Hi, Thanks! I just checked that out and its saying its for preterm infants, my patient is in her 70's. Bochdalek is a type of congenital diaphragmatic hernia and its usually diagnosed in infants, and everything I've read up on adults is that its rare, but it happens (basically they've lived with it, misdiagnosed with other issues). I found a lot of case studies but no coding help. I think because its rare it doesn't have a specific code. I had even "googled" the info and was referred to code 43335 and i thought maybe it was close, but its paraesophageal, and i confirmed w/my provider that its not the same. The other codes in the 49000 area lead me to incisional and ventral. I also have access to supercoder and someone had asked about a 4 month old patient since technically not neonatal, and supercoder stated "regardless of the age, if the type of hernia is congenital, even if the repair happened during infancy the code can be assigned 39503 as there is no fitting code for this hernia repair". Which make me question, Is the code stating that its a hernia that happens in neonatal period and can be used at any age, or its a hernia that is repaired only during the neonatal period? So confusing!!, Depends: True bochdalek hernias are congenital, and so you've managed to live 50+ yrs with it. Specially on rt side and containing only fat, you can live with it. On left, it is likely to keep growing and repairs are easier when smaller and done electively., Bochdalek is a type of congenital diaphragmatic hernia and its usually diagnosed in infants, and everything I've read up on adults is that its rare, but it happens (basically they've lived with it, misdiagnosed with other issues).
