Direct Answer
OB/GYN billing is divided into two distinct segments with different billing logic. Obstetric billing centers on the global OB package — a single code that bundles all antepartum, delivery, and postpartum care. When care is split among providers or when additional services exceed what is included in the global package, the global code must be broken apart into its component codes. GYN billing follows standard surgical coding rules with specific codes for the major procedure categories: hysterectomy, laparoscopy, endoscopy, and office procedures. The most complex OB billing scenarios arise when: multiple providers share obstetric care; the patient delivers early (before completing all antepartum visits); hospitalization during pregnancy requires services outside the global package; or a planned vaginal delivery converts to cesarean section.

Global Obstetric Package
The global obstetric package is a unique billing construct that bundles prenatal, delivery, and postpartum care into a single reimbursement: Global vaginal delivery package: 59400 — Routine obstetric care including antepartum care, vaginal delivery (with or without episiotomy, and/or forceps) and postpartum care; this single code covers the entire episode of care from the first prenatal visit through the postpartum visit; What is included in the global OB package (59400): antepartum care: initial and subsequent prenatal visits (typically 13 visits for standard-risk pregnancy — the first visit, 1 visit per month through 28 weeks, biweekly through 36 weeks, then weekly until delivery); vaginal delivery including labor management, episiotomy if performed, and delivery; postpartum care: one postpartum visit (typically 4–6 weeks after delivery); What is NOT included in the global OB package: additional E&M visits beyond the standard antepartum visit schedule; visits for complications unrelated to the pregnancy; ultrasounds, non-stress tests (NST), and other antepartum surveillance testing; lab work; hospital admissions for conditions other than labor (e.g., preterm labor observation, hyperemesis, preeclampsia management before the delivery admission); Cesarean delivery package: 59510 — Routine obstetric care including antepartum care, cesarean delivery, and postpartum care; 59514 — Cesarean delivery only; 59515 — Cesarean delivery including postpartum care; 59525 — Subtotal or total hysterectomy after cesarean delivery (add-on); Antepartum-only codes (when another provider delivers): 59425 — Antepartum care only; 4–6 visits; 59426 — Antepartum care only; 7 or more visits; these codes are used when the antepartum provider does not deliver the patient (care transferred to another provider, or patient moves); Delivery-only codes: 59409 — Vaginal delivery only (with or without episiotomy, and/or forceps); 59612 — Vaginal delivery only, after previous cesarean delivery; 59620 — Attempted vaginal delivery after previous cesarean delivery resulting in cesarean delivery; Postpartum care only: 59430 — Postpartum care only (separate procedure).
Delivery and Postpartum Codes
When the global package is broken into components, each element must be billed separately: Breaking apart the global package: the global package is broken apart when: the delivering physician did not provide any antepartum care; different physicians provided different components of care; the patient had fewer than 4 antepartum visits before delivery (use delivery-only code 59409); Vaginal birth after cesarean (VBAC): 59610 — Routine obstetric care including antepartum care, vaginal delivery after previous cesarean delivery, and postpartum care; 59612 — Vaginal delivery only, after previous cesarean delivery; 59614 — Postpartum care only, after previous cesarean delivery; Trial of labor resulting in cesarean (TOLAC to C-section): 59618 — Routine obstetric care including antepartum care, attempted vaginal delivery after previous cesarean delivery, and postpartum care (when care results in C-section); 59620 — Attempted vaginal delivery after previous C-section resulting in cesarean delivery; Vaginal delivery with forceps/vacuum: no separate code — forceps or vacuum-assisted delivery is included in the vaginal delivery codes (59400, 59409, 59410); Induction of labor: there is no separate CPT code for induction of labor — induction is included in the delivery code; if induction is unsuccessful and the patient is discharged and returns for delivery, the delivery code still encompasses the induction attempt; Episiotomy: included in vaginal delivery codes — do not bill separately; Repair of obstetric lacerations: 59300 — Episiotomy or vaginal repair, separate procedure; 59350 — Repair of ruptured uterus (separate from delivery); Perineal laceration repair is generally included in the global delivery code for routine lacerations (1st and 2nd degree); 3rd and 4th degree laceration repair may be separately reportable depending on the extent and complexity.
