1. An OB performs a successful VBAC delivery and provides all postpartum care. A different physician had provided all antepartum care. Which CPT® code does the delivering OB report?
   Answer: 59614 CPT® 59614 describes vaginal delivery after previous cesarean delivery with postpartum care — the correct code for the two-component package (VBAC delivery + postpartum care) when the delivering physician did not provide antepartum care. Code 59612 describes VBAC delivery only, without postpartum care; the delivering OB here provides postpartum care as well, requiring 59614. Code 59610 is the full global VBAC package including antepartum care; this physician did not provide antepartum care. Code 59622 describes failed VBAC cesarean delivery with postpartum care; the VBAC is successful (vaginal delivery). Prior cesarean history and delivery method together determine the VBAC code series (59612/59614/59610), distinct from the standard vaginal delivery series (59409/59410/59400).
2. A single OB provides all antepartum care, successful trial of labor after cesarean (VBAC) delivery, and postpartum care for a patient with a prior cesarean. Which CPT® code reports the complete global obstetric package?
   Answer: 59610 CPT® 59610 describes routine obstetric care including antepartum care, vaginal delivery after previous cesarean delivery (VBAC), and postpartum care — the global package for a successful trial of labor after cesarean that results in vaginal birth when the same physician provides all three components. Code 59400 is the global package for vaginal delivery in a patient without a prior cesarean history; prior cesarean status triggers the VBAC-specific codes. Code 59618 is the global package for an attempted VBAC that ultimately requires cesarean delivery (failed TOLAC); this patient delivered vaginally (successful VBAC), so 59618 does not apply. Code 59612 describes VBAC delivery only, without antepartum or postpartum care. Prior cesarean history always upgrades the delivery code from the standard vaginal delivery codes to the VBAC series.
3. A patient at 34 weeks gestation presents with new-onset hypertension (BP 148/94). No proteinuria is detected. She has no prior history of hypertension. Which ICD-10-CM code is assigned for this diagnosis?
   Answer: O13.3 ICD-10-CM code O13.3 describes gestational (pregnancy-induced) hypertension without significant proteinuria, third trimester — the correct code when pregnancy-induced hypertension develops in the third trimester (28 weeks through delivery) without the proteinuria that would indicate preeclampsia. At 34 weeks, this patient is in the third trimester; the trimester-specific code (O13.3) is required rather than the unspecified trimester code O13.9. Code O13.9 describes gestational hypertension, unspecified trimester — reportable only when the trimester cannot be determined from documentation; when the gestational age is documented, the trimester-specific code takes precedence. Code O10.02 describes pre-existing essential hypertension complicating pregnancy; the patient has no prior history of hypertension, confirming this is a new, pregnancy-induced condition. Code O14.00 describes mild to moderate preeclampsia, which requires the presence of significant proteinuria or organ dysfunction; no proteinuria is detected here.
4. An OB places a vaginal cervical cerclage at 17 weeks for cervical insufficiency. No tocolytic therapy is administered. Which CPT® code is reported?
   Answer: 59320 CPT® 59320 describes cerclage of the cervix during pregnancy, vaginal — the correct code for a cervical cerclage placed through the vaginal route during pregnancy to prevent preterm birth from cervical insufficiency. Code 57700 describes cerclage of the uterine cervix for a non-obstetric indication (e.g., cervical incompetence correction outside of pregnancy); this patient is at 17 weeks gestation, making the procedure obstetric. Code 59325 describes vaginal cerclage during pregnancy with tocolysis; no tocolytic therapy was administered here, making 59320 (without tocolysis) correct rather than 59325. Code 59326 describes cerclage of the cervix during pregnancy via the abdominal approach; the approach here is vaginal. The presence or absence of tocolysis differentiates 59320 from 59325.
5. A covering OB performs a vaginal delivery and provides postpartum care. The patient's regular OB had provided all antepartum care. Which CPT® code does the delivering OB report?
   Answer: 59410 CPT® 59410 describes vaginal delivery with postpartum care — the correct code for the two-component package (delivery + postpartum) when a physician performs the vaginal delivery and provides postpartum care but did not provide antepartum care. Code 59409 describes vaginal delivery only, without postpartum care; the OB here also provides postpartum care, requiring 59410 rather than 59409 alone. Code 59400 is the full global package including antepartum care; this physician did not provide antepartum care, disqualifying 59400. Code 59425 describes antepartum care only (4-6 visits). When two of the three global package components are provided (delivery + postpartum), 59410 is used rather than reporting 59409 and 59430 separately.
