): Similar to an HMO, but no referrals are needed for specialists. Care must be received within the network unless in an emergency.

Financial differences among these models are significant. HMOs and EPOs typically have lower premiums and out-of-pocket costs but restrict provider choice. PPOs have higher premiums but greater flexibility. POS plans balance cost and access, often falling in between.

The PPO model provides the most flexibility for patients since it allows both in-network and out-of-network provider choices without referrals.

Personally, I would select a PPO plan because of the balance it offers between access and convenience. The ability to see specialists without referrals and choose providers outside the network provides peace of mind, even though the premiums may be higher.

Overall, these models illustrate the trade-offs between cost savings and provider choice, highlighting how managed care influences both affordability and patient autonomy.Managed Care Models

Billing Work Settings

By Academic Wizard Blog

Billing Work Settings

Our personality type may guide us toward our preferred profession. If it were even possible to categorize ourselves as either introverted or extroverted this classification could help direct us. Introverts (or those of us with introverted tendencies) tend to recharge by spending time alone. We lose energy from being around people for long periods, particularly in large crowds. Extroverts, on the other hand, gain energy from other people.

In this week’s supplemental reading assignment #1 the differences between working as a medical coder and/or billing specialist in the hospital environment versus a physician’s office are explored.

Explore the role of a medical coder and/or billing specialist in different work environments.

Include the following aspects in the discussion:

· Discuss how you view the differences between a hospital billing position and that of a physician’s office.

· Do you see yourself as an introvert or an extrovert? Billing Work Settings

· Based on your personality, would you prefer a hospital setting or a physician’s office setting?

· Are there other factors that would affect your selection of setting (besides personality or Introvert vs. Extrovert)?

Billing Work Settings

What are the differences between hospital billing and physician’s office billing?,
Do you see yourself as an introvert or an extrovert?,
Based on your personality which setting would you prefer?,
What other factors affect the choice of setting besides personality?,
How do these differences shape your perspective on career direction?

Comprehensive Response

The role of a medical coder or billing specialist can vary significantly depending on the work environment. Hospital billing tends to be more complex, involving a broader range of services, multiple departments, and inpatient as well as outpatient procedures. Hospital coders often handle higher volumes of claims with more detailed documentation requirements. In contrast, physician’s office billing usually involves a smaller scope, focusing on outpatient or specialty services, with closer interaction between staff and providers. This environment may allow for more consistency in coding and billing tasks, though it may also mean less variety compared to a hospital.

I identify more with an introverted personality, as I gain energy from working independently and prefer structured tasks. Based on this, I would lean toward a physician’s office setting, where the smaller scale may offer a more predictable workflow and less overwhelming interpersonal demand.

However, other factors also influence this choice. For example, career growth and exposure to a wide range of coding cases may be greater in a hospital setting. Salary differences, opportunities for specialization, and access to professional development can also shape the decision. Additionally, lifestyle considerations such as schedule flexibility, commute time, and work-life balance play important roles.

Ultimately, while personality provides some guidance, I believe the choice between hospital and physician’s office billing should balance both personal preferences and professional opportunities for growth.

Medicare for All

By Academic Wizard Blog

Medicare for All

Last week we talked about healthcare reforms being partially motivated by the cost of health care. This week we are focusing on some of the managed care options from which patients may choose to help mitigate some of the costs of health care. These managed care options do help lower the cost for most insured patients. But, is it enough, and what about our patients who do not have health insurance? There are increased discussions among politicians and the public about taking a bigger step toward fixing our healthcare system; Medicare for All. After you have viewed this week’s 2 videos and read the supplemental reading #2 about hospital billing:

Express your views about the possible need for “Medicare for All”.

Include the following aspects in the discussion:

· What Medicare for All, as presented by Bernie Sanders, would look like? (Sen. Sanders is being picked solely for simplifying the assignment, not because he is the best or even the best candidate.)

· Discuss the pros and cons of Medicare for All. Medicare for All

· What is your opinion about the viability of a single-payer option?

