CPT 59426: Mini-Global Antepartum Service (7+ Visits)
CPT code 59426 denotes a mini-global obstetric service covering providers who deliver seven or more antepartum visits but do not furnish the full global maternity package. The code is used in transfer scenarios — either when the patient leaves the practice before delivery or when a clinician accepts a patient late in pregnancy and the payer disallows global maternity reporting. Nationally, 59426 matters because it clarifies billing for partial antepartum care and prevents miscoding of global obstetric services, which affects claims processing and payment consistency.
This analysis covers major national payers: Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find an overview of the code's clinical context, typical use cases, and how it relates to adjacent obstetric codes. The publication provides benchmarks for utilization and billing patterns where available, highlights relevant payer policy considerations, and summarizes operational implications for providers and billing staff.
The content is intended for clinicians, billing professionals, and policy analysts seeking concise guidance on when 59426 is appropriate, how it differs from related antepartum and postpartum codes, and what to expect from payer coverage and reporting practices. Data not available in the input will be noted explicitly in detailed sections.

Typical Site of Service: Office or outpatient obstetrics clinic; delivery site when provider performs delivery but is reporting a non-global antepartum component
National Reimbursement Benchmarks
Nationwide, Medicare’s mean rate of $1,070.10 sits very close to BUCA’s average commercial mean of $1,118.40, with BUCA about $48.30 higher — a narrow gap that positions Medicare near the middle of the national commercial range for CPT 59426. That proximity suggests commercial plans on average reimburse only modestly above Medicare for this service, while some commercial payers extend substantially higher means (e.g., Cigna and UnitedHealth Group).
Dispersion across payers varies: compute P75−P25 ranges to compare variability. Blue Cross Blue Shield shows a range of $480.50, Aetna $605.10, Cigna $876.70, UnitedHealth Group $825.10, and BUCA $578.00; Medicare’s interquartile spread is $92.00. Medicare is the tightest by far, while Cigna is the widest, with UnitedHealth Group also showing substantial dispersion. These differences highlight where commercial reimbursements are most variable versus Medicare’s consistency.
