Summary of Changes

There are no changes to the original data format or to UMLS source processing.

Source Provided Files:

The input files are in standard comma-separated-values format, with fields descriptions in the first line.

File Name Description

ccs_dx_icd10cm_2017.csv Diagnosis categories and mappings
ccs_pr_icd10pcs_2017.csv Procedure categories and mappings

Identifiers:

Identifiers are assigned as follows:

Identifier TTY Origin

Relationships (MRREL); Hierarchy (MRHIER)


REL RELA

Origin
CHD
PAR
(no RELA) Hierarchy of Multi-level diagnoses and procedures (LVL 1 and LVL2)
RQ classified_as
classifies
Connect ICD-10-CM or ICD-10-PCS with CCS CATEGORY and MULTI CCS LVL 2 atoms
SIB (no RELA) Relationships between codes with the same parents.
SY has_single_level_category
has_multi_level_category
Connect single-level CCS CATEGORY to MULTI CCS LVL 2 categories where there is a one-to-one mapping

Mappings (MRMAP):

Field Value Origin
RELA classified_as Connect ICD-10-CM or ICD-10-PCS with CCS CATEGORY and MULTI CCS LVL 2 atoms. There is overlap between some CCS CATEGORY and CCS LVL 1 CODE values. To disambiguate, note that TOEXPR values do not correspond to MULTI CCS LVL 1 CODES.