What would Medicare for All as presented by Bernie Sanders look like?,
What are the pros of Medicare for All?,
What are the cons of Medicare for All?,
What is your opinion about the viability of a single-payer option?,
Is Medicare for All enough to address healthcare costs and access?

Comprehensive Response

Medicare for All, as proposed by Senator Bernie Sanders, envisions a single-payer healthcare system in which the federal government provides comprehensive health insurance to all residents. This plan would eliminate private health insurance for essential medical services and guarantee universal coverage, meaning every individual would have access to hospital care, physician visits, prescription drugs, and preventive services without co-pays or deductibles.

The pros of Medicare for All include universal access to healthcare, significant reductions in administrative costs, and elimination of disparities in access between insured and uninsured populations. Patients would not need to worry about losing insurance through unemployment or job changes, and preventive care could improve overall public health.

The cons include the massive cost of transitioning to such a system, the potential for increased taxes, and the challenge of restructuring an industry deeply reliant on private insurance. Critics also warn of possible delays in accessing care due to higher demand and limited resources.

Regarding the viability of a single-payer option, I believe it is conceptually strong in terms of equity and long-term cost savings, but politically and structurally it faces major barriers. The U.S. healthcare system is complex, and powerful stakeholders such as private insurers and pharmaceutical companies strongly oppose such reform.

Ultimately, Medicare for All could address many gaps in coverage, especially for uninsured populations, but implementing it would require significant political will and careful planning to ensure sustainability and efficiency. Medicare for All

Certification Pathways

What progress have you made in exploring billing and coding certification exams?,
What factors are you considering such as industry recognition specialization and career alignment?,
What research findings support your choice of certification exam?,
Why does a specific certification exam seem most suitable for you?,
What valuable insights or advice have you gathered from various sources?

Comprehensive Response

In exploring billing and coding certification exams, I have focused on understanding which credentials hold the greatest weight in the healthcare industry. The two most recognized certifications are the Certified Professional Coder (CPC) offered by AAPC and the Certified Coding Specialist (CCS) offered by AHIMA. Both are widely respected, but they serve different career pathways.

The main factors I considered were industry recognition, specialization opportunities, and career alignment. The CPC is strongly associated with physician-based and outpatient settings, while the CCS is considered the gold standard for hospital and inpatient coding. These differences matter because the type of certification influences not only the work environment but also long-term professional opportunities. Certification Pathways

Research shows that employers often prefer CCS-certified coders for hospital systems because of the exam’s emphasis on complex coding and medical record analysis. The CPC, however, is praised for its focus on outpatient care and is ideal for private practices and clinics. Based on these findings, I see the CCS as particularly appealing since it provides flexibility and credibility across diverse healthcare environments, especially for those who may want to advance into leadership or specialized coding roles.

From discussions in professional forums and advice shared by coding professionals, a common recommendation is to choose the certification that opens the broadest range of opportunities initially, while later pursuing niche certifications. This strategy supports both employability and long-term growth. Certification Pathways

How do you feel about being a practice scholar?,
How do competencies and sub-competencies affect your perspective on graduate education and professional development?,
What are your professional priorities for continuing growth?,
What reflections do you have on this week’s material?

Comprehensive Response

1. Who I Am Becoming a Practice Scholar

I am currently a Psychiatric Mental Health Nurse Practitioner (PMHNP) specializing in the care of adolescents and children. I have been practicing as a PMHNP for about one year, but my professional journey in mental health spans over a decade. My experiences across inpatient, outpatient, and community-based mental health services have given me a deep appreciation for the complexity of psychiatric care. My long-term goal is to open my own practice to provide accessible, holistic mental health services tailored to children, adolescents, and families.

2. Feelings About Being a Practice Scholar

Being a practice scholar is both motivating and empowering. As a DNP student, I see practice scholarship as an opportunity to bridge the gap between research and practice, transforming evidence into meaningful, real-world change. I feel a strong sense of responsibility to contribute to advancing mental health care through innovation, leadership, and advocacy. The role of a practice scholar positions me not only as a provider but also as a leader in shaping systems that improve access and quality of care.

