Learn what options you have for treating cognitive deficits. Scanning your ICD-9 coding manual for an appropriate diagnosis code can give even seasoned pediatric coders a headache. You probably won't find a perfect code when head injuries are involved, but here's how to get closer than ever before. 1. Consider Procedure Code Before you've got your diagnosis code nailed down, you'll focus on the appropriate CPT code to describe your service. If the physician provides an outpatient E/M service to evaluate the concussion, you'll report the appropriate code from the 99201-99215 series. If you administer a computerized neuropsychological test to determine the impact of the concussion, report 96120 (Neuropsychological testing [eg, Wisconsin Card Sorting Test], administered by a computer, with qualified health care professional interpretation and report). If, however, you administer a non-computerized neuropsychological test, 96116 (Neurobehavioral status exam...) would be an appropriate code. If you perform both the neuropsych testing and the E/M service at the same session, you can report both codes, assuming that your documentation can demonstrate the separate nature of the two services. In that case, you'll append modifier 25 (Significant, separately identifiable evaluation and management service by the same physician on the same day of the procedure or other service) to the E/M code. Often, concussion patients will return for follow-up visits. You can report the appropriate E/M code for these visits, unless the physician performs a different service besides an E/M. For instance, if he saw the patient shortly after the concussion and the patient's only symptom was blurred vision, the doctor might want to administer a vision test after two weeks pass. If the vision test is the only reason for the visit, you'll report the appropriate code for that service. 2. Sort Out Minor Vs. Serious Injuries If your pediatrician is called in to see a patient with a head injury, you need to get straight what's involved with coding these events from a diagnosis standpoint. Minor injuries: If the patient has a contusion of the head, you should use 920 (Contusion of face, scalp, and neck except eye[s]), but remember that a contusion, by definition, includes a bruising injury that does not break the skin. You should check for exclusions in your ICD-9 book. The exclusion note for 920 refers to various other codes for more significant injuries that go beyond a basic bump on the head. When your provider doesn't document any further detail than "head injury," you should use 959.01 (Head injury, unspecified). This code also has a list of exclusions similar to 920. Significant injuries: 3. Learn the Late Effects Codes If the patient had a brain injury more than a year ago, you should look to a late effects code. Using a late effects code creates the causality relationship between a prior injury and the current condition your provider is treating. A possible example is 907.0 (Late effect of intracranial injury without mention of skull fracture). In addition, you want to code as primary the actual residual condition for which the pediatrician is seeing the patient, such as cognitive changes. What it is: Coding late effects generally requires two codes sequenced in the following order: first, the condition or nature of the late effect; and second, the late effect code. For instance, the condition code could be confusion (293.1, Confusion, subacute), followed by 907.0 (Late effect of intracranial injury without skull or facial fracture). Reporting acute injury codes for all of the subsequent services for the latent/residual condition from a single injury indicates that the patient has had repeated acute injuries rather than requiring treatment/care for the delayed recovery of the initial injury.
