CPT 83605

The American Medical Association (AMA) maintains all of the Current Procedural Terminology (CPT) codes. CPT codes are used for all medical, surgical, and diagnostic procedures and services. They can be used for both professional and facility billing. Physicians developed CPT codes to help manage their practices more efficiently. It provides uniformity. At the same time, it also provides uniformity to billing insurance companies. There are many types of codes: chemistry, neurology, and more. For example, CPT 83605  is a code of chemistry. It is used for the analysis of lipase.

CPT 83605 And The Other Categories Of CPT Codes

CPT codes are used for all claims submitted to Medicare, Medicaid, and private insurance companies. They can be used for both professional and facility billing. CPT codes are a standardized way of categorizing medical services. It involves procedures, surgeries, and tests performed by doctors and other healthcare professionals. Each code has its specific meaning and purpose. It allows patients access to information. The patient will know what was done during their visit with you or others working in your office.

Who Uses CPT Codes?

Medical billing companies and insurance companies use CPT codes. Besides, physicians and other healthcare providers, healthcare research organizations, and government agencies also use CPT codes. The codes report medical services, procedures, diagnoses, and additional medical information. They are based on the International Classification of Diseases (ICD). ICD is a standardized diagnostic tool used by countries around the world. The ICD-10 codes report medical services, procedures, diagnoses, and other medical information. 

Where are CPT Codes found?

CPT codes are used for all claims submissions. It includes Medicare, Medicaid, and private insurance companies. They’re also used by the Centers for Medicare & Medicaid Services (CMS) to determine reimbursement rates. CPT codes are vital for understanding your treatment costs because they provide a standard way of documenting medical services. Besides, CPT codes help to understand medical procedures are performed on patients across all healthcare settings.

Different Categories of CPT Codes

There are three main sections of Current Procedural Terminology codes, i.e, First, medicine; second, evaluation and management; and third surgical procedure codes. The AMA also maintains Category II codes. They are used only for reporting performance measures as part of quality improvement programs. Category III contains provisional codes that describe tools or technologies under evaluation. In addition, HCPCS Level I (CPT) codes are also found in AMA. Different types of CPT codes are used in chemistry. For example, common CPT codes used in chemistry are CPT code 83036 for hemoglobin and CPT 83605 for lipase enzyme.

CPT codes are a standard nomenclature for medical procedures and services. CPT codes are used in medical billing. First, they describe the type of service provided. Second, who performed it? Third, how much it costs? Finally, any other information necessary to bill for services rendered by a physician or other healthcare practitioner. 

CPT Code List

CPT codes are updated annually. A new version of CPT becomes effective each January 1st. In contrast, insurers have different policies regarding using unique codes. They usually need the code from the current year. Code can be from the one-year previous list. However, you can only find new codes in the updated CPT code list.

CPT codes are updated to reflect changes in medical practice. Besides, it reflects changes in insurance policies over time. Still, they may also be revised if new conditions or procedures are added to an existing body system covered by Medicare.

CPT codes are available in several formats, including print, online and CD-ROM. In addition, the current edition of CPT is available at no charge through the AMA website. You can also get it by calling (800) 535-9265 between 7:00 a.m. and 5:00 p.m. Central Time, Monday through Friday.

CPT Codes and Modifiers

ICD Codes are used to report diagnoses and procedures. So they’re helpful for research purposes. But not so much when trying to ensure that your practice complies with insurance regulations.

The first step to getting your coding right is understanding what each code means and how it should be used to communicate clearly about the services provided. Thus, medical professionals, billing companies, and insurance companies must use the same language.

That’s where CPT codes come in.CPT codes are the mainstay of billing and payment. They describe a specific procedure or service, such as an office visit or surgery. Each procedure is assigned a number used in insurance claims to pay you correctly for your services. The CPT code for chemistry tests ranges between 82963- 83690. For example, CPT 83605 is used for testing lipase in the large intestine.

There are two sets of CPT Codes modifiers that are used to describe the nature of a condition or procedure:

  • CPT codes, which are the mainstay of billing and payment
  • MAC Codes (Modifier Abbreviations). It can be used when you need a more detailed description than what’s provided by CPTs.

CPT Codes and Their Descriptors

Each CPT code has a short description associated with it called a descriptor. These descriptors are explicitly written to aid in accuracy. Besides, it helps to assign the correct code during the medical billing process. The descriptor associated with any given code may change with each new update to the code set.

Keep up to date on your knowledge of CPT codes so you can make sure that your practice is using them correctly. Your approach should use the most current versions of these codes if you cannot access the most recent versions of CPT codes. You can ask for a CPT code list from your nearby medical billing service provider.

Medical Billing

CPT codes are used in the medical billing process. CPT codes help to identify services performed and determine appropriate reimbursement. For example, a physician may use a CPT code as a starting point for calculating charges from their patients. But it can be challenging to know where your particular code falls within this system.

