Direct Answer
OB/GYN billing is split between two distinct service lines with very different billing models: obstetrics uses a global package model where antepartum, delivery, and postpartum care are bundled into a single global payment, while gynecology uses standard surgical and E&M billing for individual procedures and visits. The most complex OB billing scenario is the split global package — when care is divided among multiple providers (the delivering physician did not provide all antepartum visits) — which requires unbundling the global and billing individual antepartum and delivery components separately.

Global Obstetric Package 59400-59430
The global obstetric package bundles all routine antepartum, delivery, and postpartum care into a single payment: Global package codes: 59400 — routine obstetric care including antepartum care, vaginal delivery (with or without episiotomy, and/or forceps), and postpartum care; 59510 — routine obstetric care including antepartum care, cesarean delivery, and postpartum care; 59610 — routine obstetric care including antepartum care, vaginal delivery (with or without episiotomy, and/or forceps) after previous cesarean delivery, and postpartum care; 59618 — routine obstetric care including antepartum care, cesarean delivery following attempted vaginal delivery after previous cesarean delivery, and postpartum care; What the global package includes: antepartum care — the first OB visit (initial comprehensive history and physical); subsequent antepartum visits (typically monthly through 28 weeks, every 2 weeks 28-36 weeks, then weekly 36-40 weeks); standard antepartum labs ordered and ordered; fetal monitoring and basic ultrasounds (limited ultrasound at antepartum visits may be included); delivery — the delivery service itself (vaginal or cesarean); labor management and monitoring; regional anesthesia services are billed by the anesthesiologist separately; postpartum care — the inpatient postpartum visit(s); the outpartum postpartum visit (typically at 6 weeks); What is NOT included in the global package and is separately billable: high-risk pregnancy services: 59050/59051 — fetal monitoring during labor; 76801-76816 — detailed obstetric ultrasound beyond basic; 76820 — Doppler velocimetry; 76821 — middle cerebral artery Doppler; 59070 — transabdominal amnioinfusion; 59012 — cordocentesis; 59015 — chorionic villus sampling; 59025 — non-stress test; 59030 — fetal scalp blood sampling; medical complications of pregnancy requiring additional management beyond routine OB care; prenatal labs beyond the standard panel (additional genetic testing, specialized testing); When billing the global package: the global package is typically billed at or around the time of delivery; some payers require the claim to be submitted after the postpartum visit; many practices bill the global code at delivery and then bill the postpartum visit separately — this is a common billing error if the postpartum visit is included in the global.
Delivery Codes and Complications
When the global package cannot be billed (split care, high-risk delivery, complications), individual delivery and antepartum codes apply: Individual delivery codes: 59409 — vaginal delivery only (with or without episiotomy and/or forceps); 59412 — external cephalic version, with or without tocolysis; 59414 — delivery of placenta (separate procedure); 59515 — cesarean delivery only; 59620 — attempted vaginal delivery following previous cesarean delivery; 59622 — cesarean delivery following unsuccessful attempt at vaginal delivery after previous cesarean; Vaginal delivery add-on codes: 59300 — episiotomy; not separately billable when included in global or delivery code — the delivery code includes episiotomy; 59320 — cerclage of cervix, during pregnancy; Cesarean-related codes: 59300 and 59001 are sometimes used for associated procedures; Delivery complications: 59870 — uterine evacuation and curettage for hydatidiform mole; 59100 — hysterotomy, abdominal (e.g., for hydatidiform mole, abortion); 59120 — surgical treatment of ectopic pregnancy, tubal or ovarian, requiring salpingectomy and/or oophorectomy; 59121 — without salpingectomy and/or oophorectomy; 59130 — surgical treatment of ectopic pregnancy, abdominal; 59135 — interstitial, uterine, requiring total hysterectomy; 59136 — interstitial, uterine, with partial resection of uterus; 59150 — surgical treatment of ectopic pregnancy, laparoscopic; 59151 — with salpingectomy and/or oophorectomy; Postpartum hemorrhage: 59160 — curettage, postpartum; labor induction and augmentation: 59200 — insertion of cervical dilator (separate procedure); 99150 — labor management by obstetrician when induction ordered by a different physician; 59025 — non-stress test during labor.
