Official Description

Necropsy (autopsy), gross and microscopic; with brain

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A necropsy, commonly referred to as an autopsy, is a comprehensive examination performed post-mortem to investigate the cause of death through both gross and microscopic analysis. This procedure may involve the central nervous system, specifically the brain, and is conducted for various purposes, including legal, forensic, clinical, or academic reasons. In forensic contexts, necropsies are crucial for determining the time and manner of death, as well as the events leading up to it. Clinically, they provide valuable insights into the pathological processes of diseases, contributing to the understanding of health standards and potentially preventing future fatalities. The necropsy process begins with an external examination of the body, which may include photographic documentation, assessment of clothing and body positioning, and collection of any relevant substances such as dirt, blood, or chemical residues. Advanced techniques, such as ultraviolet light, may be employed to detect fluid deposits. Additionally, samples of hair and nails can be collected, and radiographic examinations may be conducted to identify any fractures. Following the external assessment, a detailed gross examination of the internal organs is performed, alongside a thorough evaluation of the brain and spinal cord if applicable. Microscopic examination is also a critical component, involving the analysis of fluid and tissue specimens for pathogens, genetic diseases, metabolic disorders, or the presence of drugs and chemicals. Upon completion of the autopsy, the body is carefully prepared for closure, with internal organs returned to the body cavity and incisions meticulously closed. This procedure is essential for providing clarity and understanding in cases of unexplained or suspicious deaths.

1. Indications

The necropsy (autopsy) is indicated for various reasons, including:

  • Forensic Investigation - To determine the time and manner of death and the events leading up to it in legal or criminal cases.
  • Clinical Insight - To ascertain the cause of death and gain a deeper understanding of the pathological processes associated with diseases.
  • Healthcare Standards - To help ensure a standard of healthcare and prevent future deaths by identifying potential health risks or systemic issues.

2. Procedure

The necropsy procedure involves several detailed steps to ensure a thorough examination of the deceased. The process begins with an external examination of the body, where the condition of clothing and body position is noted, and photographs may be taken if deemed appropriate. During this phase, any dirt, blood, or chemical residues present on the body are collected for further analysis. Ultraviolet light may be utilized to identify fluid deposits on the skin or clothing, enhancing the examination's thoroughness. Additionally, samples of hair and nails may be taken for forensic purposes. A radiographic examination can also be performed to detect any new or healing bone fractures, providing further insight into the circumstances surrounding the death.

Following the external examination, a general description of the body is documented, including details such as gender, approximate age, ethnicity, hair color and length, eye color, and distinguishing features like tattoos, scars, moles, and birthmarks. The next step involves a gross examination of the internal organs, which is conducted using the techniques outlined in CPT® Code 88000. This examination includes a detailed assessment of the brain or both the brain and spinal cord, as specified in CPT® Codes 88005 to 88007. After the gross examination, a microscopic examination is performed, where fluid and tissue specimens collected during the autopsy are placed onto slides for microscopic review. These specimens may also be cultured for pathogens and tested for genetic diseases, metabolic disorders, or the presence of drugs or chemicals.

Upon completion of the autopsy, the body cavity is lined with an appropriate material, and the internal organs are sealed in a plastic bag before being returned to the body. The abdomen and chest flaps are then re-approximated and closed, ensuring the body is prepared for any necessary post-procedure handling. The skull flap is replaced in the cranium, and the scalp incision is meticulously closed to maintain the integrity of the body.

3. Post-Procedure

After the necropsy is completed, the body is prepared for final disposition, which may include burial or cremation, depending on the wishes of the family or legal requirements. The findings from the necropsy are documented in a detailed report, which may be used in legal proceedings or for educational purposes. It is essential that all specimens collected during the procedure are properly labeled and stored for any further analysis that may be required. The results of the necropsy can provide critical information that may influence public health policies, clinical practices, and future research initiatives aimed at improving healthcare outcomes.
