Prenatal care cost per visit, and what changes when you switch doctors

Two pairs of lines are easy to confuse on a statement. Glucose testing appears as 82950, a single glucose measurement after a glucose dose at $4.75, or as 82951, a tolerance test with three specimens at $12.87, which is $8.12 more. Group B strep screening appears as 87081, the culture screen at $6.63, or as 87653, the amplified-probe DNA test at $35.09, which is $28.46 more. The statement should show which method the laboratory billed, since the code follows the method. The venipuncture line, 36415, is $9.34 in the same file and appears when the draw is billed on its own; the guide to what blood work costs explains collection fees and how a hospital outpatient lab bill differs.

For insured readers the question is whether a plan treats these lines as free preventive services. HealthCare.gov says "All Marketplace health plans and many other plans must cover" a list of preventive services for women without a copayment or coinsurance, and its section for pregnant women names gestational diabetes screening "for women 24 weeks pregnant (or later) and those at high risk of developing gestational diabetes," hepatitis B screening "for pregnant women at their first prenatal visit," Rh incompatibility screening "for all pregnant women and follow-up testing for women at higher risk," syphilis screening, and urinary tract or other infection screening. It adds that "Generally, these services are covered at no cost to you when provided by an in-network medical provider," that "Coverage may vary" and that "$0 cost isn't guaranteed in all cases." The pregnant-women section of that list does not name a group B strep test or any genetic screen. A panel code such as 80081 bundles several listed tests with others, so ask the plan how it prices the panel, and see why a preventive visit came with a bill for the triggers that turn a no-cost service into a charge.

Other lines outside the package

The rest of the lines that can appear on a prenatal statement come from three price systems. Procedures are on the physician fee schedule, laboratory tests on the clinical laboratory fee schedule, and drugs on the Part B payment limit file. The table lists them with the system named, because the amounts are not comparable across systems and are never added here.

The federal manual's exclusion list covers ultrasound, amniocentesis and special screening tests for genetic disorders. Michigan's list adds the stress and nonstress tests and chorionic villus sampling. The serum screens and sequence-based screens in the table are the laboratory tests that fall under the genetic screening wording, and their prices range from $15.05 for a single protein to $795.00 for the plasma DNA screen. A single 81507 line at $795.00 is more than eight 99213 visits at $95.55 each. That is a price comparison only: whether any test is wanted is a decision for the patient and the clinician, and this guide takes no position on it.

The Rho(D) immune globulin lines show a different pattern. A drug carries its own HCPCS J-code and its own payment limit, and the fee schedule also has an injection administration code, 96372 at $15.27. The J2790 limit is $82.08 per 300 mcg (1500 IU) and the J2788 limit is $27.65 per 50 mcg, both in the October 2026 file. The file's own note says the presence of a code and its limit "does not indicate whether Medicare covers a drug."

What Medicare's manuals say about split care

The CMS relative value file documentation defines the global period shown for each maternity code: "MMM=Maternity codes; usual global period does not apply." Every code in the first table carries MMM in the October 2026 file. That one definition matters because the national rules for splitting care between physicians are written for other global periods.

Chapter 12 of the Medicare Claims Processing Manual (revision 13753, issued May 7, 2026), section 40.1, sets the scope of its global surgery rules: "The payment rules for surgical procedures apply to codes with entries of 000, 010, 090, and, sometimes, YYY." The MLN Global Surgery booklet (MLN907166, December 2025) says the same: "The global surgical payment rules apply to procedure codes with global surgery indicators 000, 010, 090, and sometimes, YYY." MMM is not on either list. Section 40.2 then says that when physicians agree on a transfer of care within a global period, "the following modifiers are used: '-54' for surgical care only; or '-55' for postoperative management only," and the booklet adds "Use modifier 55 with the CPT procedure code for global periods of 10 or 90 days." Neither document lists 59400, 59425 or 59426, and the booklet does not mention maternity care. The surgical modifiers are therefore written for the surgical global periods, and nothing in those two documents says they apply to a maternity code.

The NCCI Policy Manual (chapter VII, section G, item 4, revision date January 1, 2026) points the other way, in a sentence about bundling: "Maternity procedures are assigned a global period of MMM on the Medicare Physician Fee Schedule Database. Some of these procedures (e.g., Cesarean section) are similar to surgical procedures with a global period of 000, 010, or 090 days. These types of maternity procedures are subject to global surgery and anesthesia rules. The same HCPCS/CPT codes based on these rules are bundled into this subgroup of MMM procedures as are bundled into surgical procedures with a global period of 000, 010, or 090 days." That paragraph concerns which codes are bundled into a delivery. It does not mention a modifier, and the chapter contains no reference to modifier 54, 55 or 56 or to a transfer of care.

