Summary & Overview
CPT 0554U: Smart PGT–SR 24-Chromosome Embryo Analysis
Headline: New CPT code 0554U identifies a proprietary comprehensive chromosomal analysis for IVF embryos
Lead: CPT code 0554U designates the Smart PGT–SR proprietary laboratory test used to assess all 24 chromosomes in trophectoderm biopsies of in vitro fertilization (IVF) embryos, reporting aneuploidy, abnormal ploidy, mosaicism and a mitochondrial DNA score with accompanying quality control data.
CPT code 0554U represents a PLA code tied to a unique manufacturer-specific test (Igenomix®/Vitrolife Group™ and Thermo Fisher Scientific). Nationally, this code matters because it standardizes billing for an advanced reproductive genetics service that informs embryo selection during IVF. Payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise overview of the clinical purpose and lab workflow behind the code, coverage and payer considerations, common claim modifiers, and benchmarking context where available. The publication summarizes what the code measures (24-chromosome analysis from trophectoderm biopsy, mitochondrial DNA scoring, and quality control reporting), typical service setting (reproductive medicine and specialized fertility laboratories), and the relevance of proprietary PLA coding for billing consistency and payer policy alignment. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0554U is a Proprietary Laboratory Analyses (PLA) code for the Smart PGT–SR test offered by Igenomix®, part of Vitrolife Group™, and Thermo Fisher Scientific. The test analyzes 24 chromosomes from a trophectoderm biopsy of an in vitro fertilization (IVF) embryo to detect chromosomal abnormalities such as aneuploidy, abnormal ploidy (for example, triploidy or haploidy), and mosaicism. The service also provides a mitochondrial DNA score and includes quality control results to support test accuracy.
Service type: Genetic/embryo chromosomal analysis for IVF embryos.
Typical site of service: Reproductive medicine laboratories and specialized fertility clinic-associated laboratories performing embryo biopsy and sequencing-based testing.
Clinical & Coding Specifications
Clinical Context
A 35-year-old patient undergoing in vitro fertilization (IVF) elects to have comprehensive chromosomal screening of blastocyst-stage embryos prior to transfer. During the IVF cycle, embryos reach the blastocyst stage and a trophectoderm biopsy is performed by the embryology team to collect a small number of outer-layer cells. The specimen is sent to the laboratory performing the proprietary Smart PGT–SR test (0554U) to assess all 24 chromosomes for aneuploidy, abnormal ploidy (for example, triploidy or haploidy), and mosaicism. The report also includes a mitochondrial DNA score and quality control metrics. Typical workflow steps: embryo biopsy in the assisted reproductive technology (ART) clinic or IVF laboratory; specimen labeling and shipment under chain-of-custody procedures to the performing lab; laboratory processing, sequencing/analysis, and bioinformatic interpretation; electronic delivery of results to the ordering reproductive endocrinologist and genetic counselor; incorporation of results into embryo selection counseling and the decision for transfer, cryopreservation, or disposal. Typical site of service: outpatient fertility clinic, IVF laboratory, or the performing reference molecular genetics laboratory.

00 | Default/no modifier | Use when no special reporting modifier applies; standard service reporting. |
22 | Increased procedural services | Use when testing required substantially greater work, complexity, or resources beyond typical for the assay (document rationale and additional costs). |
52 | Reduced services | Use when the test was partially reduced or not completed as usually described (document reason such as inadequate sample). |
53 | Discontinued procedure | Use if testing was started but discontinued due to specimen failure or other unrecoverable interruption. |
