Itemized vs. Global Maternity Billing: Which Applies to Your Patient?

Every obstetric claim starts with one question: global or itemized? Bill the global package when you shouldn't and the claim denies or overlaps another provider's billing. Itemize when you should have billed globally and you may be accused of unbundling. Fail to bill at all because the situation is unclear — the most common outcome — and the practice simply loses the revenue.

Here's how to decide, with a decision tree and the scenarios that cause the most confusion.

The rule

Global billing applies when the same physician or group provides all of the routine antepartum care, the delivery and the routine postpartum care.

Itemized (component) billing applies when that's not the case — when the care is split between providers or payers, or when the pregnancy doesn't end in a delivery by your practice.

It's not a preference. It's determined by what actually happened.

The decision tree

1. Did your practice (or group) provide antepartum care?
   • No → skip to delivery.
   • Yes → did you provide all of it, from the first visit? If not, count your visits.
2. Did your practice deliver the baby?
   • No → bill antepartum care (E/M for 1–3 visits, 59425 for 4–6, 59426 for 7+) and postpartum care if you provided it (59430).
   • Yes → continue.
3. Did your practice provide all antepartum care, the delivery and postpartum care, under one payer?
   • Yes → global: 59400, 59510, 59610 or 59618.
   • No → itemize: antepartum components + the right delivery code (delivery only or delivery + postpartum) + postpartum only if separate.

The component codes

Common scenarios

Scenario 1: Transfer in late in pregnancy

Prenatal care started elsewhere; the patient joined your practice at 32 weeks for five more visits, and you delivered vaginally and provided postpartum care.

Itemize: 59425 (5 visits) + 59410.

Scenario 2: Transfer out before delivery

Your practice provided nine prenatal visits; the patient moved away at 30 weeks.

Itemize: 59426, billed once her care with you ends.

Scenario 3: Insurance change mid-pregnancy

Your practice provided all care, but coverage changed at 24 weeks. Six visits under Plan A; six visits, delivery and postpartum under Plan B.

Itemize by payer: Plan A — 59425; Plan B — 59425 + 59410 (or as Plan B's policy specifies). Some payers allow a global code with a date span limited to their coverage period — check the policy.

Scenario 4: Covering physician outside your group delivers

Your practice provided all prenatal care; an on-call physician from another group delivered; your practice provides postpartum care.

Itemize: your practice bills 59426 (if 7+ visits) and 59430; the delivering physician bills 59409 (vaginal) or 59514 (cesarean).

Scenario 5: Pregnancy loss

Your practice provided three prenatal visits before a first-trimester loss.

Itemize: E/M codes for the three visits, plus any procedure codes for treatment of the loss.

Scenario 6: Everything with one practice and one payer

All prenatal care, the delivery and postpartum care by your group, single payer throughout.

Global: 59400 (vaginal), 59510 (cesarean), 59610 (VBAC) or 59618 (cesarean after attempted VBAC).

Payer variations to know

• Some Medicaid programs require visit-by-visit billing of antepartum care regardless of who delivers, often with the TH modifier. See our TH modifier guide.
• Some payers have exceptions allowing the global code when only one or two visits were provided elsewhere. Keep the written policy on file if you rely on it.
• Date-of-service conventions differ for component codes — some want the last antepartum visit date for 59425/59426, others a span.
• Timely filing applies to each component claim separately.

Reducing the guesswork

The decision is easy when the facts are clear. It's hard when nobody recorded them. Build these into your workflow:

• Pregnancy registry: first visit date, estimated due date, visit count, provider and payer at each visit.
• Transfer documentation: dates and the other practice's name, for transfers in and out.
• Eligibility re-verification during pregnancy so payer changes are caught. See eligibility verification.
• Monthly reconciliation: every pregnancy should end in a billed global code, billed components, or a documented reason.

How 2027 changes the question

On January 1, 2027, the global maternity package is deleted. Every practice will report prenatal and postpartum visits per encounter with E/M codes, and the delivering clinician will report labor management and delivery with new codes. In effect, all obstetric billing becomes itemized. That removes the global-vs.-component decision — but adds new ones, like selecting E/M levels for each prenatal visit and labor complexity for each day. Pregnancies that span the transition will need special attention. See the 2027 maternity transition guide.

Quick-reference summary

• One group, all care, one payer → global code
• Care split between groups → each bills its own components
• Payer changed → split by coverage period (per payer policy)
• Pregnancy ended before delivery → bill antepartum care provided
• 1–3 visits → E/M; 4–6 → 59425; 7+ → 59426
• From January 1, 2027 → per-encounter reporting for everyone
