Why This Topic Matters

Determining whether a bone density study is treated as screening or diagnostic can affect claim processing, patient cost-sharing, and diagnosis code selection. The article also highlights why ICD-9-CM-to-ICD-10-CM crosswalks and index lookups may lead to different code families, making careful review important for accurate reporting.
