Development and validation of new multimorbidity-weighted index for ICD-10-coded electronic health record and claims data: an observational study.

ABSTRACT:

Objective

Map multimorbidity-weighted index (MWI) conditions to International Classification of Diseases, 10th Revision (ICD-10), expand the conditions and codes to develop a new ICD-10-coded MWI (MWI-ICD10) and updated MWI-ICD9, and assess their consistency.

Design

Population-based retrospective cohort.

Setting

Large medical centre between 2013 and 2017.

Participants

Adults ≥18 years old with encounters in each of 4 years (2013, 2014, 2016, 2017).

Main outcome measures

MWI conditions mapped to ICD-10 codes, and additional conditions and codes added to produce a new MWI-ICD10 and updated MWI-ICD9. We compared the prevalence of ICD-coded MWI conditions within the ICD-9 era (2013-2014), within the ICD-10 era (2016-2017) and across the ICD-9-ICD-10 transiti
