The fact that ICD-10 Codes are the only identification criteria set for a medical disease is inevitable. They provide a common language to share data across various countries and platforms. Apart from this, ICD-10 codes are a must in any medical billing process including pathology billing services. It is a necessary requirement to assign appropriate codes to pathology services like diagnostic tests and surgical procedures. This not only helps in filing a proper claim but also in maximizing reimbursements.
