HCPCS Level 1 codes correspond to which coding system?

• A. Current Procedural Terminology codes (CPT)
• B. ICD-10-PCS codes
• C. DRG codes
• D. National Drug Codes (NDC)

Answer: (A)

HCPCS Level I codes are the CPT codes used to describe medical procedures and services. CPT, which stands for Current Procedural Terminology, is published and maintained by the American Medical Association and consists of five-digit numeric codes used for billing and reimbursement by payers, including Medicare and private insurers, for physician services and outpatient procedures.

ICD-10-PCS codes are a separate system used to classify inpatient hospital procedures, not outpatient or professional services. DRG codes are grouping categories used to determine inpatient reimbursement, not the individual procedures themselves. National Drug Codes identify medications and drug products, not the procedures or services performed.

So, HCPCS Level I codes correspond to CPT codes.
