November 18, 2016 -- CMS contracted with Abt Associates to
reassess the current HHPPS model and develop an alternative
payment model that better aligns patient needs and payments
• Abt Associates published: Overview of the Home Health
Grouping Model (HHGM)
• Setup of HHGM
– 30 day periods
– Timing
– Referral Source
– Clinical Groupings
– Functional and cognitive level
– Comorbidity adjustment

8. 8
• Implementation date proposed to be for periods of care
beginning on or after January 1, 2020
• Budget neutral – huge win compared to the estimated
$950M reduction in payment of HHGM
• Replaces 60-day payment episodes with 30-day periods
• Eliminates the use of the number of therapy visits in
payment determination
CY 2019 Proposed Rule
What is PDGM?
August 2018 Leadership Conference
9. 9
• Increase total number of case-mix weights from 153 to
216
• Modification to low utilization payment adjustments
(LUPAs)
• Model based on claims with through dates in 2017 that
were processed by March 2, 2018
– 6,771,059 episodes
– 959,410 (14.2%) excluded due to non-linked OASIS
– 7,458 cost reports

• February 9, 2018 - Bipartisan Budget Act of 2018 signed
into law
• SEC. 51001. Home Health Payment Reform:
– Budget neutral HH payment reform by 2020
– Transition to a 30-day Unit of Payment for Home Health
Services
– Elimination of the use of therapy thresholds in case mix
adjustment factors for calculating payments
– Annual review to determine the impact of differences
between assumed behavior changes and actual behavior
changes
Home Health Groupings Model (HHGM)
What is PDGM?
August 2018 Leadership Conference
13. 13
• Proposed PDGM:
– 30-day periods
– The first 30 day episode would be defined as early and all
subsequent episodes would be classified as late
– A 30-day period could not be considered early unless there
was a gap of more than 60 days between the end of one
period and the start of another
Episode Timing
PDGM Details
August 2018 Leadership Conference
14. 14
• Estimated 25% of all episodes are less than 30 days
– 73% of episodes completed within 60 days
Reasons for 30-Day Periods

Current PPS:
• Episode timing
– Early
– Late
• Therapy thresholds
– 0 to 13
– 14 to 19
– 20+
Admission Source
PDGM Details
August 2018
Proposed HHGM:
• Admission timing
– Early
– Late
• Admission source
– Community
– Institutional
Leadership Conference
16. 16
• Patients discharged from an institutional setting (inpatient
hospital, SNF, IRF, LTCH) in the prior 14 days will be defined as
institutional and all others as community
• Second periods with an institutional discharge within 14 days of
the SOC would be considered community
Admission Source
PDGM Details
August 2018 Leadership Conference
17. 17
Institutional
• 1.4 episodes per patient
• Higher initial resource use
Community
• 2.6 episodes per patient
• Lower initial resource use
• More likely to have chronic conditions, therefore more likely to
require ongoing but less resource-intensive care
Reasons for Admission Type
PDGM Details
August 2018 Leadership Conference
18. 18
Current PPS:
• Based on clinical severity levels based on 13 OASIS assessment
items
Proposed HHGM:
• 30-day periods are grouped into six clinical groups based on
principle diagnosis
Clinical Grouping
PDGM Details
August 2018 Leadership Conference
19. 19
• Nineteen percent (19%) of the 30-day periods were considered
Questionable Encounters (QE)
• If a 30-day period of care could not be grouped based on the
home health reported principal diagnosis, the claim would be
returned to the provider for more accurate coding
Clinical Grouping
PDGM Details
August 2018 Leadership Conference
20. 20
• Concerns that MMTA was a “catch all” diagnosis group
• Proposed rule addressed this and indicated diagnosis
subgroups showed fairly equal resource use
Clinical Grouping
PDGM Details
August 2018 Leadership Conference
21. 21
Current PPS:
• Classified into 1 of 3 functional levels based on six OASIS
assessment items
• Functional levels based on points:
– Low, Medium, High
Proposed PDGM:
• Classified into 1 of 3 functional levels based on eight OASIS
assessment items

Proposed PDGM:
• The PDGM Model includes a comorbidity adjustment based on
the presence of a secondary diagnosis. The home health specific
comorbidity list includes 13 broad categories with 116
subcategories. Of those 116 subcategories, 11 are included in the
comorbidity adjustment of the PDGM:
Comorbidity Adjustment
PDGM Details
August 2018 Leadership Conference
26. 26
• Further analysis of subgroups was completed to determine which
interactions (diagnoses from two subgroups) had a clinically and
statistically significant relationship with increased resource utilization
• 343 different subgroup interactions
– 187 had significant difference in resource use
• 27 had value that exceeded $150
– $150 used as approximately 3 times the median value for the
individual subgroups
Comorbidity Adjustment

Three Levels Proposed:
1. No
2. Low
3. High
• Low - Secondary Diagnosis within one of the subgroups
listed in table 44
• High - Two or more Secondary Diagnosis within the 27
subgroups listed in table 45
*Can be only one of the above (can’t be Low AND High)
Comorbidity Adjustment

Case Mix

32. 32
Current PPS:
• 60-day episode with four or fewer total visits are paid per visit
Proposed PDGM:
• LUPAs now have variable thresholds based on HHRG
– Different level for each of the 216 HHRGs
– 10th percentile value of visits for each threshold
– LUPA Thresholds by visits:
LUPAs
PDGM Details
August 2018
– LUPA add-on remains
Leadership Conference

Supplies
• NRS Add-on payments eliminated
• Estimated 60% of CY2017 episodes did not contain NRS
• Additional Clinical Groupings to account for high NRS use
– Wound – 9% of estimated periods
– Complex Nursing – 4% of estimated periods
• 27% of periods with NRS use
• 44% of NRS cost
Miscellaneous

• For billing purposes, PDGM proposes to keep the RAP/final
claim billing methodology
– CMS estimates the median time to submit a RAP is 12 days so they
are soliciting comments on if this makes sense
– Potential Notice of Admission to establish the agency as primary if
RAPs are eliminated
• OASIS still completed every 60 days
• PEPs (Partial Episode Payments) have same methodology
• Outliers have same methodology, although fixed dollar loss
would need to change
– Based on current rules, 4.77% of estimated total payments would be
outlier dollars
• CMS requirement that number cannot exceed 2.5%
