Employer-Sponsored Medicare Advantage Plans and the 2018 Therapy Cap Repeal

Le résumé fourni par la source

BACKGROUND: Policy impacting traditional Medicare beneficiaries may have unintended effects for privately insured patients. After the repeal of a longstanding $1500 outpatient therapy cap in 2018, we aimed to evaluate if this policy change was associated with differences in use of cost of postoperative therapy after common hand surgeries, including carpal tunnel release, trigger finger release, ganglion cyst excision, De Quervain tenosynovitis release, carpometacarpal arthroplasty, and distal radius fracture open reduction/internal fixation or percutaneous pinning. METHODS: The Medicare Supplement and Coordination of Benefits files from Marketscan were used. Frequency of therapy appointments, overall costs, and out-of-pocket costs were obtained. A segmented interrupted time series with Poisson and log-transformed linear regression was performed. RESULTS: No significant monthly change in odds of therapy use was found in the postpolicy period for patients who underwent trigger finger release, carpal tunnel release, Ganglion cyst excision, De Quervain tenosynovitis release, carpometacarpal arthroplasty, or distal radius fracture, pinning, or open reduction/internal fixation. Overall cost decreased in the postpolicy period by 2% for comprehensive plans (95% confidence interval [CI]: -0.03 to -0.01, P < 0.001), by 7% for those with exclusive provider organizations (95% CI: -0.10 to -0.04, P < 0.001), by 1% for HMOs (95% CI: -0.01 to 0.002, P = 0.01), and by 3% for preferred provider organizations (95% CI: -0.03 to -0.02, P < 0.001). In the postpolicy period, no monthly change in out-of-pocket cost was observed for patients with comprehensive, exclusive provider organization, health maintenance organization, preferred provider organization, or point of service with capitation insurance plans. CONCLUSIONS: Patients with employer-sponsored Medicare Advantage plans experienced increased out-of-pocket costs for therapy despite lower net costs. These data highlight an urgent need for policy ensuring that patients benefit when overall costs of care decrease.
