Health Indicator Report of Carbon Monoxide Poisoning Mortality

Death is the most severe outcome of carbon monoxide (CO) poisoning. Unintentional CO poisoning deaths are almost entirely preventable. These data can be used to assess the burden of severe CO poisoning, monitor trends over time, and inform prevention, education, and evaluation efforts. To learn more about how to prevent CO exposure, go here:


The source of data is the New Mexico Linked Multiple Cause of Death File provided by the New Mexico Department of Health, Bureau of Vital Records and Health Statistics. The following International Classification of Diseases, 10th Revision (ICD-10) codes were used to identify deaths where CO poisoning was listed as the cause of death: T58 and the underlying cause of death was in the following range of ICD-10 codes: X00-X09 (unintentional fire-related CO poisoning death); V01-W99, X10-X59, Y85-Y86 (unintentional non-fire related CO poisoning death); and Y10-Y34 (CO poisoning of unknown intent).

  • Population Estimates: University of New Mexico, Geospatial and Population Studies (GPS) Program,

Data Interpretation Issues

This indicator and measures underestimate the burden of CO poisoning because most cases of CO poisoning do not result in death. Rates can be misleading (i.e., may not reflect risk of occurrence) if relatively large proportion of deaths occur to non-residents poisoned in New Mexico (they are excluded from the rate calculation).


Carbon monoxide (CO) poisoning mortality refers to deaths of New Mexico residents due to CO poisoning that occurred during a specified time period. CO poisoning deaths include the following categories: unintentional non-fire related; unintentional fire-related; and unknown (previously called undetermined) intent. This indicator utilizes multiple cause coded deaths because CO poisoning mortality is always found as a contributing cause of death, rather than an underlying cause. Measures include 1) the number of deaths from CO poisoning; 2) crude rate of death from CO poisoning; and 3) age-adjusted rate of death from CO poisoning (adjusted by the direct method to the 2000 US standard population). All rates are expressed per 100,000 persons.