High-Risk Obstetric Billing
High-risk obstetric management generates additional billable services beyond the global package: Services separately billable beyond the global OB package: Antepartum surveillance: non-stress test (NST): 59025 — Fetal non-stress test; 59020 — Fetal contraction stress test; biophysical profile (BPP): 76818 — Fetal biophysical profile with non-stress test; 76819 — Fetal biophysical profile without non-stress test; Obstetric ultrasound: 76801 — Ultrasound, pregnant uterus, less than 14 weeks 0 days, transabdominal; 76802 — Add-on, each additional gestation; 76805 — Ultrasound, pregnant uterus, 14 weeks 0 days to 20 weeks 6 days; 76811 — Detailed fetal anatomic examination; 76815 — Limited obstetric ultrasound; 76816 — Follow-up or repeat obstetric ultrasound; 76817 — Transvaginal obstetric ultrasound; Cervical length measurement: separately billable as an ultrasound service; Amniocentesis: 59000 — Amniocentesis, diagnostic; 59001 — Therapeutic; Chorionic villus sampling: 59015; Fetal monitoring: 59050 — Fetal monitoring during labor by consulting physician (with written report); 59051 — Interpretation only; Antepartum hospitalization: when a patient is hospitalized during pregnancy for a complication (preterm labor monitoring, preeclampsia management, PPROM monitoring before labor begins), the hospital care is billed separately from the global OB package: use standard E&M codes (99221-99233) for the inpatient hospital care; the global OB package continues to include the antepartum visits in the office; Maternal-fetal medicine (MFM) consultation: MFM specialists bill consultation and co-management services using standard E&M codes (99202-99215 for outpatient, 99221-99233 for inpatient) — not the global OB package codes, as MFM typically does not deliver the patient.
GYN Procedure Codes
GYN surgery covers a broad range of procedures organized by approach and extent: Hysterectomy codes organized by approach and uterine weight: Abdominal hysterectomy: 58150 — Total abdominal hysterectomy (corpus and cervix), with or without removal of tube(s), with or without removal of ovary(s); 58152 — With colpo-urethrocystopexy; 58180 — Supracervical abdominal hysterectomy; Vaginal hysterectomy: 58260 — Vaginal hysterectomy, for uterus 250 grams or less; 58262 — With removal of tube(s), and/or ovary(s); 58263 — With removal of tube(s) and/or ovary(s), with repair of enterocele; 58267 — With colpoplasty; Laparoscopic hysterectomy: 58541 — Laparoscopic supracervical hysterectomy, uterus 250 grams or less; 58542 — Uterus greater than 250 grams; 58543 — Total laparoscopic hysterectomy, uterus 250 grams or less; 58544 — Uterus greater than 250 grams; 58550 — Laparoscopic-assisted vaginal hysterectomy (LAVH); 58552 — LAVH with removal of tube(s) and/or ovary(s); 58553 — LAVH, uterus greater than 250 grams; 58554 — LAVH greater than 250 grams with tube/ovary removal; Diagnostic and operative laparoscopy: 49320 — Laparoscopy, abdomen, peritoneum, and omentum, diagnostic; 58660 — Laparoscopy, surgical, with lysis of adhesions; 58661 — With removal of adnexal structures; 58662 — With fulguration or excision of lesions; 58670 — With fulguration of oviducts (with or without transaction); 58671 — With occlusion of oviducts by device (e.g., band, clip, or Falope ring); Hysteroscopy: 58555 — Diagnostic hysteroscopy with or without endometrial biopsy; 58558 — Hysteroscopy with sampling (biopsy) of endometrium and/or polypectomy; 58560 — With division or resection of intrauterine septum; 58561 — With removal of leiomyomata; 58562 — With removal of impacted foreign body; 58563 — With endometrial ablation.
