Dobson | DaVanzo is proud to share a recent study conducted by our team, published in Prosthetics and Orthotics International, which highlights the impact of providing microprocessor knees (MPKs) to Medicare Fee-for-Service (FFS) K2 beneficiaries (those with above-knee or knee disarticulation amputations who have the ability or potential for ambulation to traverse low level environmental barriers such as curbs, stairs, or uneven surfaces). 

Using Medicare FFS claims data and propensity score weighting techniques, the study found that MPK provision was associated with an 18.5% reduction in injurious falls resulting in a medical claim among K2 beneficiaries. Additionally, provision of MPKs to the K2 beneficiaries led to an average medical cost savings of $1,351 per member per month, amortizing the $25,075 cost difference between MPKs and non-microprocessor knees within 19 months. Over a 10-year period, projected Medicare savings could reach $410.3 million.

These findings contribute to the ongoing policy discussion about Medicare coverage for MPKs in the K2 population. In March 2023, CMS released a draft policy for public comment regarding this coverage, marking an initial step toward potential changes in reimbursement. This study provides new data to inform policymakers and other stakeholders as they consider the implications of expanding MPK coverage for K2 beneficiaries.
