Bilateral Lengthening of Growing Rods
The patient is an 11-year-old male with neuromuscular thoracolumbar scoliosis, who is status post insertion of growing rods. He had previously undergone lengthening of the growing rods on two occasions, and now presents for bilateral open lengthening of the growing rods. The surgeon loosened the set screws and using a rod holder and distractor, both sides of the thoracic spine were lengthened approximately 1 cm. We are considering several possibilities for the principal diagnosis code: Z45.89, Encounter for adjustment and management of other implanted devices; Z47.82, Encounter for orthopedic aftercare following scoliosis surgery; and Z46.89, Encounter for fitting and adjustment of other specified devices. What are the appropriate diagnosis and procedure codes? ...

Article Overview
This article reviews a pediatric spine surgery scenario involving follow-up management of implanted growing rods after prior scoliosis treatment. It is relevant for coders working with orthopedic aftercare and device-management encounters and focuses on diagnosis-code selection considerations for the encounter type.
Why This Topic Matters
Accurate coding for postoperative visits involving implanted spinal devices depends on understanding whether the encounter is primarily for device management or orthopedic aftercare. This article helps coders evaluate the appropriate diagnosis-code category for a growing-rod lengthening encounter.
