Specialized OB/GYN Billing & RCM

OB/GYN billing services span two distinct practice lines — obstetrics with its global maternity package complexity, and gynecology with its surgical coding demands — and each requires billing discipline that most generalist teams don’t have the depth to handle consistently.

In OB/GYN, the global maternity package is where most billing errors begin — and where mid-pregnancy insurance changes make things worse.

The global obstetric package bundles antepartum care (at least 13 visits), delivery, and routine postpartum care into a single CPT code: 59400 for vaginal delivery including antepartum and postpartum, 59510 for cesarean delivery with the same inclusions, 59610 for VBAC attempt. When a patient delivers at a different practice than the one providing antepartum care, the package must be split — antepartum-only codes (59425 for 4–6 visits, 59426 for 7+ visits) are billed by the antepartum provider, and the delivery code goes to the delivering provider. When a patient switches insurance mid-pregnancy, the package must be split between the old and new payer — one of the most administratively intensive scenarios in healthcare billing. Our full RCM services include OB/GYN-specific billing infrastructure for all of it.

Global Maternity Package Billing

The global package (59400, 59510, 59610) assumes a complete, uncomplicated pregnancy managed by a single practice. Every variation from that model requires split billing. Postpartum-only care (59430) applies when a patient delivers elsewhere and returns to your practice for the 6-week visit. High-risk antepartum services — additional ultrasounds, fetal monitoring, 17P injections — may be billed separately from the global package when they exceed the standard antepartum care included in the bundle. Practices that don't track global package exceptions systematically lose revenue on every complicated pregnancy.

Gynecological Surgery Coding

GYN surgery spans from hysterectomy (58150 abdominal total, 58260–58294 vaginal variants) to laparoscopic procedures (58660–58673) to office-based colposcopy (57452–57461) and LEEP (57460–57461). Each procedure carries a global period — major GYN surgery at 90 days — and the same modifier framework as other surgical specialties applies (-58, -78, -79, -24). In-office GYN procedures also generate same-day E/M billing opportunities with modifier -25 when the encounter includes separately documented medical decision-making beyond the procedure itself.

LARC and Contraceptive Device Billing

Long-acting reversible contraceptives represent a significant billing opportunity when billed correctly. The device is billed by J-code (J7300 for Paragard IUD; J7301 for Skyla/Kyleena; J7307 for Nexplanon implant) and the insertion procedure is billed separately (58300 for IUD insertion; 11981 for implant insertion). Payers vary widely in their coverage of LARC devices — some cover device plus insertion, some cover insertion only, some require step therapy documentation. Bundling the device into the insertion code — or vice versa — is both a revenue loss and a coding error.

Ultrasound Billing Documentation

OB/GYN practices perform high volumes of ultrasound — from the first-trimester dating scan (76801) to anatomic surveys (76805) to third-trimester growth scans (76816). Each requires documentation of the specific images obtained, fetal measurements, and clinical indication. Biophysical profiles (76818, 76819), non-stress tests, and fetal monitoring each have their own codes and documentation requirements. Practices that use template-based ultrasound reports without confirming that all required elements are documented generate consistent partial payment or denial on their imaging revenue.

Happy Billing Benchmarks for OB/GYN:

98%+ First-Pass Clean Claim Rate

OB/GYN claims fail most often on global package split errors, LARC device-insertion bundling, and missing ultrasound documentation elements. We catch all three before the claim leaves our system.

Global Package Tracking Across the Entire Pregnancy

We track every antepartum patient’s insurance status and care provider assignments from the first visit to delivery — flagging package splits, mid-pregnancy insurance changes, and delivery attribution issues before they become billing problems.

LARC J-Code and Insertion Code Accuracy

Every LARC claim is reviewed for correct device J-code, payer-specific coverage confirmation, and separate insertion code with the appropriate documentation. Device and insertion revenue are both captured on every qualifying encounter.

A/R Under 35 Days

OB/GYN practices manage a mix of global package payments (collected after delivery), same-day GYN procedure billing, and monthly antepartum billing. Our 24/7 team tracks all three simultaneously.

Our Specialized Process

Global Package Lifecycle Management

We track every obstetric patient from first visit to postpartum discharge, flagging insurance changes, provider transfers, and delivery attribution issues throughout the pregnancy. Global package splits are handled correctly every time — no revenue lost to billing the wrong code after an insurance change.

GYN Surgery and Modifier Compliance

We review every GYN surgical claim for correct procedure code selection, global period status, and modifier application — including same-day E/M modifier -25 for office procedures. Every GYN procedure generates the full reimbursement it warrants.

LARC Device and Insertion Billing

We confirm LARC device coverage by payer, select the correct J-code and insertion CPT, and handle documentation of medical necessity when required. Device cost and insertion revenue are both captured — separately and correctly.

Ultrasound Documentation Review

Every ultrasound claim is reviewed for required image documentation, fetal measurement reporting, and clinical indication before submission. No ultrasound revenue is lost to a partial payment for incomplete documentation.

Seamless Workflow for Women’s Health.

We work inside the EHRs that obstetric and gynecologic practices rely on most — without migration or disruption. Our team is expert-certified in:

Frequently Asked Questins

How do you handle billing when a patient switches insurance during pregnancy?

When insurance changes mid-pregnancy, the global package must be split by the old and new payer. Services provided under the original insurance are billed to that payer — often antepartum visits using codes 59425 or 59426. Services after the insurance change, including delivery, are billed to the new payer. This requires tracking the exact date of coverage change and confirming that both payers receive a correctly scoped claim. We manage this as part of our standard OB patient tracking workflow.
