Question: North Carolina Subscriber Answer: Prior trauma, such as a previously broken bone or other injury, can cause patients to experience back pain. If the patient's pain stems from a previous condition, you may code that diagnosis to justify pain management procedures your neurologist performs. Depending on the situation, there may be late-effect codes or V codes that you may report in addition to the current complaint that show a late effect or a personal history of trauma. Option 1: • 338.21 -- Chronic pain due to trauma • 723.1 -- Neck pain • 905.1 -- Late effect of cervical closed fracture. Option 2: Personal history "V codes" provide additional information to the payer indicating that the patient has had this condition or disease in the past but do not include any causality for the patient's current complaints. The key to the correct coding of these contributory conditions is making sure they are appropriately documented in the medical record. This information is central to justifying medical necessity.
