LAST EDITED: JUL 17, 2016
HELP-PROMPT: Enter the 2 digit MDC identifier.
DESCRIPTION: The MDC ID is the standard MDC identifier. The MDC is the highest level grouping of related DRGs.
MDC's 00 - 25 are CMS defined. MDC 00 are the Pre-MDC Categories and MDC 99 are the Procedure
Unrelated to Principal Diagnosis Categories.
TECHNICAL DESCR: The Procedure Unrelated to Principal Diagnosis Categories are defined under MDC 99 for logical and
grouping purposes.

INPUT TRANSFORM: K:+X'=X!(X>1000)!(X<0)!(X?.E1"."1N.N) X
LAST EDITED: AUG 13, 2019
HELP-PROMPT: Enter a number that will uniquely identify this Category within the MDC.
DESCRIPTION: The Category ID is an assigned number that provides a unique identifier for the Category within an
MDC. The Category is the second level grouping of related DRGs. The Category ID combined with the
MDC ID creates a unique identifier for the MDC-Category subgroup.
The top level of an MDC is assigned a Category of 0. The Diagnosis assigned to this Category
together define the MDC group and may be used by one or more (or no) other Category within the MDC.
There are no DRGs assigned to this level.
TECHNICAL DESCR:
The Category ID is a simple counter (0:1) of Categories within an MDC.
83,.04 MDC TYPE 0;4 SET
'0' FOR UNLIMITED;
'1' FOR EXCLUSIVE;
'2' FOR GENERAL;
LAST EDITED: JUL 29, 2019
HELP-PROMPT: Enter the Type of this MDC indicating the relative exclusivity or restrictions.
DESCRIPTION: The MDC Type defines the relationship between MDCs when DRGs across multiple MDCs are satisfied.
Given that an MDC/DRG Case is satisfied but is rejected because of extraneous Operating Room
Procedures then the MDC Type indicates which other MDC/DRGs are allowed. The value applies to all
DRGs within an MDC. Overrides the DRG Hierarchy.
UNLIMITED MDCs (00, 99) are allowed with all other MDCs. EXCLUSIVE MDCs (24, 25) are those when a
DRG Case is satisfied then only DRGs from that MDC and Unlimited are allowed, all others are
rejected. GENERAL MDCs (01-23) have no restrictions. If a DRG Case is satisfied but rejected due
to OR procedures then the next satisfied DRG is allowed, regardless of its MDC.
Primary affect is if a DRG from an Exclusive MDC (24, 25) is satisfied then all General MDC/DRGs
(01-23) are rejected, bypassing the order of precedence.
