Highlights
- •Research on the prevalence and co-occurrence of common pain conditions is needed
- •ICD-10-CM introduced challenges to assessing pain condition prevalence over time

- •It was assessed based on stability of prevalence estimates and patient demographics
- •Offers a standard tool for health services and epidemiologic research on pain
Abstract
Effective management of patients with pain requires accurate information about the
prevalence, outcomes, and co-occurrence of common pain conditions. However, the transition
from ICD-9-CM to ICD-10-CM diagnostic coding in 2015 left researchers without methods
for comparing the prevalence of pain conditions before and after the transition. In
this study, we developed and assessed a diagnostic framework to serve as a crosswalk
between ICD-9-CM and ICD-10-CM diagnosis codes for common pain-related health conditions.
We refined existing ICD-9-CM definitions for diagnostic clusters of common pain conditions
consistent with the US National Pain Strategy and developed corresponding ICD-10-CM
definitions. We then assessed the stability of prevalence estimates and associated
patient socio-demographic features of each diagnostic cluster during 1-year periods
before and after the transition to ICD-10-CM in 3 US health care systems using electronic
health records data for in-person encounters. Prevalence estimates and socio-demographic
characteristics were similar before and after the transition. The Pain Condition ICD-9-CM
to ICD-10-CM Crosswalk includes a full spectrum of common pain conditions to enable
prevalence estimates of multiple and chronic overlapping pain conditions. This allows
the tool to serve as a foundation for a broad array of pain-related health services
research utilizing electronic databases.
Perspective
This article details the development and assessment of the Pain Condition ICD-9-CM
to ICD-10-CM Crosswalk, a diagnostic framework for assessing pain condition prevalence
across the ICD-9-CM to ICD-10-CM transition. This framework can serve as a standardized
tool for research on pain conditions, including health services and epidemiologic
research.
