AHA Coding Clinic® for ICD-10-CM and ICD-10-PCS - 2019 Issue 4; New/Revised ICD-10-CM Codes
Exertional Heat Stroke
Unique codes were created to identify heatstroke and sunstroke (T67.01-), exertional heat stroke (T67.02-), and other heatstroke and sunstroke (T67.09-). The change will improve tracking of incidences and outcomes of exertional heat stroke (EHS). In keeping with the current tabular format, the addition of these codes is identified in an initial, subsequent, or sequela phase of diagnosis. EHS is the most severe form of exertional heat illness. It is identified by an elevated core body temperature associated with signs of organ system failure from hyperthermia, and neurocognitive dysfunction. EHS is life threatening and can be fatal...
