CPT 88028: Infant Postmortem Examination, Technical Component

CPT code 88028 represents the technical component of an infant postmortem examination, encompassing gross and microscopic analysis of the body and brain after death. This code is used by pathology and laboratory services to bill for the hands-on, technical processes required to prepare, examine, and document tissues in infant autopsy cases. Nationally, accurate coding for postmortem pathology supports vital statistics, medical-legal determinations, and quality assurance in perinatal and neonatal care.

Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for infant autopsy technical services, typical sites of service, and how CPT code 88028 fits into pathology billing. The publication outlines common billing considerations, related service lines, and typical modifier use where available. It also provides benchmarking and policy context relevant to payers and providers, and highlights areas where coding clarity affects claims processing and reimbursement consistency.

The piece is intended for billing professionals, pathology departments, medical examiners, and payer policy teams seeking a practical reference on CPT code 88028 and its role in postmortem infant examinations.

Clinical & Coding Specifications

Clinical Context

A realistic patient scenario involves the unexpected death of a neonate or infant found in a hospital or out-of-hospital setting where an autopsy is requested to determine cause and manner of death. Typical workflow: the infant is pronounced deceased in the neonatal intensive care unit (NICU) or emergency department; the attending physician or coroner/medical examiner requests a postmortem examination. The pathology team receives the body, documents external findings, and performs a complete autopsy including gross examination of the thoracic and abdominal organs and detailed examination of the brain. The technical component includes tissue fixation, gross dissection, processing of representative sections, slide preparation, and routine microscopic review. The final pathology report documents gross and microscopic findings, ancillary studies performed (toxicology, microbiology, or molecular testing as ordered), and a pathologic opinion on cause and manner of death. Family counseling and release of the body follow institutional and jurisdictional policies.

Coding Specifications

Modifier	Description	When to Use
`00`	Unmodified procedure	Standard use when no modifier applies to the technical autopsy service
`26`	Professional component	When billing solely for the pathologist's interpretive report separate from the technical autopsy work
`TC`	Technical component	When billing only for the technical services (specimen processing, slide preparation) associated with the autopsy
`22`	Increased procedural services	When the autopsy requires substantially greater work, time, or complexity than typical (documented)
`52`	Reduced services	When portions of the autopsy are omitted or limited (documented)
`53`	Discontinued procedure	When the autopsy is started but discontinued for documented safety, legal, or family request reasons
`90`	Reference lab	When specimens are sent to an external laboratory and the performing facility bills only as a reference lab
`78`	Unplanned return to the operating/procedure room	Rarely used; when return to the autopsy suite is required for additional procedures during the same encounter due to complication or new finding
`62`	Two surgeons or co-surgeons	Uncommon for autopsy but used if two pathologists share equally the technical work and payer requires co-surgeon reporting
`53`	Procedure discontinued	(Listed again for emphasis) Use when autopsy aborted prior to completion; document reason

Taxonomy Code	Specialty	Notes
207R00000X	Anatomic and Clinical Pathology	Pathologists who perform autopsy examinations and issue the final report
207L00000X	Anatomic Pathology	Specialists focusing on postmortem gross and microscopic examination
2080P0006X	Pediatric Pathology	Pathologists with subspecialty expertise in neonatal and infant postmortem examinations
207K00000X	Forensic Pathology	Pathologists who perform medicolegal autopsies under coroner/medical examiner jurisdiction
207T00000X	Clinical Pathology	Provides ancillary laboratory correlation and testing during autopsy workflow