Chapter 12 caps a split global surgical package at the single-physician amount, in section 40.1.D: "When more than one physician furnishes services that are included in the global surgical package, the sum of the amount approved for all physicians may not exceed what would have been paid if a single physician provides all services (except where stated policies, e.g., the surgeon performs only the surgery and a physician other than the surgeon provides preoperative and postoperative inpatient care, result in payment that is higher than the global allowed amount)." The sentence sits inside a section whose scope sentence omits MMM, so it cannot be read as a cap on 59425 plus 59426 plus 59410. That is why the worked cases below show the overage as arithmetic and leave the cap question to the plan.

The one maternity rule in the chapter that ties a split to the global amount is section 130.2, on nurse-midwives (effective January 1, 2011): "When a certified nurse-midwife is providing most of the care to a Medicare beneficiary that is part of a global service and a physician also provides a portion of the care for this same global service, the fee paid to the CNM for his or her care is based on the portion of the global fee that would have been paid to the physician for the care provided by the CNM." The manual's example takes a $1,000 global fee, subtracts a $30 physician visit and pays the nurse-midwife the $970.00 remainder at 100 percent of the fee schedule, and it states that "Physicians and certified nurse-midwives use reduced service modifiers to report that they have not provided all the services covered by the global allowance." The dollar figures are the manual's illustration, and the section does not name the modifier.

Section 100.1.6, on teaching physicians, adds one useful sentence: "In order to bill for the global procedures, the teaching physician must be present for the minimum indicated number of visits when such a number is specified in the description of the code." It confirms that the visit counts in the maternity codes come from the code descriptions themselves. What all of this supports is narrow. The pieces of a split pregnancy are billed under their own codes (delivery only, delivery with postpartum care, postpartum only, antepartum only). Whether a particular modifier is required, allowed or refused on 59400 is a question for each office's billing staff and for the plan, and none of these documents answers it.

Michigan Medicaid's rule for a changed doctor

The clearest written rule for a change of obstetrician is in one state's Medicaid manual, and it applies to that program's fee-for-service claims. The billing chapter (Billing and Reimbursement for Professionals, section 6.21, version date October 1, 2026, page 32) says, under the heading "Physician Change During Antepartum Care": "If the beneficiary changes physicians during the antepartum care (other than physicians within the same group), use the appropriate maternity CPT codes and guidelines for the services performed. The global package should not be billed by either physician regardless of the number of antepartum visits provided." A change inside one group does not count, since a group bills as one practice.

Under "Delivery Global Service" on page 31 the same section says: "CPT guidelines for reporting prenatal care and delivery services apply. Bill the global obstetrical package or the antepartum, delivery, and postpartum components as appropriate per Medicaid NCCI guidelines. Delivery is part of the global maternity package and should not be billed separately if the global package is billed. If the beneficiary is seen for fewer than seven antepartum visits, delivery and postpartum care should be billed separately. Use appropriate CPT guidelines. The global maternity package should be billed if the beneficiary is seen for seven or more antepartum visits with delivery and postpartum performed by the same physician or physician group. The provider or group may choose to bill the antepartum, delivery, and postpartum components separately as allowed by Medicaid NCCI editing."

The Practitioner chapter of the same manual and version, section 7, says something different for the same situation: "The global obstetrical package is covered as long as the provider or group has provided seven or more antepartum visits, the delivery, and the postpartum care. If less than seven antepartum visits are provided, report the global package with the modifier for reduced services and indicate the number of antepartum visits on the claim." One chapter says to bill delivery and postpartum care separately below seven visits, and the other says to bill the global package with a reduced-services modifier. Two offices working from the same manual can read it differently, which is the practical reason to ask each office which codes it intends to send.

Section 7.4 of the Practitioner chapter explains the component approach: "If the same physician or group practice does not provide all of the obstetric care, Medicaid covers the portion of the care provided by each provider. Postpartum care or antepartum care is covered separately if provided by a different physician or group than the physician providing the delivery services. To be consistent with some commercial payers and Medicare, the physician or group providing the entire global obstetrical package may choose to report either the entire global package or may report the antepartum care, delivery, and postpartum care separately as each of these services is provided. Combinations of these components must be allowable under Medicaid NCCI editing. Components such as the antepartum care or postpartum care cannot be unbundled into individual visits."

Changing doctors at week 12, 24 or 34

The cases below apply Michigan's rule to the Medicare anchors above. The schedule is invented for the arithmetic: thirteen antepartum visits at weeks 8, 12, 16, 20, 24, 28, 30, 32, 34, 36, 37, 38, 39, then a vaginal delivery at week 40 with postpartum care. The first office keeps the visits up to and including the switch week, and the second office takes the remaining visits, the delivery and the postpartum care. Where an office has three or fewer visits it bills them as office visits, a 99204 first and a 99213 for each later one, which is an assumption about levels. Where it has four to six it bills 59425, and from seven it bills 59426. The second office bills 59410 for the delivery with postpartum care. Michigan's rule keeps both offices from billing 59400.

