Code classification for CCS

Description

The CCS classification for ICD-9 and ICD-10 codes is a procedure categorization scheme that can employ in many types of projects analyzing data on procedures

Usage

icdPrToCCS(
  prDataFile,
  idColName,
  icdColName,
  dateColName,
  icdVerColName = NULL,
  icd10usingDate = NULL,
  isDescription = TRUE
)

icdPrToCCSLvl(
  prDataFile,
  idColName,
  icdColName,
  dateColName,
  icdVerColName = NULL,
  icd10usingDate = NULL,
  CCSLevel = 1,
  isDescription = TRUE
)

Arguments

prDataFile	A data frame object of clinical procedure data with at least 3 columns: ID, ICD, and Date. As for date column, the data format should be YYYY/MM/DD or YYYY-MM-DD.
idColName	Column name of ID column in prDataFile. Data type of this argumant should be string without quotation marks.
icdColName	Column name of ICD column in prDataFile. Data type of this argumant should be string without quotation marks.
dateColName	Column name of date column in prDataFile (with date in YYYY/MM/DD or YYYY-MM-DD format). Data type of this argumant should be string without quotation marks.
icdVerColName	(Optional) Column name of ICD-9/10 version recorded in prDataFile. Data format in this column should be numeric 9L or 10L.
icd10usingDate	The date that ICD-10 was started to be used in prDataFile dataset. The data format should be YYYY/MM/DD or YYYY-MM-DD. Necessary if icdVerColName is null.
isDescription	Binary. If true, category description of classification methods will be used in the group column. If false, category name will be used. By default, it is set to be True (standard category description).
CCSLevel	Numeric. Used for multi-level CCS. By default, it is set to 1. There is 3 multi-level CCS (1~3) for ICD-9, and 2 multi-level CCS (1 and 2) for ICD-10.

Details

These CCS functions collapse ICD codes into a smaller number of clinically meaningful categories that are more useful for presenting descriptive statistics than individual ICD procedure codes are.

Value

Two new data.tables. 1) groupedDT: Based on prDataFile with two new columns for uniform format procedure codes and classified standard categories. 2) Error: Potential error codes from prUniform.

Examples

# sample file for example

head(samplePrFile)

# Group procedure codes into single level of CCS classification

icdPrToCCS(samplePrFile, ID, ICD, Date, icdVerColName = NULL, "2015-10-01", TRUE)

# Group procedure codes into multiple levels of CCS classification

icdPrToCCSLvl(samplePrFile, ID, ICD, Date, icdVerColName = NULL, "2015-10-01", 2, TRUE)
