Clinical & Coding Specifications
Clinical Context
A patient presents to a family medicine or internal medicine clinic with symptoms suggestive of vitamin D deficiency, such as fatigue, bone pain, or muscle weakness. The provider orders laboratory testing to assess vitamin D status, specifically the 25-hydroxy vitamin D level, which is the most reliable marker for vitamin D sufficiency. The blood sample is collected and sent to an independent laboratory (Place of Service 81) for analysis. The laboratory performs the assay for CPT code 82306 to measure 25-hydroxy vitamin D, including fractions if performed. Results are reported back to the provider, who interprets them in the context of the patient's clinical presentation and any underlying conditions, such as tuberculosis or other relevant diagnoses.
