This affects episode payment models for cardiac rehabilitation and changes to the comprehensive care model for joint replacement.
The final rule issued Thursday finalizes a delay of the bundled regulations from July 1, 2017 to January 1, 2018.
The Centers for Medicare and Medicaid Services said in the final rule that it had received numerous comments widely supporting the need for more preparation time.
CMS had asked for comments about pushing the bundles to 2018, in the rule announcing the delay to May 20.
The department suggested that more time would allow providers to prepare for the necessary changes in coordination.
The bundled payment models that were put into place under President Obama, implement new Medicare episode payment models for cardiac rehabilitation and changes to the existing joint replacement model.
The models affected acute care hospitals in certain geographic areas, and includes care through 90 days of hospital discharge.
CMS received 47 responses on the start date during a 30-day comment period for the rule that closed on April 19.
Some commenters expressed concern about the delay for its potential impact on clinicians' participation in the 2017 Advanced APM track and for confusion among participants and beneficiaries.
Commenters also expressed concern that a further delay would prevent non-physician practitioner group practices, therapy group practices, therapists in private practice, and comprehensive outpatient rehabilitation facilities, from becoming comprehensive joint replacement collaborators during 2017.
