Clinical & Coding Specifications
Clinical Context
A decedent is brought to the medical examiner's office after an unexpected out-of-hospital death. The forensic pathologist performs a comprehensive forensic necropsy to determine cause, manner, and approximate time of death, document injuries, and assist with identification when needed. The workflow begins with scene and law-enforcement information review, external examination and photography, collection of fingerprints and identifying data, and directed internal examination with organ dissection. Ancillary testing (toxicology, histology, microbiology, radiology) is ordered based on findings. Findings are documented in a signed autopsy report; specimens are retained or released per jurisdictional policy. Typical sites of service include medical examiner or coroner offices, hospital pathology departments when requested by legal authorities, and forensic pathology centers. Typical patient scenarios include sudden unexplained deaths, suspected homicide, accidental traumatic deaths, unattended deaths, deaths in custody, or cases requiring legal identification.