6. A patient with gestational diabetes controlled by insulin is seen at 30 weeks gestation. No pre-existing diabetes is documented. Which ICD-10-CM code is assigned for this diagnosis?
   Answer: O24.414 ICD-10-CM code O24.414 describes gestational diabetes mellitus in pregnancy, insulin controlled — the correct code when gestational diabetes (not pre-existing DM) requires insulin therapy for glycemic management during the pregnancy. Code E11.9 describes Type 2 diabetes mellitus without complication; gestational diabetes is coded from the O24 category during pregnancy, not from the E10-E13 diabetes categories. Code O24.410 describes gestational diabetes mellitus controlled by diet only; this patient requires insulin, not just dietary management. Code O24.419 describes gestational diabetes in pregnancy with unspecified glycemic control; the documentation specifies insulin-controlled management, making the more specific O24.414 correct. Gestational diabetes codes are differentiated by management type: diet-controlled (O24.410), oral hypoglycemic agent (O24.415), or insulin-controlled (O24.414).
7. A patient presents in active labor at 39 weeks with a spontaneous, uncomplicated vaginal delivery, cephalic presentation, and delivery of a single live infant. No complications are documented. Which ICD-10-CM code is assigned as the principal diagnosis for this delivery encounter?
   Answer: O80 ICD-10-CM code O80 describes an encounter for full-term uncomplicated delivery — the correct principal diagnosis for a delivery that is entirely normal, with spontaneous onset, cephalic presentation, single live birth, and no complications. O80 is used only when all conditions are met: full-term gestation, single live birth, spontaneous onset, vertex presentation, and no complications whatsoever. Code Z34.40 describes supervision of normal pregnancy, unspecified (used for antepartum encounters, not the delivery admission). Code O70.0 describes first-degree perineal laceration, a complication that is not present here. Code Z37.0 describes the outcome of delivery as a single liveborn infant — this is always an additional (secondary) code required alongside the delivery principal diagnosis, but it cannot serve as the principal diagnosis itself. When O80 is assigned, no other complication code may be sequenced on the same claim.
8. An OB provides 9 antepartum visits then transfers the patient to another physician at 36 weeks for the delivery and postpartum care. Which CPT® code does the transferring OB report for the antepartum care rendered?
   Answer: 59426 CPT® 59426 describes antepartum care only, 7 or more visits — the correct code for the transferring physician who provided 9 antepartum visits but did not perform the delivery or postpartum care. Code 59425 describes antepartum care only for 4 to 6 visits; 9 visits exceed this threshold, requiring the 7-or-more-visit code (59426). Code 59400 is the global package code and requires the physician to have provided all three components — antepartum, delivery, and postpartum — which the transferring OB did not. Code 59430 describes postpartum care only; the transferring OB provided antepartum, not postpartum, care. Visit count (4-6 vs. 7 or more) determines whether 59425 or 59426 is appropriate.
9. A patient's regular OB performed no antepartum care but was present for the delivery; a different covering physician will provide all postpartum care. Which CPT® code does the regular OB report for the postpartum care only?
   Answer: 59430 CPT® 59430 describes postpartum care only — the correct code when a physician provides only the postpartum component of the obstetric episode, having not performed the delivery or provided antepartum care. When care is split between providers, each provider reports only the component(s) of care actually rendered. Code 59425 describes antepartum care only (4-6 visits); this physician is providing postpartum, not antepartum, care. Code 59400 is the global package requiring all three components; this physician provides only postpartum care. Code 59426 describes antepartum care only (7 or more visits). Code 59430 is the designated postpartum-only code regardless of the number of postpartum visits provided.
10. A single OB provides all antepartum care for a patient with a prior cesarean. The patient undergoes a trial of labor after cesarean (TOLAC) that fails, resulting in a cesarean delivery. The same OB provides postpartum care. Which CPT® code reports the complete global obstetric package?
    Answer: 59618 CPT® 59618 describes routine obstetric care including antepartum care, cesarean delivery after attempted vaginal delivery after previous cesarean delivery, and postpartum care — the global package for a failed trial of labor after cesarean (TOLAC) resulting in cesarean birth when the same OB provides all three components. Code 59610 is the global package for a successful VBAC (vaginal birth); this patient ultimately delivered by cesarean, making 59610 incorrect. Code 59510 is the global package for primary cesarean delivery without a prior cesarean history or an attempted VBAC; prior cesarean history with an attempted TOLAC requires the 59618 code. Code 59620 describes failed VBAC cesarean delivery only (without antepartum or postpartum care); the OB here provided all three components, requiring the full global package 59618.
