ICD-Mappings

This python tool enables a variety of mappings of ICD codes (International Classification of Diseases) to different medical concepts with a single line of code.

Supported Mappings

From ICD-9 CM diagnostic codes to:

• ICD-10 CM: International Classification of Diseases version 10 Clinical Modification.
• CCS: Clinical Classification Software. Has a universe of just 283 diagnostic categories.
• CCI: Chronic Condition Indicator. True or False whether the diagnostic is chronic.
• ICD-9 Chapters: 19 Chapters of ICD-9 CM.

From ICD-10 CM diagnostic codes to:

• ICD-9 CM: International Classification of Diseases version 9 Clinical Modification
• ICD-10 CM Chapters: 22 Chapters of ICD-10 CM.
• CCS(R): Clinical Classification Software (Refined). All the 70k ICD-10-CM diagnostic codes can be mapped into just 530 clinical categories.
• CCI(R): Chronic Condition Indicator (Refined). True or False Whether the diagnostic is chronic.

Installation

pip install icd-mappings

Usage

from icdmappings import Mapper

mapper = Mapper()

icd9code = '29410' 
mapper.map(icd9code, source='icd9', target='ccs')
>>> '653'

# you can pass any Iterable of codes (list, numpy array, pandas Series, you name it)
icd9codes = ['29410', '5362', 'NOT_A_CODE', '3669']
mapper.map(icd9codes, source='icd9', target='ccs')
>>> ['653', '141', None, '86']

# which of these diagnostics are chronic?
mapper.map(icd9codes, source='icd9', target='cci')
>>> [True, False, None, True]

# icd9 to icd10
mapper.map(icd9codes, source='icd9', target='icd10')
>>> ['F0280', 'R111000', None, 'H269']

# And many more... You can check all available mappers this way
mapper.show_mappers()
>>> From icd9 to:
>>>        - icd10
>>>        - ccs
>>>        - cci
>>>        - chapter
>>> From icd10 to:
>>>        - icd9
>>>        - chapter
>>>        - ccsr
>>>        - ccir
