Answer: Laurie Castillo, MA, CPC, president of Physician Coding & Compliance Consulting, a physician consulting firm in Manassas, Va., and a coding expert on neurology, says that the ICD-9 code used for the consultation would be the reason for the encounter (the condition or symptom for which the primary-care physician originally sought the neurologists opinion.)
The ICD-9 code for the spinal tap may be a different ICD-9 code or the same, Castillo reports. Regardless, when performing a consultation visit on the same day as a surgical procedure, modifier -57 (decision for surgery) should be appended to the consultation code. This informs the insurance company that an evaluation and management (E/M) service resulted in the decision to perform the surgery.