11. A single OB provides all antepartum care, performs a primary (first-time) cesarean delivery, and provides postpartum care for the same patient. Which CPT® code reports the complete global obstetric package?
    Answer: 59510 CPT® 59510 describes routine obstetric care including antepartum care, cesarean delivery, and postpartum care — the global package code for a primary (first-time) cesarean delivery when a single physician provides all three components. Code 59400 is the global package for vaginal delivery; a cesarean is performed here, requiring 59510. Code 59515 describes cesarean delivery with postpartum care, but without antepartum care; the physician here also provided antepartum care, requiring the full global package (59510). Code 59514 describes cesarean delivery only (without antepartum or postpartum care). When the same OB provides all three components and the delivery route is cesarean, 59510 is the single code that captures the entire obstetric episode.
12. A covering physician is called in to perform a vaginal delivery for a patient whose regular OB is unavailable. The covering physician provides no antepartum or postpartum care. Which CPT® code does the covering physician report for the delivery only?
    Answer: 59409 CPT® 59409 describes vaginal delivery only (with or without episiotomy and/or forceps) — the correct code when a physician performs only the delivery component without providing antepartum or postpartum care. A covering physician who steps in solely to perform the delivery reports 59409 for that service. Code 59400 is the global package requiring all three components (antepartum, delivery, and postpartum); the covering physician provides only the delivery. Code 59410 describes vaginal delivery with postpartum care; the covering physician provides no postpartum care. Code 59425 describes antepartum care only (4-6 visits); no antepartum care is provided. When a physician delivers a patient whom another physician monitored antenatally and will follow postpartum, 59409 is the appropriate code for the delivering provider.
13. A single OB provides all antepartum care, performs a vaginal delivery with episiotomy, and provides postpartum care for the same patient. Which CPT® code reports the complete global obstetric package?
    Answer: 59400 CPT® 59400 describes routine obstetric care including antepartum care, vaginal delivery (with or without episiotomy and/or forceps), and postpartum care — the global package code reported when a single physician provides all three components: antepartum care, delivery, and postpartum care. Code 59409 describes vaginal delivery only, without antepartum or postpartum care; the physician here also provided antepartum and postpartum care, making 59409 insufficient. Code 59510 describes the global package for cesarean delivery (antepartum + cesarean + postpartum); a vaginal delivery is performed here. Code 59410 describes vaginal delivery with postpartum care but without antepartum care; antepartum care is included here. The global package (59400) encompasses all three service components when provided by the same physician and eliminates the need to report antepartum, delivery, and postpartum codes separately.
14. A surgeon performs an induced abortion at 16 weeks using dilation and evacuation (D&E) for elective termination of a viable pregnancy. Which CPT® code is reported?
    Answer: 59841 CPT® 59841 describes induced abortion by dilation and evacuation (D&E) — the correct code for elective termination of a viable pregnancy using the dilation and evacuation technique, typically performed in the second trimester (13 to 24 weeks). Code 59840 describes induced abortion by dilation and curettage (D&C), which uses suction or sharp curettage and is typically performed in the first trimester; D&E (which includes forceps evacuation of fetal parts) is the technique used here at 16 weeks, requiring 59841. Code 59850 describes induced abortion by intra-amniotic injection (hypertonic saline or urea), a medical induction technique — no injection is performed here. Code 59820 describes treatment of a missed abortion in the first trimester; this is an elective termination of a viable pregnancy (not a missed abortion), and the gestational age is 16 weeks (second trimester). The technique (D&C vs. D&E) determines 59840 vs. 59841.
15. A physician performs an external cephalic version with tocolysis on a patient at 37 weeks to correct a breech presentation. Which CPT® code is reported?
    Answer: 59412 CPT® 59412 describes external cephalic version with or without tocolysis — the correct code for manual transabdominal manipulation of the fetus to convert a malpresentation (breech, transverse) to vertex position, with tocolysis included in the code regardless of whether it is used. Code 59025 describes fetal non-stress testing (electronic fetal monitoring for antepartum surveillance), not a cephalic version procedure. Code 59000 describes diagnostic amniocentesis (needle aspiration of amniotic fluid); no needle is used in an external cephalic version. Code 59325 describes cervical cerclage with tocolysis — a completely different procedure involving placement of a suture around the cervix to prevent preterm birth, not version. CPT® 59412 encompasses the version maneuver with or without tocolytic medication; tocolysis used during version is not separately reportable.
16. A surgeon performs a laparoscopic salpingectomy to treat a right tubal ectopic pregnancy. Which CPT® code is reported?