To understand how these codes work, we must first look at how they were created by the American Medical Association (AMA). In 1992, the AMA developed a set of standards that included a number of 5400-5599 codes under Current Procedural Terminology (CPT). The list contains detailed descriptions of each procedure performed by physicians. In addition, the list covers all specialties and subspecialties. 

These codes identify each specific type of treatment. It uses descriptive terms such as “diagnosis” or “treatment plan.” So that billing software can accurately assign them during electronic processing.

Benefits of Medical Billing

Medical billing services also bring several benefits:

  1. It generates more revenue.
  2. It improves patient satisfaction.
  3. Referrals are other key factors.

Referrals come into play when choosing to outsource your medical billing needs. Outsourcing medical billing to an experienced medical billing provider can be helpful. You achieve revenue growth and improve your revenue cycle management.

It’s essential not only to provide exceptional service but also to make sure it’s affordable for everyone involved in the process. So there will be no hidden costs associated with this decision (such as high prices). If done correctly, this could lead directly to increased loyalty from existing customers. Besides potential ones who have yet to be introduced!

Different types of CPT codes

CPT code 77072 – Bone age study.

CPT code 81220 – CFTR gene analysis.

Knowing how much medical billing help in the CPT code is essential.

What is CPT 83605?

The  CPT 83605 can be used to report the presence of lipase in a specimen. 

83605 CPT code Description

This test is done on a patient’s arm vein blood sample. Then the sample is sent with an automated centrifuge and tested for free fatty acids (FFA). The test results determine whether an excessive level of FFA in the body needs treatment. Lipase is a digestive enzyme of the large intestine produced by the body.

Your doctor may order a chemistry test for lipase if they suspect that you have pancreatitis or cystic fibrosis. Lipase is an enzyme the body produces that helps break down fat cells in the large intestines. Lipase levels can be elevated in blood serum when there is inflammation of the pancreas gland (pancreatitis). Besides, when the pancreas has a mass, which is seen in pancreatic cancer. On the other hand, lipase can be low when there has been significant permanent damage to the pancreas cells. It can also be low in patients with cystic fibrosis.

When lipase levels are low, it can mean inflammation. It also indicates damage to your pancreas is causing this problem. Elevated levels of lipase are often seen in patients with pancreatic cancer and also in patients with cystic fibrosis.

CPT code 77072 – Bone Age Study

Bone age study is a type of medical imaging test that uses X-rays to determine the skeletal maturity of an individual. During this procedure, your child will lie on an examination table and be placed under low-dose ionizing radiation (similar to what you would experience when flying.)

A team led by your doctor will then observe the bones in their body, including those in the hand and foot bones. Doctors can use this information to determine how far along your child is in their growth spurt or how quickly they are growing up compared with others around them.

CPT code 81220 – CFTR Gene Analysis

CFTR gene analysis is done to detect mutations in the CFTR gene. This test is used to diagnose cystic fibrosis (CF). There are currently over 1,900 known mutations in the CFTR gene. The genetic tests are available at most medical laboratories and usually cost $150-$200 per test.

CPT code 002295 – Quantitative immunoglobulin A/E/G/M

CPT code 002295 is a code that’s used to report quantitative immunoglobulin A/E/G/M. This code refers to the number of antibodies in a sample and is reported as a number in International Units (IU) or International Units per milliliter.

This code can be used for tests that measure the levels of specific antibodies and help diagnose certain diseases. This test may diagnose common conditions such as rheumatoid arthritis and systemic lupus erythematosus (SLE.)

Quantitative immunoglobulins help doctors determine how well the immune system works and can be used as a diagnostic tool. Using this code means that there was an analysis of blood samples that contained an antibody level of >1 mg/mL.

CPT Code 86140

The C-reactive protein (CRP) test is a human blood test that measures the amount of inflammation in your body. It can diagnose autoimmune disorders, monitor therapy, and detect infection.

The CRP level is measured using an instrument called a nephelometer. The technician places a drop of blood on the device, which measures how long it takes for that red blood cell to clot at room temperature (this happens within seconds). A high CRP value indicates an increased risk for heart disease or other conditions, including kidney disease, arthritis, and diabetes mellitus; lower values indicate a lower risk for these conditions.

CPT code 85025

CPT code 85025 is for a complete blood count with automated platelet and WBC differential counts. This code is used for billing for the laboratory test, which includes the following:

CBC w/diff & platelets – Complete blood count with automated platelet and WBC differential counts (CBC w/diff & platelets.)

CBC w/platelets – Complete blood cell count (CBC), including white blood cells (WBC), red blood cells (RBC), hemoglobin, or hematocrit level on an automated analyzer platelet system.


The CPT code is the foundation of medical billing and describes any procedure or service performed on an individual. There are many different types of CPT codes, but most are used for procedures related to managing diseases, injuries, or conditions in people. For example, the 83605 CPT code is used for lipase evaluation.

These codes can be used by physicians, nurses, and other healthcare professionals to bill insurers directly for services rendered at their practice or hospital.CPT 83605 is the most frequently used billing code for lipase.
