You do need to bill to and from dates on the claim. Coding guidelines state that this should be a singe line with a date range. So if I split the claim, I would be billing two different claims with each claim having a 59425 on it. UHC did publish how they want you to bill, but so far, they are the only carrier I found a policy on.
Q: If a physician provides antepartum services when the “from” and “to” dates span across ICD-9-
CM to ICD-10-CM code sets, and global maternity service codes are used, such as CPT 59425 or
59426, how should the services be reported?
A: To facilitate correct payment and application of benefits in the UnitedHealthcare claims system,
when the date span crosses ICD-9-CM to ICD-10-CM code sets, the “from date” of service should
be reported with the correct ICD code from the applicable code set for that date of service.
Example: Report the diagnosis using the ICD code set that is in effect for the date of service in the
“from date” field. If the date in the “from date” field is on or before Sept. 30, 2015, use the ICD-9-
CM code. If the date in the “from date” field is on or after Oct. 1, 2015, use the ICD-10-CM code.
Note: Global maternity care codes for services that span over the ICD-10 effective date do not need
to be split on two lines to accommodate the implementation of ICD-10-CM. If an OB global code
