Summary & Overview
CPT 88029: Neonatal/Stillborn Postmortem Pathology, Including Brain
CPT code 88029 represents a comprehensive postmortem pathology examination of a stillborn or newborn after death, including gross and microscopic evaluation of the brain. This code captures a specialized diagnostic service performed by pathologists and is essential for determining causes of perinatal mortality, informing family counseling, and guiding public health reporting. Nationally, accurate coding of neonatal autopsy services supports mortality surveillance, research into causes of infant death, and quality metrics related to perinatal care.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines payer coverage patterns, coding and billing considerations, and clinical context for the procedure.
Readers will learn what the code represents, typical clinical and facility settings where the service is performed, and the implications for documentation and claims submission. The report also reviews benchmarks and policy considerations relevant to neonatal postmortem examinations, and highlights areas where clear documentation is critical for correct code assignment. Data not available in the input is explicitly noted where applicable.

Clinical & Coding Specifications
Clinical Context
A perinatal pathology consultation is requested after the delivery of a stillborn infant in a tertiary hospital labor and delivery unit. The obstetric team stabilizes the mother and places the infant under the care of the pathology service for postmortem assessment. The provider performing 88029 conducts a full gross and microscopic autopsy-style evaluation of the newborn, including systematic examination of the brain. The workflow includes: consent and documentation from the mother or legal guardian; receipt of the infant and clinical history (maternal prenatal course, fetal monitoring, labor and delivery events, and any antenatal imaging); external inspection and anthropometrics; evisceration and organ gross evaluation with particular attention to neuropathology; representative tissue sampling for histology; preparation of microscopic slides; and a final pathology report integrating gross and microscopic findings with clinical data. Communication occurs with obstetrics, neonatology, and the family; ancillary testing such as placental pathology, microbiology cultures, genetic testing, or toxicology may be ordered separately and billed under their own codes.
