Depending on how the surgeon accomplished the original procedure, you probably reported either 20661 (Application of halo, including removal; cranial) or 20664 (Application of halo, including removal, cranial, 6 or more pins placed, for thin skull osteology [e.g., pediatric patients, hydrocephalus, osteogenesis imperfecta], requiring general anesthesia). Each procedure has a 90-day global period. Periodic adjustments in the office are a component of halo care and are included in the global period.
When the global period ends, you should factor halo adjustments when deciding on an appropriate E/M level (99211-99215 for established outpatients).
