Official Description

Necropsy (autopsy), gross and microscopic; without CNS

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

A necropsy, commonly referred to as an autopsy, is a thorough examination of a deceased individual, focusing on both gross and microscopic analysis of the body. This procedure is conducted without including the central nervous system (CNS). The primary purpose of a necropsy can vary; it may be performed for legal or forensic reasons to ascertain the time and manner of death, as well as the events leading up to it. Alternatively, it can serve a clinical or academic purpose, aiming to determine the cause of death, enhance understanding of disease processes, or contribute to healthcare standards that may prevent future fatalities. The process begins with an external examination of the body, which may involve taking photographs, assessing the condition of clothing, and noting the position of the body. Various samples, such as dirt, blood, or chemical residues, are collected for further analysis. Techniques like ultraviolet light may be employed to detect fluid deposits on the skin or clothing. Additionally, samples of hair and nails may be collected, and radiographic examinations can be conducted to identify any new or healing bone fractures. The external examination also includes a detailed description of the body, encompassing aspects such as gender, approximate age, ethnicity, hair color and length, eye color, and any distinguishing features like tattoos, scars, moles, or birthmarks. Following this, a gross examination of the internal organs is performed, adhering to the techniques outlined in the relevant CPT® codes. A microscopic examination is also conducted, which involves placing fluid and tissue specimens onto slides for microscopic review, as well as culturing for pathogens and testing for genetic diseases, metabolic disorders, or the presence of drugs or chemicals. Upon completion of the autopsy, the body cavity is lined with appropriate material, the internal organs are sealed in a plastic bag and returned to the body, and the abdomen and chest flaps are re-approximated and closed. The skull flap is replaced in the cranium, and the scalp incision is subsequently closed. The CPT® Code 88020 specifically reports the performance of an autopsy that includes gross and microscopic examination of the body, explicitly excluding the central nervous system.

1. Indications

The necropsy (autopsy) is indicated for various reasons, including but not limited to the following:

  • Forensic Investigation - Conducted to determine the time and manner of death, as well as the events leading up to the death, often in legal contexts.
  • Clinical Research - Performed to ascertain the cause of death and to gain insights into the pathological processes of diseases.
  • Quality Assurance - Aimed at ensuring standards of healthcare are maintained to prevent future deaths by understanding the circumstances surrounding a death.

2. Procedure

The procedure for conducting a necropsy involves several detailed steps, each critical to the overall examination process:

  • External Examination - The necropsy begins with a thorough external examination of the body. This includes taking photographs, assessing the condition of clothing, and noting the position of the body. Any visible dirt, blood, or chemical residues are collected for further analysis. Techniques such as ultraviolet light may be utilized to identify fluid deposits on the skin or clothing. Additionally, samples of hair and nails may be taken for forensic purposes.
  • Radiographic Examination - A radiographic examination may be performed to detect any new or healing bone fractures, providing insight into potential trauma that may have contributed to the death.
  • General Description - A comprehensive 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.
  • Gross Examination of Internal Organs - Following the external examination, a gross examination of the internal organs is conducted using techniques specified in CPT® Code 88000. This step involves a detailed visual inspection of the organs to identify any abnormalities or signs of disease.
  • Microscopic Examination - A microscopic examination is performed, where fluid and tissue specimens removed during the autopsy are placed onto slides for microscopic review. This may also include culturing specimens for pathogens and testing for genetic diseases, metabolic disorders, or the presence of drugs or chemicals.
  • Closure of the Body - Upon completion of the autopsy, the body cavity is lined with an appropriate material. The internal organs are sealed in a plastic bag and returned to the body. The abdomen and chest flaps are then re-approximated and closed. Finally, the skull flap is replaced in the cranium, and the scalp incision is closed to complete the procedure.

3. Post-Procedure

After the necropsy is completed, the body is prepared for release according to legal and ethical guidelines. The findings from the autopsy are documented in a detailed report, which may be used for legal purposes, clinical research, or educational objectives. The report typically includes the results of both the gross and microscopic examinations, as well as any relevant findings from the external examination. It is essential that all documentation is thorough and accurate to support any potential legal proceedings or further medical investigations.
