Why Separate Superbills
When the IBCLC field began in the 1990s, combined superbills covering both the parent and child were fairly common. In recent years, though, most US insurance companies began requiring a separate superbill for each patient, parent and child, to cleanly bill for services to each person. It does make sense: no other medical profession treats two people as a combined unit. If the company comes back asking for a combined bill, you can always redo the bill for the mom putting all the charges on one or the other.
What about multiple babies? Or multiple lactating parents? Complete a separate form for each person you treat.