OB/GYN RCM
OB/GYN revenue cycle management has specific challenges related to the global OB package, split-care coordination, and surgical prior authorization: Global OB package charge timing: the global OB package code (59400, 59510) should be billed after delivery — billing the global code early in the pregnancy ties up the claim; some practices bill the antepartum component during pregnancy using a "dummy" claim that is replaced at delivery; the most common practice is to hold the global OB charge until after delivery and the postpartum visit; Split-care documentation: when obstetric care is split between providers (e.g., in a group practice where patients see multiple physicians during antepartum care), clear documentation of which provider delivered each service is essential for accurate billing of antepartum-only codes and global package attribution; in group practice OB billing, the delivering physician's NPI determines which global code is billed; Verifying OB coverage at onset of care: verify the patient's maternity benefit at the first prenatal visit, not at delivery; key items to verify: is maternity care covered? what is the global maternity deductible (some plans have separate OB deductibles)? what is the copay or coinsurance for the global package? are there visit limits or delivery limits? Medicaid OB billing: Medicaid covers OB care but reimbursement rates for the global package vary significantly by state; some state Medicaid programs require prior authorization for scheduled cesarean sections; verify state-specific Medicaid billing rules for your jurisdiction; Surgical prior authorization for GYN: hysterectomy and major GYN surgery routinely require prior authorization; the authorization must specify the surgical approach (abdominal vs. laparoscopic) and the specific procedure codes; authorization for hysterectomy does not automatically authorize concurrent procedures (oophorectomy, cystoscopy); Modifier 22 for unusually complex GYN cases: when a GYN surgical procedure is significantly more complex than typical (dense pelvic adhesions, prior surgeries, anatomic anomalies), Modifier 22 (increased procedural services) can be appended with documentation of the increased complexity and the additional time and effort required.
FAQ
How should a group OB practice bill when multiple physicians provide antepartum care but one delivers the patient?
Group OB practices are one of the most common scenarios requiring careful global package allocation. The standard approach in a group practice where patients see multiple physicians for antepartum care but one physician delivers: Option 1 — Bill the global package under the delivering physician: the delivering physician bills the complete global OB package (59400 for vaginal or 59510 for C-section) under his or her NPI; the global package payment is credited to the delivering physician; antepartum visits provided by other physicians in the group are included in the global payment — no separate billing for individual antepartum visits; this approach is the most administratively straightforward and is common in group practices that share call and delivery responsibilities; Option 2 — Bill individual antepartum visits plus delivery-only: each physician bills separately for their antepartum visits using individual E&M codes during the pregnancy; the delivering physician bills the delivery-only code (59409 for vaginal or 59514 for C-section); this approach is more complex but may be appropriate when physicians are in separate groups but share call coverage; Important compliance consideration for Option 2: if individual antepartum E&M visits are billed separately during pregnancy AND a global package is later billed at delivery, the payer may deny the global code as a duplicate claim; practices using Option 2 must use the delivery-only codes (59409, 59514), NOT the global package codes (59400, 59510); Antepartum visit count and global package eligibility: if the delivering physician provided the majority of antepartum care (7 or more visits), the global code is appropriate; if fewer than 4 antepartum visits were provided before delivery (premature delivery, late transfer of care), use the delivery-only codes; 4–6 antepartum visits by the delivering physician plus delivery: use the global code — the payment includes the global package even with fewer than the standard visit count.
What GYN procedures require prior authorization and how should the practice manage the authorization process to avoid denials?
GYN surgical prior authorization requirements vary by payer, but major procedures routinely requiring PA from most commercial payers include: Hysterectomy (all approaches): commercial payers almost universally require PA for hysterectomy; the authorization process typically requires documentation of conservative treatment failure (medical management, endometrial ablation, or other less invasive options) before authorizing hysterectomy for benign indications; for malignant indications (uterine cancer, cervical cancer), documentation of the cancer diagnosis expedites PA; the PA request must specify the surgical approach and the exact CPT codes planned; Endometrial ablation (58563): some payers require PA; documentation of abnormal uterine bleeding diagnosis and conservative management is typically required; Laparoscopic procedures: diagnostic laparoscopy (49320) often does not require PA; operative laparoscopy (58660-58671) typically requires PA based on the proposed procedures; Hysteroscopic procedures: hysteroscopic polypectomy, septum resection, and myomectomy (58558-58561) require PA from most commercial payers; routine diagnostic hysteroscopy may not require PA; Documentation required for GYN PA requests: history of presenting condition with onset and duration; diagnosis codes and supporting documentation; prior conservative treatment and response; proposed CPT code(s) with description; clinical notes supporting medical necessity; For laparoscopy for endometriosis: documentation of symptoms, failed medical management, and imaging findings supporting diagnosis; Authorization number management: the authorization number must be included on the claim for all authorized procedures; if a concurrent procedure was performed that was not on the original authorization, bill it separately with documentation of medical necessity; contact the payer's provider line if a concurrent finding requires unplanned additional procedures during surgery — same-day authorization requests are possible in some cases.