After week 12. Two visits leave the first office below the antepartum codes, so it sends two office visit claims, $179.97 and $95.55, for $275.52. The second office has 11 antepartum visits plus the delivery and postpartum care, which puts it on 59426 ($1,133.98) and 59410 ($1,092.67), $2,226.65 together. The two offices come to $2,502.17, which is $68.12 above 59400.

After week 24. Five visits put the first office on 59425, $617.53. The second office has 8 visits, so it bills 59426 and 59410 for $2,226.65. The total is $2,844.18, $410.13 above 59400.

After week 34. Nine visits put the first office on 59426, $1,133.98. The second office has 4 visits and bills 59425 and 59410 for $1,710.20. The total is $2,844.18, again $410.13 above 59400.

The week 24 and week 34 totals match because the combination is the same: 59425, 59426 and 59410 each billed once, with the codes assigned to different offices. The same total divides differently. In the week 34 case the first office's claim is $516.45 larger than in the week 24 case and the second office's is $516.45 smaller, the gap between the two antepartum rungs. For the patient the split matters because each claim meets the plan separately. If the two offices differ in network status, or the change crosses a plan year or a change of insurer, the same total produces different cost sharing. The overage above 59400 exists in the fee schedule arithmetic and has no payer behind it unless a plan chooses to pay both offices in full.

A third office changes the delivery side. If the postpartum visit is handled elsewhere, the delivering office bills 59409 ($810.14) and the postpartum office bills 59430 ($277.97), $1,088.11 together, which is $4.56 less than the single 59410 line.

The same splits with a cesarean

A cesarean changes the delivery code and the global comparison and leaves the antepartum rungs alone. The delivering office bills 59515, delivery with postpartum care, and the single-practice comparison is 59510.

The gap to the global code is $45.09 after week 12 and $387.10 after weeks 24 and 34. Each is $23.03 below the vaginal-delivery gap ($68.12 and $410.13), because the cesarean global code, $2,747.83, is valued $313.78 above the vaginal one while the delivery-plus-postpartum code 59515 is $290.75 above 59410. If a different office handles the postpartum visit after a cesarean, 59514 ($934.35) and 59430 ($277.97) come to $1,212.32, which is $171.10 less than 59515. The hospital side of a cesarean is a separate layer, covered in the guide to the hospital birth bill, and anesthesia is a third.

Pregnancies that cross into 2027

Everything above describes the code set that applies to dates of service through December 31, 2026. CMS's CY2027 physician fee schedule proposal (CMS-1848-P, displayed July 14, 2026 and published July 16, 2026 as FR Doc. 2026-14327) describes the change in its section on maternity care services (91 FR 43880 to 43882): "At the January 2026 AMA RUC meeting, the maternity global codes were revised to delete 17 legacy CPT codes, create 12 new CPT codes, and revise 9 CPT codes describing maternity care services." It continues: "These codes were restructured from the MMM global period to individual codes to reflect changes in practice. The previous MMM global period included 12 prenatal E/M visits bundled into CPT codes 59400, 59510, 59610, and 59618."

The proposal's own Addendum B (updated July 21, 2026) has no row for 59400, 59409, 59410, 59425, 59426, 59430, 59510, 59514, 59515, 59610, 59612, 59614, 59618, 59620 or 59622. Its twelve new rows carry placeholder numbers and are labor management by day (initial and subsequent, simple and complex), vaginal delivery, vaginal delivery after a previous cesarean, primary and repeat cesarean delivery, hysterectomy after cesarean, uterine tamponade, and repair of third- and fourth-degree lacerations. None is an antepartum or postpartum care code. The rule's account of the old package as including "12 prenatal E/M visits" is the 12-visit mix priced earlier on this page. The AMA's CPT 2027 code set, not CMS's proposal, is the authority on exactly which codes are deleted.

The proposal prices the new codes and also asks whether Medicare should keep the old structure. It says: "we are considering, and are seeking comment on, the creation of 15 new HCPCS G-Codes for CY 2027 that reflect the previous MMM global code structure." It adds that these G-codes "would adopt all current conditions of payment for the MMM global codes, as well as maintain the MMM global period, if finalized," and that they would be used "in lieu of adoption of the new CPT codes for purposes of Medicare payment." Comments were due September 14, 2026. As of November 3, 2026, CMS's physician fee schedule notices page lists CMS-1848-P for CY2027 and no final rule, and the Federal Register shows no final CY2027 physician fee schedule rule.

