Medicare contractors will temporarily delay the release of all home health low utilization payment adjustments ( LUPA) claims with "through" dates on or after January 1, 2014. The hold is due to Medicare contractors’ identification of an incorrect payment calculation involving these claims, CMS announced on Jan. 16. The hold, which is designed to prevent inaccurate payments will remain in place until the problem is corrected, after which Medicare contractors will release the claims.. CMS anticipates that the correction will be completed on Feb. 10.
