Can anyone please give me detailed information on these two modifiers and when to use them? Thank you

Modifier GB (Claim being re-submitted for payment because it is no longer covered under a global payment demonstration), identifies services for which a provider submits a claim under a global payment demonstration and later determines the patient or the service did not qualify for inclusion, so he resubmits the claim under the traditional fee for service program. Global payment demonstration projects reimburse a package price for a group of services based on the expected costs for an episode of care, as a combined quality improvement and cost reduction measure. The original claim may have been a no pay claim, one that identifies services or items for informational purposes without expectation of reimbursement. Modifier GB is an informational modifier.

Modifier TH (Obstetrical treatment/services, prenatal or postpartum), indicates that a female patient receives medical care for problems related to her pregnancy and following the birth of the child. The provider may render requisite treatment for the various aspects of pregnancy, including monitoring the health of the mother and providing medical support for the recovery of the mother following a cesarean or normal delivery. Medicare does not pay for this modifier.
