Written for education, not as billing advice. Confirm any code against the AMA CPT codebook and your payer's rules before it goes on a claim.
The fastest way to look up a CPT code is to search by plain-English keyword in an online reference tool, then confirm the description matches the exact procedure before using the code on a claim. Billing the wrong code, even accidentally, can trigger denials or audits. Confirmation against an authoritative source is not optional.
CPT stands for Current Procedural Terminology, a code set maintained by the American Medical Association (AMA). Each five-digit code represents a specific medical service or procedure. Payers (Medicare, Medicaid and commercial insurers) use CPT codes to identify what was done, match it to a fee schedule, and pay accordingly. Selecting the wrong code can mean underpayment, denial, or (in serious cases) a compliance problem.
Online reference tools are the fastest starting point. Sites that publish common CPT codes let you search by keyword and see the full descriptor. The Code Lookup on this site covers common codes for quick reference, but it does not replace the official AMA codebook for definitive billing decisions.
The AMA CPT codebook or a licensed encoder is the authoritative source. The AMA publishes a print edition annually and licenses electronic encoders. Coders typically use the index to find a keyword, then verify the descriptor in the main section. Many practice management systems embed a licensed encoder directly in the workflow.
Your practice management or EHR system is usually the most practical route in a billing department. Most clinical software includes a built-in code search linked to a licensed encoder, and it ties the code directly to the encounter record.
CMS and payer fee schedules are worth checking for Medicare work. The CMS Physician Fee Schedule look-up tool shows which CPT codes are covered and at what rate. Most payers also publish covered-services lists on their websites.
A CPT descriptor includes the procedure name, any anatomical site, and sometimes a patient age range or setting. CPT codes are organized into sections: Evaluation and Management (99XXX), Anesthesia (00100-01999), Surgery (10000s-69990s), Radiology (70000s), Pathology and Lab (80000s), and Medicine (90000s-99XXX). Knowing the section helps you navigate quickly.
Using outdated codes (CPT updates annually on January 1), selecting a similar but incorrect code, or omitting required modifiers are the most common errors. Before submitting, confirm the code is valid for the service date and that any bundling or modifier rules are satisfied. See What is a modifier in medical coding for modifier guidance.
Complex procedures, operating room cases, and anything with a compliance risk should go through a Certified Professional Coder (CPC) or equivalent credentialed coder. Looking up a code yourself is fine for routine reference; signing off on a claim for a procedure you are not trained to code is a different matter.

The AMA does not release its full CPT code set for free, but many third-party reference tools publish the most common codes. CMS publishes Medicare fee schedules with CPT codes and descriptions online at no cost. The Code Lookup on this site covers frequently used codes for quick educational reference.
99214 is a common CPT code for a moderate-complexity office visit (established patient). 93000 covers a routine ECG with interpretation. 71046 is a two-view chest X-ray. Each five-digit code maps to a specific service description in the AMA codebook.
Yes. Patients can look up CPT codes to understand what was billed. Your Explanation of Benefits (EOB) from your insurer will list the CPT codes from your claim. Knowing what each code means helps you verify your bill -- see the article on how to read an EOB for a walkthrough.
Start with the plain-English name of the procedure, search a reference tool or the AMA CPT index, read the full descriptor, and confirm it matches the actual service. For anything beyond routine office visits, consult a certified coder or the official AMA guidelines. Payer-specific rules may also apply.
