Client Experience

“The entire Customer Service team has been extremely helpful to me and our staff over the years. Their willingness to answer any question, attention to detail, support and follow up means a lot. In the ever-changing healthcare insurance industry the management of coverage and claims can be a frustrating full-time effort. Your team has helped me better understand process, claims and cost responsibilities – no doubt saving us hundreds, if not thousands, of dollars by simply doing the legwork for us. I can’t say enough for what it means for someone to offer to call providers and insurers and work out solutions on our behalf – always with punctual updates, always completed within the promised timetable, and always with a pleasant, ‘how-can-I-help-you’ demeanor. The KTBServ team is a true champion & advocate for our employees.” -Director of Operations, Nave Newell

More examples of how the KTB Serv team have recently assisted our clients and their employees. 

“An employee emailed KTB Serv because she was denied a medication to treat a chronic condition.  We placed a call to the carrier and learned that the prescription was denied because the medication required a pre-authorization. I was able to contact the provider and work with them to submit the prior authorization, which was approved by the carrier and the member was able to get the medication.”


“I received a call from an employee who needed assistance with a newborn delivery related claim that was processed incorrectly by the carrier. The claim was originally processed under the newborn and applied a 50% coinsurance, which caused the member to get a bill for almost $4,000.  I contacted the carrier on the employees’ behalf to explain that the services should be processed under the mother’s coverage and not the newborn. The carrier agreed and reprocessed the claim. The claim was paid at 100% since the employee had already met her out-of-pocket maximum for the year.”


“We received a call from an employee who received two bills for over $1,000 for a colonoscopy that he expected to be covered at 100%.  The providers had billed for a diagnostic colonoscopy instead of a preventive colonoscopy.  After several calls to the providers, the carrier and the billing offices, I was able to have the claims rebilled as preventive and paid at 100%.”
