UPDATE: On October 7, 2015, CMS released a new Excel spreadsheet, now calculating the Oncotype DX price as $3416. (Here). CMS did so by adding the dozen Noridian states to the spreadsheet, so now, the median is $3416 whether calculated by "state" or by "MAC."
The CMS spreadsheet is here.
Row 16 is the Oncotype DX Breast test (HCPCS code 81519), and column C shows the National Limitation Amount to be $2900. (MAC price proposals ranged from $2,062.40 to $3416). If you look at the live spreadsheet, the $2900 is a calculated figure based on the median of each column of the table in Row 16. See figure:
The table lists all the zones of the historic Clinical Laboratory Fee Schedule - there is one for every state, and a few states have 2 (CA) or even 3 (NY). The Excel median function calculates the median of filled cells, and ignores empty cells. OK, so $2900 is the median of the columns of the table.
Why do I think this is wrong?
CMS is bound by its own regulations in conducting its calculation of the median. Based on regulations, CMS is supposed to calculate the median by "Carrier" i.e. by MAC. The regulation is plain and simple:
42 CFR 414.508(b)(2) states: "In the second year, the test code is paid at the national limitation amount, which is the median of the carrier-specific amounts."If CMS had wanted to state, the median is the median of each state, or the median of each CLFS fee zone, they could easily have said so. The plain language is, the median of the carrier specific amounts. Carriers are MACs. {For more detail citing October 1, 2015 CMS rulemaking, see here.}
So let's look closer at the data. Oncotype DX Breast was priced by 6 MACs: CGS (KY OH) $3416, First Coast (FL PR) $3416, WPS (Indiana, Michigan) $3416, and Palmetto (NC SC VA WV) $3416. Two other MACs priced it lower: Cahaba (AL GA TN) $2900, and NGS (NY zones 1-3, CT, ME, MA, NH, RI, VT), $2062. The median price of the 6 MACs is $3416. That is, not all MACs reported, but of the six "carriers" reporting, the median is $3416.
You can download the full spreadsheet at the link at the top of this blog; the prices reported for each state (zone) and each MAC are also shown below. While the median of the 21 zones is $2900, the median of the six MACs is $3416, which seems to be what the regulation clearly instructs. (Most sources say that when there is an even number of samples, calculate the median as the average of the two middle numbers).
If my reading is correct, as shown in these screenshots, it raises a question of whether CMS can accurately and rapidly calculate the correct weighted median for over a thousand laboratory tests from millions of data points - through in-house methods that won't be available to inspect on a public Excel file like this one.
Trivia Point: The Northeastern MAC, NGS, reported the same proposed prices for all its 7 states except Connecticut, which is left blank in the CMS spreadsheet. That is, it has 7 states but reported for 6.
Parallel: See also discussions of the recent Shands v Burwell case, casting doubt on the accuracy and transparency of internal CMS rules and calculations (here).
Addendum: On September 28, Genomic Health released a press release noting that the CMS pricing was flawed, because CMS did not account for the price paid by its own contractor, Noridian [Noridian's columns were left blank by CMS], and other reasons. Here.
