NAME

Medical::ICD10 - ICD10 Wrapper module

VERSION

Version 0.05

SYNOPSIS

The International Statistical Classification of Diseases and Related Health Problems 10th Revision (ICD-10) is a coding of diseases and signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or diseases, as classified by the World Health Organization. (WHO). The code set allows more than 14,400 different codes and permits the tracking of many new diagnoses.

You can find more information about ICD10 at: http://www.who.int/classifications/icd/en/

The NHS provides the ICD10 codes as a flat tab separated file which can be obtained from the Connecting For Health Data Standars helpdesk at: http://www.connectingforhealth.nhs.uk/systemsandservices/data/clinicalcoding/codingstandards/icd-10/icd10_prod

This module is designed to parse that file and provide a wrapper around the ICD10 classification codes.

use Medical::ICD10;

my $MICD = Medical::ICD10->new();

$MICD->parse( "/path/to/tsv/file/with/codes.txt" );

## Get an individual term

my $Term = $MICD->get_term( 'A809' );
my $description = $Term->description; # "Acute poliomyelitis, unspecified"

## Get the terms parent

my $ParentTerm = $MICD->get_parent_term_string( 'A809' );
   
## Get all the parents from the term

my $ra_parent_terms = $MICD->get_parent_terms( 'A809' );
my $ra_parent_terms = $MICD->get_parent_terms_string( 'A803' );
   
## Get all the children of the term

my $ra_child_terms = $MICD->get_child_terms_string( 'A809' );
my $ra_child_terms = $MICD->get_child_terms( 'B27' );

METHODS

new

Creates a new instance of the module.

my $MICD = Medical::ICD10->new();

parse
