Who writes HCPCS codes?

Editorial team Published on

The Centers for Medicare & Medicaid Services (CMS) is responsible for developing and maintaining HCPCS Level II codes, while the American Medical Association (AMA) develops and maintains HCPCS Level I (which consists of CPT codes).

HCPCS Code Levels and Responsibilities

  • Level I (CPT Codes): Developed and maintained by the American Medical Association (AMA). These 5-digit numeric codes report physician and non-physician services and procedures.
  • Level II (Alpha-Numeric Codes): Developed and maintained by the Centers for Medicare & Medicaid Services (CMS). These codes identify products, supplies, and services like ambulance rides, durable medical equipment, and injections not covered by CPT codes.

Who is responsible for HCPCS codes?

Different organizations are responsible for the two main levels of the Healthcare Common Procedure Coding System (HCPCS), depending on the specific code set.

HCPCS Level I (CPT Codes)

HCPCS Level II (Alphanumeric Codes)

  • Responsible Organization: The Centers for Medicare & Medicaid Services (CMS) maintains Level II codes with input from the HCPCS Workgroup.
  • Details: Level II consists of alphanumeric codes used to identify products, supplies, and services not found in CPT. Examples include ambulance rides, drugs, and durable medical equipment. The Pricing, Data Analysis and Coding (PDAC) contractor also helps categorize specific equipment.

What is the difference between a HCPCS and CPT code?

The main difference is that CPT codes describe the medical service or procedure performed by a provider, while HCPCS codes describe the supplies, equipment, and items used during treatment.

What is a CPT Code?

  • Stands for: Current Procedural Terminology.
  • Purpose: Describes the professional work and clinical actions done by a doctor or clinician (like an office visit, surgery, or physical therapy session).
  • Format: Five-digit numeric code.
  • Managed by: The American Medical Association (AMA).

What is an HCPCS Code?

  • Stands for: Healthcare Common Procedure Coding System (pronounced "hick-picks").
  • Relationship: HCPCS is split into two levels. Level I consists of standard CPT codes. Level II covers everything CPT leaves out.
  • Purpose (Level II): Used for durable medical equipment (like wheelchairs), ambulance services, injections, and medical supplies.
  • Format (Level II): Alphanumeric, starting with a single letter followed by four numbers (e.g., A-to-V codes).
  • Managed by: The Centers for Medicare & Medicaid Services (CMS).

Key Comparisons

  • CPT: Focuses on what the provider did (the action/service).
  • HCPCS Level II: Focuses on what the provider used (the material/item).
  • Updates: CPT is updated annually by the AMA, whereas HCPCS Level II is updated more frequently by CMS.

How are HCPCS codes organized?

Healthcare Common Procedure Coding System (HCPCS) codes use a two-level structure format to process medical claims.

HCPCS Level I

  • Format: Five-digit numeric codes.
  • Content: Consists of Current Procedural Terminology (CPT) codes.
  • Purpose: Identifies medical services and procedures performed by physicians and other healthcare professionals.

HCPCS Level II

  • Format: Alphanumeric structure consisting of one single alphabetical letter (A through V) followed by four numeric digits.
  • Content: Managed by the Centers for Medicare & Medicaid Services (CMS).
  • Purpose: Identifies products, supplies, injections, and services not included in Level I, such as ambulance services or durable medical equipment.

Modifiers

  • Format: Two-digit numeric or alphanumeric characters.
  • Purpose: Appended to Level I or Level II codes to give extra details about a service, like a bilateral procedure or a specific service location.

Are HCPCS codes only for Medicare?

No, HCPCS codes are not only for Medicare; they are also used by state Medicaid programs and many private insurance companies.

The Healthcare Common Procedure Coding System (HCPCS) was originally built for Medicare, but the codes became a national standard under federal law.

Who Uses HCPCS Codes?

  • Medicare: Required for billing non-physician services, medical equipment, and supplies.
  • Medicaid: State programs use them to process claims for similar medical items.
  • Private Insurers: Many commercial health plans adopt HCPCS Level II codes, though coverage rules differ by company.

Key Points to Remember

  • Not a guarantee of payment: Just because a HCPCS code exists does not mean an insurance plan will pay for the item.
  • Check with the payer: Providers must always verify benefits with a specific insurance company before submitting a claim.
  • Learn more details about how these codes work in the AAPC Guide on HCPCS.

Who releases HCPCS codes?

The Centers for Medicare & Medicaid Services (CMS) is responsible for developing and maintaining HCPCS Level II codes, while the American Medical Association (AMA) develops and maintains HCPCS Level I (which consists of CPT codes).

HCPCS Code Levels and Responsibilities

  • Level I (CPT Codes): Developed and maintained by the American Medical Association (AMA). These 5-digit numeric codes report physician and non-physician services and procedures.

Is 99214 a CPT or HCPCS code?

Code 99214 is a CPT code.

Overview

  • Type: Current Procedural Terminology (CPT) Evaluation and Management (E/M) code.
  • Description: Represents a Level 4 office or outpatient visit for an established patient.
  • Requirements: Requires a moderate level of medical decision-making (MDM) or a total time of 30 to 39 minutes on the date of the encounter.

How do I know when to use HCPCS codes?

You use HCPCS Level II codes when billing for products, supplies, equipment, and services that standard CPT codes do not cover.

When to Use HCPCS Codes

  • Billing for Items and Supplies: Use them for tangible items like durable medical equipment (wheelchairs, walkers), prosthetics, orthotics, and non-self-administered injections or drugs.
  • Reporting Non-Physician Services: Use them for services like ambulance transportation or specific professional procedures required by government payers.
  • Filling CPT Gaps: If a medical procedure or service has a CPT code, use the CPT code. If a specific item or service lacks a CPT code but has a matching HCPCS Level II alphanumeric code (one letter followed by four numbers), use the HCPCS code.
  • Government and Insurance Claims: Use them primarily for Medicare, Medicaid, and private insurance claims that mandate distinct supply and product reporting alongside clinical procedures.

What is the golden rule in medical billing and coding?

The golden rule in medical billing and coding is “If it isn't documented, it didn't happen” (or “Never code or bill for a service that is not documented in the medical record”).

What the Rule Means

  • Proof of Service: Every test, procedure, diagnosis, or consultation must be clearly recorded in the patient's chart.
  • Justification: Insurance companies require written proof to verify medical necessity before they approve and pay a claim.
  • No Assumptions: Even if a physician performed a procedure, it cannot be billed if it is missing from the clinical notes.

Why the Golden Rule Matters

  • Prevents Denials: Missing notes lead to automatic claim rejections and delayed payments from insurance payers.
  • Stops Audits and Fraud: Proper documentation protects a practice during legal reviews and compliance audits by proving the care was legitimate.
  • Ensures Patient Safety: Clear records help maintain accurate patient histories and proper continuity of care.

You can learn more about how documentation drives coding standards through resources like Modernizing Medicine.
