What is the unique ten-digit identification number required by HIPAA for all health care providers?

• A. NPI Number
• B. E Codes
• C. ICD Codes
• D. CMS Rules

Answer: (A)

HIPAA requires a single, universal provider identifier for health care providers: the National Provider Identifier (NPI), a 10-digit numeric number assigned through the National Plan and Provider Enumeration System (NPPES). This identifier is used in all HIPAA-covered transactions—claims, eligibility checks, referrals, and more—to uniquely identify the provider across payers and systems. It standardizes identification nationwide, replacing varying identifiers like state licenses in electronic workflows. The other options are not provider identifiers: E codes and ICD codes are coding systems for conditions and external causes, and CMS rules refer to regulatory guidelines rather than an ID. So the ten-digit NPI is the required identifier.
