Using codes for patient tracking.
Although diagnosis and procedure codes are primarily assigned to ensure correct reimbursement, a number of codes can be used for patient tracking purposes. These codes are generally located in the "Supplementary Classification of Factors Influencing Health Status and Contact With Health Services" section of the ICD-9-CM manual, also known as the "V Codes." By using these codes to track certain segments of patient population, a practice can be prepared to forecast patient mix and anticipate specific collection or self-pay issues.
