What is CPT in Healthcare ? | Types and Uses of CPT codes

CPT is the abbreviation of Current Procedural Terminology codes, 

which are numerals given to every duty and service a medical professional provides. 

A code may be associated with a test in the laboratory or a normal check-up. 

Medical, surgical operations, and diagnostic procedures are tracked and billed using codes for CPT. 

Insurance companies utilize CPT codes to calculate the amount to pay suppliers.

What Is CPT in Healthcare?

The CPT codes were first issued in 1966 by the American Medical Association (AMA), and they have modified these yearly. 

The codes for CPT were initially developed for doctors and surgeons, but at the beginning of the 1990s, other certified medical providers were added to the system. 

Various healthcare providers now widely use the codes, including dietitians, optometrists, nurse practitioners, chiropractic professionals, podiatrists, physiotherapists, psychologists, and audiologists.

To simplify reports, improve accuracy, and boost efficiency, doctors and other physicians can record medical procedures and services using the codes for CPT. 

A strict, accessible, and transparent procedure monitored by the CPT Editing Panel is essential to establishing and administration of the coding system for the CPT. 

This AMA-convened procedure, which has been in place for over fifty years, ensures that medically acceptable codes are consistently given, upgraded, and preserved to represent modern clinical procedures and medical innovation appropriately.

Medical insurance carriers, healthcare facilities, and other physicians submit claims and receive reimbursements using this medical coding created and stored by the American Medical Association (AMA). 

The three categories of the CPT codes are assessment and administration, surgery, and radiography. 

Each area has a unique set of codes to quantify the effectiveness of certain operations. 

To guarantee correct invoicing, medical professionals and billers should know the CPT system’s codes.

What are the types of CPT codes?

The CPT guide is organized into three main categories, each with specific goals that are described below:

Category I:

Medical coders most frequently record operations and services using the CPT Category I codes. 

The CPT codes are updated annually by the American Medical Association (AMA). 

Only codes in category I have a length of five digits. 

The range of these numbers is 00100 to 99499. 

There are specific instructions for using and locating every section of codes for CPT sets. 

This category is further broken down into the following six significant subcategories.

  • Services for management and evaluation – 99091-99499
  • Services in anesthesia – 00100-01999
  • Surgery services – 10004-69990
  • Radiology procedures – 70010-79999
  • Pathology and laboratory services – 80047-89398
  • Medical procedures and services – 90281-99607

Category II:

The idea behind using these Category II codes is to make it easier to manage quality improvement programs by enabling consistent reporting that records the non-performance or performance of services. 

Additional tracking numbers fall under CPT Category II codes. 

These four-digit alphanumeric codes all conclude with a “F.” 

These codes are less important and optional. 

Therefore, their use is not essential to accurate medical coding. 

Codes in Category II are between 0001F to 9007F.

  • Composite Measures – 0001F-0015F
  • Patient Management – 0500F-0584F
  • Patient History – 1000F-1505F
  • Physical Examination – 2000F-2060F
  • Diagnostic/Screening Results or Processes – 3006F-3776F
  • Preventive, Therapeutic, or Other Interventions – 4000F-4563F
  • Follow-up or Other Outcomes – 5005F-5250F
  • Patient Safety – 6005F-6150F
  • Structural Measures – 7010F-7025F
  • Non-Measure Category II Codes – 9001F-9007F

Category III:

Medical studies, recently completed services or treatments on people, and other uses of developing technology are all reported using CPT Category III codes. 

These codes are short-term and must either be authorized for a Level I position for five years, extended for an additional five years, or eliminated from the book.

In addition, Category III CPT codes are given in numerical sequence rather than according to anatomical location. 

These transient alphanumeric numbers are used for novel and evolving processes, services, and technologies. 

They were made to gather information, evaluate, and, in certain cases, pay for new methods and services that did not previously fit the requirements for codes under Category I.

How to Use CPT Codes?

New CPT coders have much to learn about rules, assertions, code descriptors, guidelines, and recommendations. 

The first need is that procedural coding requires a thorough understanding of anatomy and medical terms. 

A person must be able to understand medical records and code language in order to choose the appropriate code. 

They must know the nature of the operation, how the doctor carried out the procedure, and what code descriptor best reflects the specifics of the work done.

Furthermore, because clinicians can carry out procedures requiring a list of CPT codes from any chapter of the code book, they must have a broad understanding of anatomy and medical terms. 

The specialties within which a physician can work are not considered a limiting factor in the codes that they may report. 

A primary care coder must assign a suitable X-ray code if a doctor with primary care analyzes an X-ray, even if X-ray codes are categorized under radiology.

Significance of the CPT Coding Guidelines

The AMA offers CPT code guidelines that specify the time and way of assigning codes, the codes that may and cannot be submitted together, and other elements essential to adherence coding.

The importance of carefully reading the CPT guidelines presented in each segment and their subsections before identifying codes within the given category cannot be overestimated. 

It’s equally crucial to consider getting the right qualifications and training before taking an assignment where your duties will include calculating and submitting codes on medical billings

It is the easiest method to guarantee accurate coding and maximize your company’s reimbursement.

Changes to management and evaluation codes

The medical coding standard CPT 2023 adds 101 new codes across the existing code set. 

However, insights into the modified and deleted codes are essential. 

The updated evaluation and management (E/M) codes must first be comprehended in the context of the deleted cpt codes for 2023 from that area.