3. Competencies, Graduate Education, and Professional Development

The DNP competencies and sub-competencies outlined by the American Association of Colleges of Nursing (AACN) provide a framework for my educational and professional journey. They emphasize systems-based leadership, evidence-based practice, interprofessional collaboration, health equity, and quality improvement. These competencies shape my perspective by reinforcing that graduate education is not just about advanced clinical skills but also about developing the ability to lead, advocate, and innovate in healthcare. For my continuing professional development, this means prioritizing skills in quality improvement, policy advocacy, and culturally responsive care—all of which are essential for achieving my goal of running a successful, patient-centered practice.

4. Professional Priorities for Continuing Growth

As I advance in the DNP program, my priorities include expanding my leadership capacity, engaging in research translation, and developing entrepreneurial skills for private practice. I also want to strengthen my expertise in addressing health disparities, particularly for children and adolescents who often face systemic barriers to accessing mental health care. Building competency in interprofessional collaboration is another priority, as effective partnerships with schools, community agencies, and families are vital in child and adolescent psychiatry.

5. Reflections on This Week’s Material

This week’s material has reinforced the idea that the DNP-prepared nurse is uniquely positioned to serve as both a clinician and a social change agent. I was particularly struck by the emphasis on systems thinking—how small, evidence-based changes in practice can ripple outward to improve outcomes on a larger scale. It made me reflect on how my own role as a PMHNP can extend beyond one-on-one care to shaping programs and policies that impact entire communities. This perspective strengthens my motivation to pursue my DNP with a focus on blending clinical expertise, scholarship, and leadership in ways that directly support my long-term goals.

How is the DNP role linked to social change and how can you advocate for it?

Comprehensive Response

1. Philosophy of Nursing Practice

My philosophy of nursing practice is rooted in a holistic, patient-centered approach that values compassion, evidence-based care, and advocacy. I view nursing not only as a profession of skill and knowledge but also as a moral commitment to promote health, alleviate suffering, and empower individuals and communities to achieve their highest potential for well-being. Nursing extends beyond physical care; it also addresses psychological, cultural, and social dimensions of health.

2. Nursing Experience and Expertise

My nursing experience has been shaped by providing care across diverse populations and clinical settings. Exposure to acute care, community health, and interdisciplinary collaboration has reinforced the importance of adaptability and cultural competence. Over the years, I have developed expertise in patient education, leadership, and evidence-based decision-making, which support my philosophy that nurses are both caregivers and change agents.

3. Underlying Tenets of My Philosophy

Several core tenets guide my philosophy of nursing:

Holism: Recognizing patients as whole beings whose health is influenced by biological, psychological, social, and spiritual factors.
Advocacy: Ensuring that vulnerable populations have access to equitable healthcare resources.
Lifelong Learning: Embracing continuous professional development to provide high-quality, evidence-based care.
Diversity and Inclusion: Respecting cultural values, traditions, and beliefs to provide care that honors individuality.

These tenets reflect nursing’s ethical foundation and its alignment with professional standards of practice.

4. Goals for Expanding Experience and Practice as a DNP Nursing Philosophy Statement

As a Doctor of Nursing Practice (DNP) student, my goal is to strengthen my leadership in addressing diversity, global health, and interprofessional collaboration. Embracing diversity means fostering inclusivity in healthcare delivery to reduce disparities. Global health engagement includes understanding social determinants of health and leveraging research to address transnational challenges. Collaboration emphasizes working across disciplines to improve health outcomes and system efficiency. Through these efforts, I aspire to advance nursing practice from the individual level to broader systems of care.

5. The DNP as a Social Change Agent

The DNP-prepared nurse holds a unique role in leading positive social change through policy advocacy, community engagement, and health system innovation. By combining clinical expertise with systems thinking, DNPs can identify inequities and implement sustainable interventions. For example, advocating for culturally competent policies within healthcare organizations ensures equity in patient care and strengthens trust between providers and communities.

