Decision – Edits with NCD/LCD Documentation Only CareSource will remove these edits as it evaluates supporting policies and communications as to reasons for implementing edits. Transparency and proactive communications are important to CareSource before implementing. Due to the fact that these edits were implemented with NCD/LCD documentation only, we will reprocess any Institutional & individual Providers/Physicians claims, dates of service back to 10/1/2015, for claims denied since the edit go live date. This will include the following edits: Glycated Hemoglobin/Glycated Protein – Go Live Date – 11/3/2016 Non-invasive Vascular Studies – Go Live Date – 11/10/2016 Polysomnography & Sleep Studies – Go Live Date – 11/10/2016 Transthoracic Echocardiography - Go Live Date – 11/10/2016 Hepatitis Panel/ Acute Hepatitis Panel - Go Live Date – 11/10/2016 Thyroid Testing - Go Live Date – 11/10/2016 Vitamin D - Go Live Date – 11/10/2016 Note: Just because a claim is reprocessed does not mean that it will result in payment. Additional ICD-10 standard coding edits have been updated in our system which have led to an increased denial rate. (Ex. ICD-10 code billed may only be used as first-listed or primary diagnosis position.) We will allow these claims to be corrected and resubmitted until 7/1/2017 and waive timely filing.
