Understanding the HCPCS Book for Medical Coding
Mar 18, 2025
Overview of the HCPCS Book
Introduction
The HCPCS book, often referred to as the Hickpix book, is the Healthcare Common Procedure Coding System, specifically Level 2.
Level 1 of HCPCS is technically CPT (Current Procedural Terminology), known as CPT-4.
Many medical coding curriculums do not cover this book extensively, although it is essential for certain coding tasks.
Victoria, a medical coder and educator, provides an overview and some demonstrations of using the HCPCS book.
Contents and Uses of HCPCS Book
Primarily used for:
Drugs and medications
Ambulance services
Durable medical equipment (DME)
Insurance-specific codes
Examples include:
"S" codes for annual GYN exams (e.g., Capital Blue Cross)
"G" codes for Medicare-specific services
Certification Exams and the HCPCS Book
For the CPC exam by AAPC:
Only five questions specifically address HCPCS Level 2 codes
Can often be passed without extensive use of the HCPCS book if proficient in other areas
For AHIMA exams:
Specific editions of HCPCS books may be required
Editions and Publishing
Various publishers produce the HCPCS books, like Optum 360 and the Coding Institute.
Differences in editions may include additional appendices or note spaces.
HCPCS Coding in Practice
HCPCS books may not be purchased annually by organizations due to cost and alternative tools like Codify.
Common uses:
DME billing (casts, crutches, artificial limbs)
Ambulance billing
Medication billing by unit dosage (e.g., 10 mg, 40 mg)
