Coding Maternity Care with Insurance Change

Coding Maternity Care with Insurance Change

When coding maternity care, you typically will report a “routine, uncomplicated” service, using a single, “global” obstetric care code, based on the type of delivery:

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) and postpartum care, after previous cesarean delivery

59618 Routine obstetric care including antepartum care, cesarean delivery, and postpartum care, following attempted vaginal delivery after previous cesarean delivery

If the physician does not perform all services as described by the global codes (e.g., the patient receives irregular or late prenatal care, experiences a miscarriage or terminates a pregnancy, or changes providers during the pregnancy), you may report delivery, antepartum care, and postpartum care independently of one another, using dedicated codes. CPT® maternity care guidelines (and related CPT Assistant articles) give ample guidance to apply these maternity care codes correctly, in most situations.

Change in Insurance Means a Change in Coding

But, there is a common scenario when coding maternity care that CPT® guidelines do not address: The patient switches insurance during the pregnancy, while retaining the same physician for the entire pregnancy.

In such a case, proper billing will depend on the payer. As a general rule, each insurer will pay only for that exact portion of care for which it is responsible. To illustrate, the following guidance is taken from the Health Reimbursement Policy of private insurer Moda health (updated April 2018):

The patient presents to your clinic for obstetrical care in the 8thweek of her pregnancy. She is seen monthly, and in her 21stweek she has a change of insurer. She continues to be seen monthly for the remainder of her first 28 weeks, then biweekly to 36 weeks, and then weekly until her delivery at 39 weeks for a total of 13 visits. The clinic performs the vaginal delivery and provides the postpartum care.

The billing office bills the first four visits to carrier A with CPT® code 59425 [Antepartum care only; 4-6 visits] using the date of the first visit as the From date and the date of their last visit before the change in insurance as the To date. The additional nine visits are billed to carrier B with CPT® code 59426 [Antepartum care only; 7 or more visits]. This claim also bills the delivery and postpartum care with CPT code 59410 [Vaginal delivery only (with or without episiotomy and/or forceps); including postpartum care]. The delivery date should be used as the date of service for all services on both claims.

There will be exceptions to this general rule when coding maternity care. For example, if the patient delivers late or has multiple “worried well” visits from the point she switched insurance, the requirements of insurance “B” might be met, and global billing (e.g., 49400)—not itemized billing—may be warranted. This is a gray area; therefore, your best strategy is to contact insurance “B” prior to billing.

    What happens it the patient has a change of insurance and the policies overlap? Say the patient has insurance a and it ends on Aug 31. Insurance B begins on 06/01. Can we use the visits from June and July for insurance B and bill a global charge? AN =d if there are enough visits from the Insurance A bill out an Antepartum visit?
    Thanks, Cindy

    What is the documentation that is needed to bill codes 59425 & 59426 (is what is listed in the CPT book good enough, the E/M guidelines don’t need to be followed?).
    I believe these codes cover a time span and the code is only billed once in that time span.
    I have not billed maternity services before and we have a provider that is billing one of these codes for every visit.

    I have not billed for maternity services before and have a provider billing the 59425 & 59426 for every visit.
    Do these codes have a time span and should only be billed once in that time span.
    For the documentation should the information listed in the CPT book be the only thing that is needed…that the E/M guidelines do not need to be followed for these codes.
    Thank you for your help!
