Event Summary Variable ICD-9 Filter

Make selections on this tab to select ICD-9 coded conditions linked to event selections. NOTE: Not all codes listed in the menu below contain data. Please see ICD9CODE's case-count view for a detailed frequency distribution.

For all current conditions, ICD9CODE reports the ICD-9-CM diagnosis code for the condition. To preserve confidentiality, AHRQ offers a version of the ICD-9-CM codes where the fully specified ICD-9-CM codes have been collapsed to 3-digit code categories. For procedure codes, see ICD9PROC. Beginning in 2016, conditions are coded to ICD-10-CM codes, and not ICD-9-CM codes.

ICD9CODE is on the condition record (see RECTYPE for more details on the different record types in IPUMS MEPS). Variables offered on the condition record through IPUMS MEPS are derived from the Medical Conditions file provided by AHRQ. Please see our overview of the event, medical conditions, and prescribed medicines variables, including how those variables are offered through IPUMS MEPS, and general considerations to keep in mind when conducting analyses using these variables.
