Summary & Overview
CPT 0252U: POC NGS and STR Analysis for Aneuploidy
CPT code 0252U designates a Proprietary Laboratory Analyses (PLA) test for products of conception (POC) performed by Igenomix® USA. The assay combines next generation sequencing (NGS) and short tandem repeat (STR) analysis to detect chromosomal abnormalities (aneuploidy) in tissue from a miscarriage. As a PLA code, 0252U applies to a single manufacturer-specific test and is used for detailed genetic evaluation after fetal loss.
Key payers examined include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Coverage and reimbursement handling for PLA codes can vary by payer, making CPT code 0252U relevant for payers, laboratories, and clinicians involved in miscarriage workups and genetic counseling.
Readers will find a concise overview of the code’s clinical purpose and service setting, payer coverage landscape, and the types of benchmarks and policy considerations typically relevant to PLA molecular diagnostics. The publication highlights where payers commonly focus—clinical indications for testing, documentation requirements, and claims processing nuances for proprietary laboratory codes—alongside national context for the increasing use of NGS-based POC testing in reproductive loss evaluation. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 0252U is a Proprietary Laboratory Analyses (PLA) code for a products-of-conception (POC) test developed by Igenomix® USA. The test uses next generation sequencing (NGS) combined with short tandem repeat (STR) analysis to evaluate tissue from a miscarriage for chromosomal abnormalities (aneuploidy) that may have caused fetal death.
Service Type: Laboratory diagnostic test — molecular/genetic analysis
Typical Site of Service: Clinical laboratory or specialized molecular diagnostics laboratory; specimen collection may occur in outpatient or hospital settings
Clinical & Coding Specifications
Clinical Context
A 33-year-old woman presents to her obstetrician after a first-trimester spontaneous miscarriage at 10 weeks gestational age. Following uterine evacuation (suction curettage) in an outpatient ambulatory surgery center, placental and fetal tissue (products of conception, POC) are submitted to the laboratory for genetic analysis. The clinician orders the proprietary POC test reported under 0252U (Igenomix® USA), which uses next generation sequencing (NGS) and short tandem repeat (STR) analysis to evaluate for chromosomal abnormalities (aneuploidy) and to detect maternal cell contamination. The typical clinical workflow: the surgical team collects POC tissue into appropriate sterile containers and completes a requisition with clinical history and gestational age; the specimen is shipped to the reference laboratory under required conditions; the lab performs NGS plus STR analysis; a signed molecular pathology report is returned to the ordering provider with results and interpretation to inform recurrence risk counseling and possible further reproductive evaluation.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
00 | Unspecified | Rarely used; reserved for payor-specific reporting when no other modifier applies |
22 | Increased procedural services | Use if extraordinary work or complexity in specimen handling or additional testing beyond standard protocol |
26 | Professional component | Use when billing only the professional interpretation component separately from technical services |
52 | Reduced services | Use if testing was partially performed or limited by specimen inadequacy and a reduced service was provided |
53 | Discontinued procedure | Use if testing was discontinued after initiation due to specimen failure or contamination |
56 | Preoperative diagnostic test | Use when the laboratory test is billed separately from a facility charge that provided the specimen |
62 | Two surgeons | Not typically applicable to lab test; include only if a surgical procedure associated with specimen collection involved two surgeons and payor requires modifier for global billing |
78 | Return to the operating room for a related procedure | Not typical for the lab test itself; could apply to associated surgical billing if reoperation occurs related to specimen collection |
80 | Assistant surgeon | Not applicable to laboratory billing; used on associated surgical CPTs when an assistant surgeon participated |
82 | Assistant surgeon (when qualified resident surgeon not available) | Not applicable to lab billing; used on related surgical services when appropriate |
AS | Physician assistant, nurse practitioner, or clinical nurse specialist services | Use on facility or professional claims when an advanced practitioner performed specimen collection or ordered the test and payor requires this modifier |
QK | Medical direction of two, three, or four concurrent anesthesia procedures | Not applicable to this lab test; included if anesthesia services are billed in the same episode and require modifier reporting |
QX | CRNA service furnished under the direction of an anesthesiologist | Not applicable to the lab test; for associated anesthesia billing only |
