"The ICD-10 (the coding system health care providers use to report diagnoses, symptoms and procedures) is of tremendous utility to subrogation/reimbursement efforts ... New levels of detail in ICD-10 codes give plans important new abilities to see whether an injury can be associated with a recovery opportunity.... ICD-10 codes also tell the plan about services performed: when the member first presented with providers; continuing treatment he or she needed to repair the injuries; and treatment for complications directly connected to the injury. ICD-10 even gives plans a better chance of separating out pre-existing chronic conditions from treatment directly relating to the injury."