Split Global Package Billing
When multiple physicians share the obstetric care (different physician delivers than provided antepartum care), the global package must be split: When split billing applies: the patient transfers care during pregnancy (moves, changes practices, transfers to high-risk OB); the on-call physician delivers the baby for a practice partner; the patient is seen by different physicians in a group practice for different antepartum visits; one practice provides all antepartum care and another provides delivery; Individual antepartum care codes: 59425 — antepartum care only; 4-6 visits; 59426 — antepartum care only; 7 or more visits; individual antepartum visits (when fewer than 4): billed with E&M codes 99201-99215 (new patient if first antepartum visit with this physician) or 99211-99215 (established); Delivery-only codes: 59409 — vaginal delivery only (no antepartum or postpartum); 59515 — cesarean delivery only; Postpartum care only: 59430 — postpartum care only (separate procedure); Split billing example — practice A provided 8 antepartum visits, practice B delivered the baby: Practice A bills 59426 (antepartum care, 7 or more visits); Practice B bills 59409 (vaginal delivery only) + 59430 (postpartum care); the total payment across both practices should approximate the global package rate; Visit counting for split billing: document the total number of antepartum visits in the medical record; the first comprehensive OB visit (initial H&P) counts as an antepartum visit for split billing purposes; counting includes only face-to-face prenatal care visits — telephone calls, portal messages, and ancillary services do not count as visits.
Gynecology Procedure Billing
The GYN side of OB/GYN uses standard surgical and E&M billing: Hysterectomy codes: 58150 — total abdominal hysterectomy (corpus and cervix), with or without removal of tube(s), with or without removal of ovary(s); 58180 — supracervical abdominal hysterectomy; 58260 — vaginal hysterectomy, for uterus 250g or less; 58262 — vaginal hysterectomy with removal of tube(s) and/or ovary(s); 58550-58554 — laparoscopic hysterectomy (total, supracervical, with/without adnexal removal); Laparoscopic GYN procedures: 49320 — laparoscopy, abdomen, diagnostic (general); 58661 — laparoscopy, surgical; with removal of adnexal structures (partial or total oophorectomy and/or salpingectomy); 58670 — laparoscopy, surgical; with fulguration of oviducts (with or without transection); 58672 — with fulguration of uterine horns (with or without transection); 58679 — unlisted laparoscopy procedure, oviduct, ovary; 58545/58546 — laparoscopy, surgical; myomectomy; Endometrial procedures: 58100 — endometrial sampling (biopsy); 58300 — insertion of IUD; 58301 — removal of IUD; 58558 — hysteroscopy, surgical; with sampling (biopsy) of endometrium and/or polypectomy; 58561 — hysteroscopy with removal of leiomyomata; 58562 — with removal of impacted foreign body; 58563 — with endometrial ablation; Colposcopy: 57452 — colposcopy of the cervix; 57454 — with biopsy(s) of the cervix; 57456 — with endocervical curettage; 57460 — with loop electrode excision; 57461 — with loop electrode excision and endocervical curettage; Preventive GYN services: G0101 — cervical or vaginal cancer screening; pelvic and clinical breast examination; Q0091 — screening Papanicolaou smear (pap); G0101 and Q0091 together represent the annual GYN preventive exam and pap for Medicare beneficiaries; Medicare covers G0101 annually for high-risk women, every 2 years for average-risk.
OB/GYN Denials and RCM
OB/GYN practices face specific denial patterns in both obstetrics and gynecology: Common OB/GYN denial patterns: global package timing: billing the global package before the postpartum period is complete; some payers reject the global if billed more than a certain number of days before the expected postpartum visit date; split billing errors: billing the full global package (59400) when the delivering physician did not provide all antepartum visits; or failing to bill 59426 when 7+ antepartum visits were provided; high-risk services not documented: billing additional high-risk pregnancy services (non-stress tests, detailed ultrasounds) without documented clinical indication; these are separately billable only when medically necessary and documented; GYN procedure bundling: billing multiple laparoscopic GYN procedures as separate codes when NCCI bundles them; for complex laparoscopic cases, review NCCI edits before finalizing codes; preventive vs. problem-focused visit billing: billing a preventive E&M (99385-99397) and a problem-focused E&M (99213-99215) for the same visit when a medical problem is identified during the annual exam requires Modifier 25 on the problem-focused E&M; OB/GYN RCM best practices: global package tracking: maintain a pregnancy tracking system that records each patient's antepartum visit count, expected delivery date, and delivering provider; this enables accurate global vs. split billing determination at delivery time; postpartum visit workflow: ensure the postpartum visit (typically 4-6 weeks after delivery) is scheduled and documented; the global package includes this visit — failure to see the patient for postpartum care does not change the global billing, but is a quality standard.
