Medicare Claims Processing Manual (Pub. 100-04), Ch. 3 § 30.1
Requirements for CAH Services, CAH Skilled Nursing Care Services
30.1 - Requirements for CAH Services, CAH Skilled Nursing Care Services
and Distinct Part Units
(Rev. 771, Issued: 12-02-05, Effective: 01-03-06, Implementation: 01-03-06)
A CAH may provide acute inpatient care for a period that does not exceed, as determined on
an annual average basis, 96 hours per patient. The CAH's length of stay will be calculated
by their A/B MAC (A) based on patient census data and reported to the CMS regional office
(RO). If a CAH exceeds the length of stay limit, it will be required to develop and
implement a corrective action plan acceptable to the CMS RO, or face termination of its
Medicare provider agreement.
Items and services that a CAH provides to its inpatients are covered if they are items and
services of a type that would be covered if furnished by an acute care hospital to its
inpatients. A CAH may use its inpatient facilities to provide post-hospital SNF care and be
paid for SNF-level services if it meets the following requirements:
1. The facility has been certified as a CAH by CMS;
2. The facility operates up to 25 beds for either acute (CAH) care or SNF swing bed
care (any bed of a unit of the facility that is licensed as a distinct-part SNF is not counted
under paragraph (1) of this section); and
3. The facility has been granted swing-bed approval by CMS.
A CAH that participated in Medicare as a rural primary care hospital (RPCH) on September
30, 1997, and on that date had in effect an approval from CMS to use its inpatient facilities to
provide post-hospital SNF care, may continue in that status under the same terms, conditions,
and limitations that were applicable at the time those approvals were granted.
A CAH may establish psychiatric and rehabilitation distinct part units effective for cost
reporting periods beginning on or after October 1, 2004. The CAH distinct part units must
meet the following requirements:
1. The facility distinct part unit has been certified as a CAH by CMS;
2. The distinct part unit meets the conditions of participation requirements for
hospitals;
3. The distinct part unit must also meet the requirements, other than conditions of
participation requirements, that would apply if the unit were established in an acute care
hospital;
4. Services provided in these distinct part units will be paid under the payment
methodology that would apply if the unit was established in an acute care (non-CAH)
hospital paid under the hospital inpatient PPS; Inpatient Rehabilitation Facilities in CAHs are
paid under the Inpatient Rehabilitation Facility PPS (see Pub 100-04, Chapter 3, Section 140
for billing requirements) and the Inpatient Psychiatric Units in CAHs are paid on a
reasonable cost basis until a prospective payment system is created (expected in 2005);
5. Beds in these distinct part units are excluded from the 25 bed count limit for
CAHs;
6. The bed limitations for each distinct part unit is 10; and
If a distinct part unit does not meet applicable requirements with respect to a cost reporting
period, no payment may be made to the CAH for services furnished in the unit during that
period. Payment may resume only after the CAH has demonstrated that the unit meets
applicable requirements.
