What this code covers
Source · Editorial summary grounded in 3 cited references ↓
Orthopedics orders the 25-hydroxy vitamin D level after fragility fractures, for fracture nonunion or delayed union, before spine fusion in patients at risk for poor bone healing, and in osteoporosis workups. It is the right test for vitamin D status in almost every ortho situation.
Medicare contractors have coverage policies that limit vitamin D testing to listed diagnoses, such as osteoporosis, osteomalacia, malabsorption, chronic kidney disease, and certain fracture conditions. Routine screening of healthy patients is not covered. Use the most specific diagnosis available: the fracture, the nonunion, or the osteoporosis code, not a general deficiency or fatigue code.
Frequency matters too. Repeat testing to check a response to supplementation is usually allowed, but not every few weeks. Do not confuse 82306 with 82652, which is the 1,25-dihydroxy form and is rarely the right test for an ortho question. The lab bills it under the Clinical Laboratory Fee Schedule.