    Answer: 59151 CPT® 59151 describes laparoscopic treatment of ectopic pregnancy with salpingectomy and/or oophorectomy — the correct code for a laparoscopic procedure in which the affected fallopian tube is removed (salpingectomy) as part of the ectopic pregnancy treatment. Code 59150 describes laparoscopic treatment of ectopic pregnancy without salpingectomy and/or oophorectomy (e.g., salpingostomy, linear incision to remove only the ectopic tissue while preserving the tube); the tube is fully removed here, requiring 59151. Code 59120 describes surgical treatment of ectopic pregnancy with salpingectomy and/or oophorectomy via abdominal or vaginal approach (open technique); the approach here is laparoscopic, not open. Code 59121 describes open treatment without salpingectomy/oophorectomy. Both the approach (laparoscopic vs. open) and the organ status (with vs. without salpingectomy) determine the correct ectopic pregnancy code.
17. A physician performs diagnostic amniocentesis at 16 weeks to obtain amniotic fluid for chromosomal microarray analysis. Which CPT® code is reported?
    Answer: 59000 CPT® 59000 describes amniocentesis, diagnostic — the correct code for transabdominal aspiration of amniotic fluid performed for the purpose of laboratory analysis (genetic, chromosomal, biochemical, or infectious disease testing). Code 59001 describes therapeutic amniocentesis (amnioreduction) to remove large volumes of amniotic fluid for symptom relief in polyhydramnios; the intent here is diagnostic, not therapeutic volume reduction. Code 59025 describes fetal non-stress testing (electronic fetal monitoring), not an amniocentesis. Code 59070 describes transabdominal amnioinfusion (fluid instilled into the amniotic cavity), not fluid withdrawal. Diagnostic versus therapeutic purpose is the determinant separating 59000 from 59001.
18. A physician performs therapeutic amniocentesis (amnioreduction) to remove excess amniotic fluid from a patient with polyhydramnios. Which CPT® code is reported?
    Answer: 59001 CPT® 59001 describes amniocentesis, therapeutic amnioreduction — the correct code for transabdominal aspiration of amniotic fluid performed to reduce uterine volume in cases of polyhydramnios. The intent is therapeutic (volume reduction), not diagnostic. Code 59000 describes diagnostic amniocentesis in which amniotic fluid is obtained for laboratory analysis (chromosomal, biochemical, genetic, or infectious disease testing); the purpose here is therapeutic volume reduction, not diagnosis. Code 59070 describes transabdominal amnioinfusion with ultrasound guidance, in which fluid is introduced into the amniotic cavity (infused, not removed); this procedure removes fluid (amnioreduction), the opposite of infusion. Code 59025 describes a fetal non-stress test, not an amniocentesis. The direction of fluid movement — aspiration/removal (59001) versus infusion (59070) — distinguishes these amniotic fluid codes.
19. An OB provided 5 antepartum visits and then transferred care to another physician who performed the delivery and postpartum care. Which CPT® code does the transferring OB report for the antepartum care?
    Answer: 59425 CPT® 59425 describes antepartum care only, 4 to 6 visits — the correct code for the transferring physician who completed 5 antepartum visits without providing delivery or postpartum services. Code 59426 describes antepartum care only, 7 or more visits; only 5 visits were provided, which falls within the 4-to-6-visit range for 59425. Code 59430 describes postpartum care only; the transferring physician provided antepartum, not postpartum, care. Code 59400 is the global package requiring delivery and postpartum care in addition to antepartum care; the transferring OB did not perform the delivery. For antepartum-only services, visit count determines code selection: 1-3 visits are reported with individual office visit E&M codes; 4-6 visits use 59425; and 7 or more visits use 59426.
20. A physician performs an antepartum fetal non-stress test (NST) to assess fetal well-being without inducing uterine contractions. Which CPT® code is reported?
    Answer: 59025 CPT® 59025 describes fetal non-stress test (NST) — the correct code for electronic fetal heart rate monitoring performed antepartum to assess fetal well-being, without induced uterine contractions. The NST evaluates fetal heart rate accelerations in response to fetal movement. Code 59020 describes the fetal contraction stress test (oxytocin challenge test or CST), in which uterine contractions are deliberately induced with oxytocin or nipple stimulation; no contractions are induced here. Code 59030 describes fetal scalp blood sampling, which involves collecting a blood sample from the fetal scalp during labor. Code 59051 describes interpretation and report of continuous electronic fetal monitoring by a consulting physician during labor; the NST is performed antepartum in the office, not during intrapartum labor monitoring.