Recommendation: One way to advocate for positive social change as a Walden DNP is by leading initiatives to address healthcare disparities in underserved populations. For instance, developing community-based health promotion programs for marginalized groups can reduce preventable illnesses and hospital readmissions. Evidence-based advocacy, combined with community partnerships, embodies the DNP’s role as a transformational leader.

✅ Comprehensive General Answers

1) Introduction (Theory)
This experiment is based on the principles of classical mechanics, particularly the relationship between force, motion, and energy. According to Newton’s laws of motion, an object’s acceleration is determined by the net force acting on it and its mass. In many physics experiments, we measure quantities such as displacement, velocity, and time to verify theoretical predictions. A common formula applied is $F = ma$ , where $F$ is force, $m$ is mass, and $a$ is acceleration. Another useful relationship is the kinematic equation:

$\tfrac{1}{2}at^2$

where $s$ is displacement, $u$ is initial velocity, $a$ is acceleration, and $t$ is time. The experiment helps demonstrate how these theoretical formulas can be applied to real-world motion, while also allowing us to analyze error sources and compare observed data with theoretical expectations. Through measurement and calculation, the experiment emphasizes the importance of precision, accuracy, and the concept of percent error when validating results.

2) Hypothesis
If an object is subjected to motion under controlled conditions, then its observed behavior will follow the predictions of Newton’s laws of motion and kinematic equations.

3) Analysis (General Example)

Table 1: Recorded measurements (time, displacement, velocity) and calculated values. Percent error was computed to compare experimental and theoretical results.
Table 2: Repeated trials to improve accuracy and check consistency. Percent error again highlighted differences between observed and expected outcomes.
Chart/Plot: A graph of displacement vs. time showed a parabolic trend, confirming constant acceleration. A velocity vs. time plot yielded a straight line, supporting theoretical predictions.

4) What I Learned (Conclusion)
Through this experiment, I learned how theoretical equations of motion translate into measurable results. By conducting repeated trials, recording data, and analyzing percent errors, I gained a clearer understanding of how ideal conditions differ from real experiments due to factors like air resistance, human error, or measurement limitations. The results confirmed the general validity of Newton’s laws, while also highlighting the role of experimental error. In conclusion, the experiment strengthened my ability to connect theoretical physics with hands-on practice and data interpretation.

5) Results vs. Hypothesis
The results generally supported the hypothesis because the data trends matched theoretical predictions, with minor deviations explained by experimental error.

Nuclear Energy & Light

By Academic Wizard Blog

Nuclear Energy & Light

Scientists such as Heinrich Hertz, Philipp Lenard, Max Planck, and Albert Einstein made scientific contributions that ultimately demonstrated that light is electromagnetic radiation, and that it has a “dual nature.” Some electromagnetic phenomena are best explained with a particle model, and some with a wave model. In a sense, “wave” and “particle” are just easy mental models for light. We employ them because we are used to seeing waves and particles—such as those in water waves and baseballs—in our daily lives. Electromagnetic radiation is a basic concept in physics, but it doesn’t fit completely into one of these neat little boxes.

Research and discuss at least one modern technology that employs electromagnetic radiation and that can be explained by the wave model, the particle model, or a combination of the two. Some possible technologies include solar panels, burglar alarms, cameras, and cell phones.

Describe the components of a speaker and explain how it produces sound. In particular, explain how the force on a current-carrying wire in a magnetic field is used to make a speaker operate.

Electromagnetism & Aurora

Throughout this lesson, you learned about the lives and contributions of key scientists in this area of physics. Create a timeline that ties them all together. The timeline does not need to be highly detailed, but it should do the following:

Include at least the four major scientists covered in this unit: Oersted, Ampère, Faraday, and Tesla.
Include key contributions of each scientist and provide a year, if possible, for those contributions.
Note any relationships among these and other scientists, especially if one developed something based on the work of another.
Arrange the scientists chronologically by their first key contribution, not by their birth date.

What causes the aurora borealis and when/where is it best observed?,
What happens when a magnet is moved in different ways through/near a coil?,
What causes electricity to flow in a coil?,
How does a loudspeaker work using electromagnetism?,
What is the timeline of Oersted Ampère Faraday and Tesla’s contributions?
