Our office really doesn't use 59430. I am guessing that this would be used in cases that the delivery was outside of the facility and only routine global postpartum care was done. Also, with Medicaid, you wouldn't use a global code, so you would just bill out each visit with an inpatient E&M code. At least that is my thought on all of this.
Sorry, adding to this...
59430 code description says "Includes: Office/other outpatient visits following c/s or vag delivery.
So, if it is an inpatient, you would not use this code. I would think you would just use the inpatient E&M codes then.
It really is all confusing and to bill correctly for specific payers, it would be best to contact them.