The proposal also records why the visit count behind the old packages is changing. It says the American College of Obstetricians and Gynecologists published new guidelines in May 2025 whose sample schedule "describes 8 visits for average-risk pregnant women without medical or pregnancy complications, and 13 visits for pregnant women with greater-than-average risk." CMS adds that it is "not endorsing a reduced number of prenatal visits for pregnant women." The thirteen-visit schedule in the worked cases above is the older monthly, biweekly and weekly pattern in Michigan's manual. A schedule with fewer visits moves a change of doctor to a lower rung of the ladder.

None of the CMS or Michigan documents quoted above says how visits that fall in 2026 and a delivery that falls in 2027 are paired when two offices are involved, or how a private plan will pay under the new codes. A reader due in early 2027 who is considering a change of practice should ask each office, in writing, which code set it will use for the visits already completed and which for the delivery, and whether its price for the pregnancy is stated per visit or as a package.

Papers to collect from the first office

The worked cases depend on facts that only the offices hold. Five requests, made before the first visit at the new office, keep the two bills matched to what each office did.

1. An itemized statement by date and code. It should show how many antepartum visits the first office has billed and whether they were billed one at a time or held for one antepartum claim. Michigan's manual says antepartum care "cannot be unbundled into individual visits," so a practice that has billed several single visits and then reaches four may have to adjust. The guide to checking an itemized bill lists what to request.
2. Lab results and ultrasound reports, in writing. A second office that has no results may order its own. A repeated 80081 is a second $74.86 line, and a repeated 76805 is a second $134.00 global line or a second pair of reading and equipment lines.
3. The date of the change on both offices' records. For global surgery, section 40.2 of the Claims Processing Manual says "the date on which care was relinquished or assumed, as applicable, must be shown on the claim." That sentence is about surgical codes, but a written date of change is the simplest way to line up two offices' visit counts for a maternity pregnancy.
4. The new office's network status and your plan year. The guide to the birth hospital bill with insurance works through three plan designs, and deductible versus out-of-pocket maximum covers how a limit applies across claims. Ask how a claim from the first office and a claim from the second office are counted toward the same deductible.
5. The delivering hospital. A new obstetrician may deliver at a different hospital, which changes the hospital layer of the bill. The guide to what a hospital birth bill includes covers it, and NICU bill cost covers the baby's separate stay if there is one.

When a statement arrives, the guide to reading an explanation of benefits shows where the allowed amount and the patient share sit. A single antepartum line may look large next to a visit-by-visit statement from the same practice. That is the code working as designed.

Paying yourself: estimates and package prices

A patient who pays without insurance, or who chooses not to use it, has a federal right to a written estimate. Under 45 CFR 149.610 a practice must give an uninsured or self-pay patient a good faith estimate on request, and the section defines the expected charge for a self-pay patient as the practice's cash pay rate or established rate, reflecting any discounts for self-pay patients. Two parts of the rule fit prenatal care. Paragraph (b)(1)(x) allows one estimate for repeated services: "A convening provider or convening facility may issue a single good faith estimate for recurring primary items or services if the following requirements are met, in addition to the requirements under this section: (A) The good faith estimate for recurring items or services must include, in a clear and understandable manner, the expected scope of the recurring primary items or services (such as timeframes, frequency, and total number of recurring items or services); and (B) The scope of a good faith estimate for recurring primary items or services must not exceed 12 months." If more recurrences are expected beyond 12 months, a new estimate is required. A prenatal course of about nine months is inside that limit, though whether a practice treats prenatal visits as recurring services for this purpose is for the practice to say.

Paragraph (b)(1)(vii) bears on a change of practice. It requires a new estimate "if a convening provider, convening facility, co-provider, or co-facility anticipates or is notified of any changes to the scope of a good faith estimate (such as anticipated changes to the expected charges, items, services, frequency, recurrences, duration, providers, or facilities) previously furnished at the time of scheduling," and the new estimate is due no later than 1 business day before the items or services are scheduled. A patient who moves to a new office should therefore ask the new office for its own estimate and not carry the first one forward. The text is the version in effect on October 28, 2026. The guide to Good Faith Estimates covers the timing and the dispute process, and the guide to asking for the cash price gives a script.

A package price needs more detail than an estimate to be comparable. Ask the practice to state in writing how many visits the price covers and what happens to the price if the patient leaves before delivery, since what happens to an unused part of a paid package is set by the practice's own terms, which the federal rules cited here do not address. Ask which of the lines in this guide are outside it: ultrasounds, blood work, screening tests, the group B strep test, the drug lines, and hospital and anesthesia charges. A practice that quotes 59400 should say which of its own tests and scans it counts as included, and a practice that quotes visits should say whether it will bill the antepartum code at the fourth visit.

For patients with limited income, two other routes exist. A health center funded under the federal Health Center Program uses a sliding fee scale, covered in the guide to the community health center sliding fee scale. And Medicaid can pay for care received before an application, within limits that change in 2027, as the guide to Medicaid retroactive coverage explains.