  • The codes for observation care discharge services involving 99217, the codes for first observation care involving 99218–99220, and the codes for following observation care involving 99224–99226 are removed from the Hospital Observation Services heading.
  • The codes for outpatient and inpatient appointments under the title “Consultations” have been deleted.
  • Code 99318 for other nursing institution services has been removed.
  • The custodial care codes for existing patients (99334-99337) and newly admitted patients (99324-99328) in domiciliary, nursing home, or residential care facilities are deleted.
  • The code for the new patient home visit, 99343, is removed under the category “Home Services.”
  • Codes for prolonged services add-ons 99354–99357 have likewise been deleted.

Additionally, for 2023, several codes under Category III are removed. 

These services possibly developed into Category I codes or might have been considered irrelevant. 

Codes for laparoscopy 49652-49657 are additionally removed.

Understanding the CPT Modifiers.

Medical and healthcare operations are already challenging; thus, additional data is needed when it concerns coding for medical purposes. 

Modifiers to CPT Codes perform this by providing any necessary further details about the service or treatment conducted. 

These modifiers could offer extra, but helpful, details about:

  • The total number of treatments or services provided (if exceeding one).
  • The need for that specific surgery in terms of health.
  • The treatment location, such as the site or places where the medical treatment was provided.
  • If both sides of the body underwent therapy.
  • The total number of surgeons involved in the surgery (if exceeding one).
  • The technique was altered or extended beyond what is usually done.
  • And any extra details required for accurate healthcare billing and reimbursement.

Structure related to CPT Modifiers.

CPT modifiers are made up of two characters, either alphanumeric or numerical.

However, number modifiers, such as modifier 22, modifier 59, etc., are commonly employed. 

The CPT modifiers listed below represent some of the more popular ones.

  • Modifier 25:

In health care billing, modifier 25 denotes essential personal evaluation and management (E&M) treatments performed on the same day as the treatment or other service provided by the same doctor or a different medical professional.

  • Modifier 26:

The professional component (PC) is the term used to describe this modifier. 

The services of a doctor, who may also supervise the test-taking procedure or analyze the findings, may be included in this professional segment. 

When a doctor offers assistance but hasn’t conducted the test, modifier 26 must be applied.

  • Modifier 59:

In medical billing, a different procedural service is designated by the modifier 59. 

In some situations, a medical professional may be forced to state that service was different from and unrelated to any other services provided on a single day.

However, among the most commonly employed modifiers in healthcare billing is modifier 59.

In the case that no other significant modification applies, modifier 59 needs to be applied as an alternative. 

In addition to employing modifier 59 and providing evidence to support its usage, including emphasizing that the services were provided independently, paperwork is also crucial.

Introduction to the Healthcare Common Procedure Coding System (HCPCS)

Creating HCPCS codes is the responsibility of centers for Medicare and Medicaid. 

The acronym HCPCS refers to Healthcare Common Procedure Coding System. 

Healthcare professionals use it to submit medical benefits claims to their insurance businesses. Anyone may utilize it to gain entry to HCPCS processes. 

It is cost-free and has three different levels of operation. 

Both direct and indirect medical staff are impacted in different ways by each level.

  • Level I

The codes for CPT covered by the American Medical Association are included at Level I. 

Direct healthcare providers mostly utilize codes from the CPT to provide medical treatments for patients.

  • Level II

Codes at Level II are linked to non-physical service providers. 

This level includes ambulance services, broken down into four numerals and capital letters.

  • Level III

Another name for Level III is local codes. 

The patient’s medical background is checked using HCPCS codes, explaining particular programs’ insurance policies.

What is the difference between CPT And HCPCS Code?

HCPCS is the acronym for Healthcare Common Procedural Coding System while the CPT is the acronym for Current Procedural Terminology. 

The major differences between CPT and HCPCS codes are as follows:

  • Ownership and protection:

The Healthcare and Information Probability and Protection Act of 1976 created HCPCS codes. 

These codes are open, meaning they are available to everyone without any payment. 

Whereas the American Medical Association has authorized the codes of CPT as trademarks, so it requires payment for the procedures for accessing the codes.

  • Significance:

For the delivery of medical services, HCPCS codes offer a consistent description. 

At the same time, codes for CPT offer a consistent description for the medical workers to recognize these codes.

  • Divisions:

There are three levels of HCPCS codes: Level I, Level II and Level III. 

In contrast, the codes for CPT are categorized as Category I, Category II, and Category III.

  • Impact:

HCPCS codes impact both direct healthcare providers and indirect providers of healthcare. 

At the same time, the codes for CPT are responsible for delivering processes and methods for the patient’s operations.


Since its creation, the CPT has changed, and the AMA has established an accurate system for keeping track of its validity and adjusting it to take account of advancements in healthcare technology and medical activity. 

The AMA’s regulations are very clear, and in the long term, doctors and patients are most effectively served by strictly following the CPT process’s guidelines.

CPT codes are letter-number combinations that correspond to medical services and equipment. 

The AMA created a CPT coding system to ensure that medical professionals consistently record the services they offer to patients. 

The billing and reimbursement of medical procedures heavily rely on the CPT coding system. 

It is crucial to utilize the right code when reporting a claim to guarantee that you get a fair price for the services you have provided. 

Medical coders in the field frequently utilize software with method code lookup to immediately access a set of codes from CPT and descriptions.

The secret to successful coding is remaining up to date and always referring to the code patterns applicable to the current operation date. 

You should be able to locate the appropriate code(s) for your treatment or service without delay by comprehending how CPT codes operate while employing the information mentioned above.
