Billing Errors Caused Unnecessary Charges

I'm disappointed in multiple billing errors from Lancet that resulted in unnecessary rejections from our medical aid. We called Lancet who referred us to the medical aid, who referred us to the hospital, who referred us back to Lancet. In the end (after a few hours on the phone), Lancet used incorrect ICD-10 codes and incorrect dependant numbers when claiming, which resulted in medical aid rejections. A very unnecessary exercise. I'm fami**** with this industry, and whenever something rejects in my work, I always investigate further and start asking questions. I would let our billing department know to dig deeper so that I can prevent unnecessary payments for our patients. But it seems like no questions were asked and no investigation done as to why items are rejecting. So I'm just disappointed to have to go through this whole ordeal just for us to assist Lancet fixing their own mistakes. The big irony is, that after talking to an agent on their side for an hour, at the end he asked whether the mistakes were on their (Lancet) side. This is after mistakes were corrected (yes, on Lancet's side). So if this wasn't clear, yes the mistake was on your side.
