Unit 6 Prospective Payment Worksheet
[Instructor Name]
[Date]
The hospital, the stay, the procedure and every input are composite; the payment formulas and the sources cited are real.
Inputs
All inputs are composite, chosen to resemble a recent federal year. Inpatient standardized amount: $6,600. Labor-related share: 67.6 percent. Area wage index: 1.0500. Group relative weight: 1.2000. Outpatient conversion factor: $89.17. Outpatient labor-related share: 60 percent. Payment classification weight: 3.4000.
Panel 1: Inpatient Stay
Formula in words: the hospital's base rate equals the labor-related portion of the standardized amount multiplied by the wage index, plus the nonlabor portion unadjusted. The stay's payment is then the base rate times the weight of its group, before any additional adjustments (42 C.F.R. § 412.64, 2024).
1. Labor portion: $6,600 times 0.676 equals $4,461.60.
2. Wage-adjusted labor portion: $4,461.60 times 1.0500 equals $4,684.68.
3. Nonlabor portion: $6,600 times 0.324 equals $2,138.40.
4. Hospital base rate: $4,684.68 plus $2,138.40 equals $6,823.08.
5. Payment: $6,823.08 times 1.2000 equals $8,187.70.
The wage index applies only to the labor portion because labor costs vary by area while supplies and equipment cost roughly the same everywhere. So an identical stay pays more where nurses and technicians earn more, and less where they earn less. The group weight reflects the average resources used by stays in that group relative to the average stay, and the hospital does not set it. Adjustments not included here would raise or lower the payment in practice: teaching and disproportionate share adjustments, outlier payments for unusually costly cases, and the transfer rule for patients discharged early to post-acute care (42 C.F.R. § 412.4, 2024). Each is a separate calculation added after the base payment. The hospital controls neither the weight nor the base rate. It controls only whether the diagnosis codes place the stay in the right group.
Panel 2: Outpatient Procedure
Formula in words: the payment equals the conversion factor, with its labor-related portion adjusted by the wage index, multiplied by the classification's relative weight (42 C.F.R. § 419.31, 2024).
1. Labor portion of the conversion factor: $89.17 times 0.60 equals $53.50.
2. Wage-adjusted labor portion: $53.50 times 1.0500 equals $56.18.
3. Nonlabor portion: $89.17 times 0.40 equals $35.67.
4. Adjusted conversion factor: $56.18 plus $35.67 equals $91.85.
5. Payment: $91.85 times 3.4000 equals $312.27.
The outpatient system groups clinically similar procedures with similar costs into the same classification, so different procedure codes can pay the same amount. Packaging rules fold many supplies and minor services into the main procedure's payment, which is why a single classification payment often covers several lines on the claim.
Where the Inputs Come From Each Year
None of the inputs on this worksheet is fixed for long. The federal government publishes the inpatient standardized amount, the labor-related share, the wage indexes and the group weights in its annual payment rule, effective each October, and the outpatient conversion factor and classification weights in a separate rule effective each January. Wage indexes are built from hospitals' own reported wage data, with a lag of several years, so a hospital's area index reflects the local labor market as it was rather than as it is. Group weights are recalibrated each year from claims and cost data, which means the same stay can pay a different amount from one year to the next with no change in the hospital's practice. A worksheet like this one should therefore always name the fiscal or calendar year its inputs come from, and a hospital's finance office reruns its projections every time a new rule is published.
Checking the Arithmetic
Two quick checks catch most errors. In panel 1, the hospital base rate should be slightly above the standardized amount when the wage index is above 1.0, and slightly below it when the index is below 1.0, because only about two-thirds of the rate moves. In panel 2, the adjusted conversion factor should move by about 60 percent of the wage index's distance from 1.0. A result that moves by the full wage index has applied it to the whole rate.
What the Two Panels Have in Common
Both systems start from a weight assigned by the federal government, multiply it by a rate adjusted for local wages, and pay the same amount for every case in the group regardless of the hospital's actual cost for that patient. Both therefore reward a hospital that delivers the care for less than the payment and penalize one that spends more. The difference is the unit: a whole inpatient stay in one, a procedure or visit in the other.
Why This Matters to Coders
In panel 1, one documented secondary condition of the right kind can shift a stay to a sibling group carrying a heavier weight. In panel 2, the procedure code determines the classification. Coding errors in either direction change payment, and payers and auditors look for both. Getting the codes right is the one input in these formulas that the hospital's own staff control.

What the HI215 Unit 6 assignment asks for
Unit 6 generally provides weights, rates and a wage index and asks you to calculate prospective payments with an explanation. Write each formula in words before substituting numbers, so the method can be checked apart from the arithmetic. Apply the wage index only to the labor-related share. Show each intermediate result, round consistently and label every input as given or composite. After each panel, explain what the result means and which adjustments, such as outliers or transfers, would change it in practice. Note where the inputs come from and how often they change. Connect the formulas to coding, since the hospital's own staff control which group or classification applies. Many prompts include one inpatient and one outpatient calculation.
Inside the HI215 Unit 6 example
The worksheet lists all inputs at the top as composite. Panel 1 states the inpatient formula in words, then five numbered steps from labor portion to payment, followed by paragraphs on the wage index, the group weight and the adjustments left out, including the transfer rule. A highlighted line notes what the hospital does not control. Panel 2 does the same for the outpatient conversion factor and classification weight, with a paragraph on packaging. A margin note explains the purpose of the explanatory paragraphs. Sections on yearly inputs, arithmetic checks, the two systems' common logic and what coders control close the worksheet. Every result is shown to the cent, so a grader can follow the arithmetic line by line.
HI215 Unit 6 rubric: what earns full points
Prospective payment worksheets are usually graded on correct formulas and accurate arithmetic. Points go to splitting the rate correctly, applying the wage index only to the labor share and multiplying by the right weight. Credit rises for showing every intermediate step and for explanations that interpret the results. Instructors value awareness of adjustments not calculated and of how inputs change from year to year. Linking the result to coding accuracy demonstrates applied understanding. Clear layout and citations to the payment regulations complete the rubric. Applying the wage index to the whole rate, or skipping steps so the arithmetic cannot be checked, typically loses the most points.
Common HI215 Unit 6 mistakes, and how to avoid them
The most common error is multiplying the entire base rate by the wage index. Only the labor portion is adjusted. Another is mixing inpatient and outpatient shares, which differ. Students sometimes round early and carry the error through. Keep two decimal places until the final result. Do not forget to say what adjustments you did not include. Use a quick check: a wage index above one should raise the base rate by less than the index itself. Write the formula in words first. If your prompt gives different inputs, send them and we can set out both panels with every step shown. Label each input with the year it represents.

HI215 Unit 6 questions, answered
Why is only part of the base rate adjusted for wages?
Because only part of a hospital's cost is labor, and labor is what varies by area. The standardized amount is divided into a labor-related share, adjusted by the local wage index, and a nonlabor share paid at the national figure. The worksheet shows both portions separately so a reader can see which part moved and by how much.
Does the worksheet need to handle outliers or transfers?
Only if the scenario raises them. The example names both exceptions in its interpretation paragraph without calculating either, because its supplied case is an ordinary stay. Where your worksheet gives a cost figure above a threshold, or a discharge to another facility before the expected length of stay, those calculations become part of the answer and follow the same shown-work layout.

Why is only part of the base rate adjusted for wages?
Because only part of a hospital's cost is labor, which varies by area, while supplies and equipment cost roughly the same everywhere.
Does the worksheet need to calculate outliers or transfers?
Only if the scenario raises them. Naming them as adjustments that would change the payment, as this worksheet does, shows they were considered.
