Why Payer Mix Changes the Meaning of Volume
The previous module found that Cedar Plains Regional Medical Center, the composite 180-bed hospital used in this course, saw roughly one in five of its hip and knee replacement cases move to an academic medical center and a physician-owned surgery center over five years. Volume alone does not tell the strategy committee how much that loss matters. A hospital earns very different amounts for the same procedure depending on who pays. Medicare and Medicaid set prices administratively, and commercial insurers negotiate them. A national analysis of claims from employer-sponsored plans found that private plans paid hospitals on average 247 percent of what Medicare would have paid for the same services in 2018, with wide variation across states and hospitals (Whaley et al., 2020).
That gap means a commercially insured patient can contribute several times the margin of a Medicare patient receiving the same care, and a Medicaid patient may contribute a negative margin. A service line losing commercial patients to a competitor loses far more than its volume suggests. Porter (2008) argues that strategy must begin with an understanding of the forces shaping competition in each business, including the bargaining power of buyers, and in health care the most powerful buyers are payers. Two service lines can lose the same number of patients and face completely different futures, because they lost different payers.
Orthopedics and Joint Replacement
Main competitors: the academic medical center, which employs the county's largest orthopedic group, and a physician-owned ambulatory surgery center. Share of county joint replacements: 64 percent five years ago, 44 percent last year. Payer mix at Cedar Plains: Medicare 58 percent, commercial 34 percent, Medicaid 6 percent, other 2 percent. Contribution margin last year: about $4.1 million, down from $6.3 million five years ago.
The payer mix explains why the margin fell faster than the volume. The surgery center attracts healthier, younger, commercially insured patients, whose cases carry the highest margins, while the academic center attracts complex cases. Cedar Plains is left with a rising share of Medicare patients, whose hospital payments were further reduced when knee and hip replacements became eligible for outpatient payment. Orthopedics remains the hospital's second most profitable service line, but it is losing its best-paying patients first.
Cardiology, General Surgery, Obstetrics and Behavioral Health
Cardiology: main competitor is the academic center's heart institute. Share of county cardiac admissions is stable at about 55 percent, because emergency cardiac care is local. Payer mix: Medicare 66 percent, commercial 25 percent, Medicaid 7 percent. Contribution margin about $7.2 million, the highest of the five. Threat level is low for emergency cases, but elective procedures such as catheter ablation are migrating to the academic center.
General surgery: competitors are the academic center and the surgery center for simple procedures. Share stable at about 60 percent. Payer mix: Medicare 41 percent, commercial 39 percent, Medicaid 16 percent. Margin about $3.0 million. Obstetrics: competitor is a smaller hospital 20 miles away. Share stable at 70 percent of county births. Payer mix: Medicaid 52 percent, commercial 45 percent. Margin about negative $1.1 million, typical of community obstetrics with high Medicaid volume. Behavioral health: no inpatient competitor in the county. Share near 90 percent of local admissions. Payer mix: Medicaid 48 percent, Medicare 27 percent, commercial 19 percent. Margin about negative $2.4 million.
The four lines face different fights. Cardiology is profitable and protected by the emergency nature of most of its work. General surgery is stable. Obstetrics and behavioral health lose money but are community services the hospital has committed to maintain, and their losses are funded by the profitable lines. The service lines that lose money are only sustainable as long as the lines that make money keep making it.
How the Surgery Center Competes
The surgery center deserves closer attention, because its competitive advantage is structural rather than a matter of service quality. Surgeons who own a share of an ambulatory surgery center earn a portion of its facility profits in addition to their professional fees, which gives them a financial reason to perform eligible cases there rather than at a hospital. Hollingsworth et al. (2010), studying Florida data for five common outpatient procedures, found that physician ownership of surgery centers was associated with higher surgical volume, and they raised concern about the conflict between owners' financial incentives and patients' clinical needs. Whatever the clinical merits of any individual decision, the pattern means that surgeon-owners have an incentive to bring their commercially insured, lower-risk patients to the center they own.
For Cedar Plains, this changes what competing with the surgery center means. The hospital cannot win those patients back by improving service at the hospital, because the surgeons' decision is shaped by ownership as well as convenience. The competitive responses available are to offer the surgeons an ownership opportunity of their own, to compete on price with payers who steer patients to the lowest-cost setting or to concentrate on the complex cases the surgery center cannot take. Each is a different strategy, and the next module will narrow them to the one the hospital can fund. A competitor whose advantage is ownership cannot be beaten on hospitality.
Ranking by Strategic Importance
Ranked by volume at risk, orthopedics and general surgery would sit near the top, and cardiology near the bottom. Ranked by margin at risk, the picture changes. Orthopedics has lost more than $2 million in annual contribution margin in five years, and the loss is accelerating because the remaining volume is increasingly Medicare. Cardiology's elective procedures represent a smaller but high-margin risk. General surgery is stable. Obstetrics and behavioral health are not at competitive risk but depend on the margin the other lines produce.
Combining the two views, orthopedics is the service line of greatest strategic importance. It is the one where competitors are actively taking share, where the most valuable payers are leaving first and where a continued decline would reduce the hospital's ability to fund the community services that lose money. Cardiology is second, because protecting elective procedures now is cheaper than recovering them later.
What the Analysis Leaves Open
Two limits should be kept in view. The contribution margins rely on the hospital's cost accounting system, which allocates overhead by formula and may overstate or understate the true cost of each line. And the payer mix figures describe the patients Cedar Plains kept, not the ones it lost; confirming that the surgery center took mainly commercial patients would require payer information from state outpatient surgery data, which the strategy office has requested. Neither limit is likely to change the ranking, but both would sharpen the size of the problem the next module will address when it narrows possible responses to one the hospital can fund.
Conclusion
Reading the competition and the payer mix behind each service line shows that Cedar Plains faces five different fights. Cardiology is profitable and largely protected; general surgery is stable; obstetrics and behavioral health lose money by design and depend on the others. Orthopedics is where the hospital is losing ground to two competitors at once and losing its best-paying patients first. That combination makes orthopedics the service line where the strategy must start.

How this HLTH 5613 Module 2 example is structured
HLTH 5613 Module 2 typically reads the competition and the payer mix behind each service line; your classroom's instructions decide how many service lines and which financial measures. This example explains why payer mix changes the meaning of volume, then takes each service line in turn with its main competitor, its share trend, its payer mix and its contribution margin. A comparison section ranks the lines by strategic importance using both competition and payer mix, which a volume-only view would get wrong. The conclusion identifies the service line that matters most for the strategy to come.
HLTH5613 Module 2 questions, answered
What does HLTH5613 Module 2 usually ask for?
HLTH5613 Module 2 typically asks students to analyze the competition and payer mix behind a healthcare organization's service lines. Many sections expect market share, competitors and financial contribution to be examined for each line. Your classroom's instructions decide how many service lines to include and which financial measures to use.
Why does payer mix matter in a competitive analysis?
Because hospitals are paid very different amounts for the same care depending on the payer. Commercial insurers often pay far more than Medicare, and Medicaid often pays less than cost. A competitor that takes mainly commercial patients can reduce a service line's margin much faster than its volume, which changes the strategic importance of the loss.
How do I rank service lines by strategic importance?
Look at both volume and margin at risk, the strength and direction of competition and the role each line plays in funding the organization's other services. A line losing high-margin patients to active competitors usually ranks higher than a larger line with stable share, even if the larger line has more patients.
