How to see what CPT codes are covered by insurance?

Editorial team Published on

You can check Current Procedural Terminology (CPT) codes and their coverage with your insurance company by logging into your insurer's online member portal or calling the customer service number on the back of your insurance card.

Steps to Check CPT Codes with Insurance

  • Use the Payer Portal Search Tools: Log into your health insurance provider's online portal. Many insurers offer a cost estimator or a Services and CPT Codes Lookup Tool (example via Blue Cross NC) to check if a specific code requires prior authorization, is covered, or is considered in-network.
  • Call Member Services: Contact your insurance company directly. Provide the representative with the 5-digit CPT code and your diagnosis (ICD-10) code to ask if the specific service is covered, requires pre-authorization, or applies to your deductible.
  • Ask Your Doctor's Office for the Codes First: Request the planned CPT codes and the accompanying diagnosis codes from your physician or medical biller before having a procedure done.
  • Verify General Code Meanings: If you need to verify what a code stands for or check proper coding guidelines, you can cross-reference the code using official resources like the American Medical Association CPT Resources or tools like Codify by AAPC.

Most users on Reddit agree that verifying nuanced or internal billing codes (like office visit levels) as a layperson can be difficult through public online tools alone, making direct communication with your provider or insurer necessary.

What are CPT billing codes and how can I find them?

Current Procedural Terminology (CPT) codes are five-digit numeric or alphanumeric codes used by healthcare providers to standardize the reporting of medical, surgical, and diagnostic services and procedures for insurance reimbursement.

What Are CPT Codes?

  • Standardized Language: They remove subjective interpretations of medical services by providing a uniform code for every specific procedure, test, or office visit.
  • Categories:
    • Category I: Main procedures and services (such as surgery, radiology, and evaluation/management).
    • Category II: Optional performance-tracking and quality-of-care codes.
    • Category III: Temporary codes for emerging and new technologies.
    • PLA / Proprietary Laboratory Analyses: Specific single-source or lab test codes.
  • Modifiers: Two-character codes added to the main number to show special circumstances, like a procedure done on the left side of the body or extra time spent.

How to Find CPT Codes

  • Official Books: The American Medical Association (AMA) publishes the updated CPT Professional Edition book annually.
  • Online Lookups: Medical coding sites like the AAPC CPT Code Lookup provide searchable databases of code ranges and descriptions.
  • Government Tools: The Centers for Medicare & Medicaid Services (CMS) maintains public lists and resource files for relative value units (RVUs) and covered services.

How to determine what CPT code to use?

To determine the correct Current Procedural Terminology (CPT) code, you must match the specific medical service, surgery, or diagnostic test performed to its exact description in official resources like the American Medical Association CPT Code Set.

Steps to Determine a CPT Code

  • Review the medical record: Read the clinical documentation, operative report, or progress note to identify the exact service, procedure, or anatomical site.
  • Identify the main term: Find the primary procedure, organ, or condition in the index of the CPT Professional Edition or an online lookup tool like AAPC CPT Code Ranges.
  • Select the section: Narrow your search down to one of the six main Category I sections: Evaluation and Management (E/M), Anesthesia, Surgery, Radiology, Pathology and Laboratory, or Medicine.
  • Read parent and child codes: Check indented sub-entries and semicolons carefully; child codes rely on the main parent code description preceding the semicolon.
  • Apply modifiers if needed: Add two-digit numerical or alphanumeric modifiers (such as modifier 25 or 59) when a service requires clarification for distinct procedural steps, anatomical sides, or separate evaluation visits.
  • Verify medical necessity: Pair your final CPT code with the correct ICD-10-CM diagnosis code to ensure the payer understands why the procedure was performed.

Medical coding uses three main classification systems to record patient diagnoses and medical services. Because there are tens of thousands of individual codes, they are organized into structured numerical and alphabetical ranges rather than a single short list.

Current Procedural Terminology (CPT) Codes

CPT codes are five-digit numbers that describe medical, surgical, and diagnostic services. They are managed by the American Medical Association.

  • 99202–99499: Evaluation and Management (office visits and check-ups)
  • 00100–01999: Anesthesia services
  • 10004–69990: Surgery procedures
  • 70010–79999: Radiology and imaging procedures
  • 80047–89398: Pathology and laboratory tests
  • 90281–99607: Medicine services and procedures

International Classification of Diseases (ICD-10) Codes

ICD-10 codes use three to seven alphanumeric characters starting with a letter. They explain the patient's diagnosis and medical necessity.

  • A00–B99: Infectious and parasitic diseases
  • C00–D49: Neoplasms (cancers and tumors)
  • E00–E89: Endocrine, nutritional, and metabolic diseases
  • I00–I99: Diseases of the circulatory system
  • Z00–Z99: Factors influencing health status and contact with health services

Healthcare Common Procedure Coding System (HCPCS Level II) Codes

HCPCS codes cover supplies, equipment, and services not defined in standard CPT codes. They start with a letter followed by four numbers.

  • A0021–A0999: Transportation and ambulance services
  • A4100–A8006: Medical supplies
  • E0100–E8002: Durable medical equipment
  • J0013–J9999: Drugs administered other than oral method
  • L0112–L9900: Orthotic and prosthetic procedures

What are the 6 types of CPT codes?

The Current Procedural Terminology (CPT) code set is divided into six main sections under Category I, which cover standard medical procedures and services.

The 6 Sections of CPT Codes

  • Evaluation and Management (E/M): Covers doctor visits, consultations, and routine checkups (such as office visits).
  • Anesthesia: Covers pain management and administration of local or general anesthesia during procedures.
  • Surgery: The largest section, covering operations and invasive procedures performed by surgeons or medical staff.
  • Radiology: Covers imaging tests like X-rays, MRIs, CT scans, and ultrasounds.
  • Pathology and Laboratory: Covers blood tests, biopsies, and tissue analysis processed in a lab.
  • Medicine: Covers non-surgical treatments and services, such as physical therapy, vaccinations, and injections.

(Note: While Category I contains these six major sections, the broader CPT system also includes Category II codes for performance tracking and Category III codes for emerging technology).