FAQ
How are high-risk pregnancy services billed in addition to the global obstetric package?
High-risk obstetric services are separately billable in addition to the global package when they are medically necessary and documented. These services are not included in the routine antepartum care component of the global: Detailed obstetric ultrasound: 76801 — ultrasound, pregnant uterus, fetal and maternal evaluation; first trimester (less than 14 weeks 0 days), transabdominal approach; single or first gestation; 76802 — each additional gestation; 76805 — greater than or equal to 14 weeks 0 days; 76810 — each additional gestation; 76811 — detailed fetal anatomic examination; includes structures of head and neck, chest, abdomen, extremities, and spine; more comprehensive than 76805; 76812 — each additional gestation; 76816 — follow-up or repeat ultrasound; these codes are separately billable when performed for medical indications (short cervix, fetal growth restriction, anomaly screening, multiple gestation); Non-stress test (NST): 59025 — fetal non-stress test; each NST session is separately billable; NSTs are typically ordered for: post-dates pregnancy; gestational diabetes; hypertensive disorders; decreased fetal movement; fetal growth restriction; multiple gestation; biophysical profile (BPP): 76818 — fetal biophysical profile with non-stress test; 76819 — without non-stress test; BPPs are separately billable and typically follow a failed NST or are used for high-risk management; Cervical length measurement: 76817 — ultrasound, pregnant uterus, transvaginal; separately billable for cervical length monitoring in patients at risk for preterm delivery; Cerclage: 59320 — cerclage of cervix, during pregnancy; separately billable for patients with cervical incompetence or short cervix; Amniocentesis: 59000 — amniocentesis; 76946 — ultrasound guidance for amniocentesis; both codes billable when amniocentesis is performed; indications must be documented (genetic testing, fetal lung maturity, infection); E&M for complications: when a pregnant patient presents with a complication requiring evaluation and management beyond routine antepartum care (hypertensive crisis, preterm labor, bleeding), a separate E&M code (99221-99223 for inpatient admission, or 99212-99215 for office visit) can be billed in addition to the global, with Modifier 25 to indicate the separately identifiable service.
What is the correct billing approach when an OB/GYN performs both a preventive annual exam and addresses a medical problem at the same visit?
The annual GYN preventive exam and a problem-focused visit can both be billed on the same date when the problem is significant and separately identifiable from the preventive service: The dual billing rule: when a physician performs a preventive medicine service and also evaluates or treats a new or existing problem that requires additional work beyond the preventive service, both the preventive code and an E&M code may be billed; the E&M code requires Modifier 25 (significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service); Preventive visit codes: 99384-99387 — new patient preventive medicine services; 99394-99397 — established patient preventive medicine services; selected by patient age; for Medicare: G0101 + Q0091 for pelvic exam and pap; 99385/99395 — ages 18-39; 99386/99396 — ages 40-64; 99387/99397 — 65 and older; What constitutes a separately billable problem: the problem must require a level of work above and beyond what is included in the preventive exam; the physician's documentation must include: a problem-focused history for the additional condition; an assessment and plan for the problem; a risk level that supports the E&M level billed; examples of separately identifiable problems: new diagnosis of an abnormal pap requiring colposcopy discussion and planning; assessment of abnormal uterine bleeding requiring workup; management of a new or worsening GYN condition (fibroid symptoms, endometriosis flare); Documentation requirement: two distinct sections in the note: one for the preventive exam (appropriate age-specific content); one for the problem (separate history, assessment, and plan); if the two services are documented together without clear distinction, the payer may deny the additional E&M; the Modifier 25 signals to the payer that both services were legitimately provided; Medicare note: Medicare and many Medicare Advantage plans cover the annual wellness visit (AWV, G0438/G0439) separately from the preventive gynecologic exam (G0101/Q0091); a patient may receive both on the same date if medically appropriate, but billing practices for AWV + GYN exam + problem visit on the same date should be reviewed carefully by payer.
