usually insurance won't cover them, sadly a lot of companies still only see them as cosmetic, even though depending on the severity of the flatness and other factors it can cause other problems. my so wasn't a preemie but he had severe torticollis and was borderline for needing a helmet to correct his brachycephaly.
As the parent of a premature infant, plagiocephaly is a condition you should be aware of. It is quite common for premature babies to develop flat spots on the back of their head, especially if they spent a significant time in the NICU. (Due to spending so much time lying in one spot.) The best way to prevent/correct flat head syndrome is to keep infants off the back of their heads as much as possible, including time spent in strollers, bouncers, carseats, etc. and to periodically change the position of their head and neck so they don’t begin to favor a certain side.Techniques to prevent/correct early stages of flat head include alternating the side you hold your baby when feeding, standing on a different side of the the table each time you change your baby's diaper, including plenty of tummy time throughout the day and massaging the neck muscles when your baby is relaxed.
