Diagnosis Related Groups (MS-DRG), additions, deletions, or
alterations to MS DRGs can affect how hospitals should

hospice being included as impacted by the rule.
• Transfers to 50 (hospice home) and 51 (hospice inpatient) with a

childbirth and puerperium were reclassified as
antepartum conditions.
12. The areas that are impacted predominantly with
the severity shift are Neoplasms, Circulatory
System, Skin and Subcutaneous Tissue,
Genitourinary Systems, Injury and Poisoning, and
Factors Influencing Healthcare Status.
Bronchoalveolar lavage, percutaneous drainage of
the pelvic cavity and percutaneous removal of a
drainage device are all moved from an OR
category to a Non-OR classification.
These changes impact the
DRG changes and moved their
corresponding classifications.

will be impacted by the transfer policy.
This represents a drop in 2 DRGS that
will be impacted by the rule.

on the additional ICD-10 codes,
there were changes to the DRGs
impacted by the transfer policy.
15. MS–DRGs 273 and 274 are currently subject to the post-acute care transfer
policy and are being removed from the list for 2020.

transfer policy revised and do not qualify in 2020, even though they were
reclassified.
The new MS–DRGs 319 and 320 also do not qualify to be included on the
list of DRGs that are subject to the post-acute care transfer policy.
16. MS DRG changes can affect how Transfer DRG
underpayments and overpayments are properly
recovered.
Without displacing or disrupting a current review
vendor or internal process, BESLER can provide a
secondary validation of impacted transfer claims
to ensure you are identifying all potential
underpayments and overpayments.
