The first mandatory bundled-payment program from the Center for Medicaid and Medicare Services (CMS), known as the Comprehensive Care for Joint Replacement (CJR) model, was implemented with the goal of better supporting patients undergoing the most common inpatient surgeries billed to Medicare: hip and knee replacements. The CJR model is also one of many CMS innovations that incentivize higher quality of care and reduced provider spending.

According to Definitive Healthcare data, MS-DRG 470 (major joint replacement or reattachment of lower extremity without major complications or comorbidities) ranked as the fourth highest inpatient diagnosis in 2019 — with 1,234,651 total diagnoses.

How does the CJR model work?

A CJR ‘episode’ begins when a patient is admitted to a participating hospital and is ultimately discharged under either MS-DRG 469 (major joint replacement or reattachment of lower extremity with major complications or comorbidities) or MS-DRG 470 and ends 90 days post-discharge.

Annually, CJR participating hospitals receive unique episode target prices for MS-DRGs 469 and 470. All providers and suppliers are paid as usual when billing Medicare throughout the year. However, at the end of each CJR performance year (of which we’ve seen approximately five thus far), actual spending for these episodes is compared to the provided Medicare target episode price. Depending on a hospital’s quality score and total episode spending, a participant may receive an additional payment — or be required to repay Medicare a portion of its episode spending.

How is CJR hospital participation decided?

In its first two performance years, the CJR model mandated participation for all IPPS providers within certain CMS-selected regions. But, when the final rule was published on December 1, 2017, participation became voluntary for all rural and low-volume providers and in approximately half the formerly mandated regions as well. CMS reports that for the performance year of 2018, roughly 86 out of 323 total optional participants agreed to take part in CJR for the remaining performance years.

Does CJR target pricing actually reduce episode costs?

Without getting too granular, a quick look into the Definitive databases can give us an interesting insight into the highest average joint replacement costs under Medicare. We can take that information and then reference a list of the highest average joint replacement costs under all payors.

When we open the scope to account for all payors, however, the average payment per claim for major joint replacements jumps up by approximately 300% at $152,433. How much of this massive differential can be attributed to CJR specifically is hard to say — but it appears that CMS is doing something right here, regarding overall cost of care when it comes to major joint replacements.
