Update Notification)
Financial limitations on outpatient therapy services, as described above, began for
therapy services rendered on or after on January 1, 2006. References and polices relevant
to the exceptions process in this chapter apply only when exceptions to therapy caps are
in effect. For dates of service before October 1, 2012, limits apply to outpatient Part B
therapy services furnished in all settings except outpatient hospitals, including hospital
emergency departments. These excluded hospital services are reported on types of bill
12x or 13x, or 85x. Effective for dates of service on or after October 1, 2012, the limits
also apply to outpatient Part B therapy services furnished in outpatient hospitals other
than CAHs and hospitals in Maryland. During this period, only type of bill 12x claims
with a CMS certification number in the CAH range, type of bill 12x and 13x claims with
a CMS certification number beginning with the State code for Maryland, and type of bill
85x claims are excluded.
Effective for dates of service on or after January 1, 2014, the limits also apply to CAHs.
Effective for dates of service on or after January 1, 2016, the limits also apply to hospitals
in Maryland. Effective for dates of service on or after January 1, 2018, the KX modifier
threshold applies to all the therapy provider types to which the limits applied.
Contractors apply the financial limitations or thresholds to the MPFS amount (or the
amount charged if it is smaller) for therapy services for each beneficiary.
As with any Medicare payment, beneficiaries pay the coinsurance (20 percent) and any
deductible that may apply. Medicare will pay the remaining 80 percent of the limit after
the deductible is met. These amounts will change each calendar year.
Medicare shall apply these financial limitations or KX modifier thresholds in order,
according to the dates when the claims were received. When limitations or KX modifier
thresholds apply, the Common Working File (CWF) tracks them. Shared system
maintainers are not responsible for tracking the dollar amounts of incurred expenses.
In processing claims where Medicare is the secondary payer, the shared system takes the
lowest secondary payment amount from MSPPAY and sends this amount on to CWF as
the amount applied to therapy limits or KX modifier thresholds.
