Medicare Part B Quarterly Drug Spending with Clinical Descriptions

Quarterly data tracks spending for drugs administered in outpatient settings to Medicare Part B enrollees. The dataset includes consumer-friendly descriptions of drug uses, clinical indications, and manufacturers. It provides preliminary spending metrics calculated at the HCPCS code level, updated each quarter.

Use Cases

• Analyze quarterly trends in Medicare payment and beneficiary liability for specific HCPCS-level drug codes.
• Map drug spending to consumer-friendly descriptions of clinical indications and manufacturer information.
• Compare preliminary quarterly spending data against finalized annual figures to assess claims lag and data stability.

Strengths

• Provides quarterly updates, offering more recent preliminary data than the annual dataset.

Limitations
