ICD 10 Codes and How to Look Them Up

The right code ensures you're correctly treated and billed

International Classification of Diseases (ICD) codes are a set of designations used by healthcare staff to communicate diseases, symptoms, abnormal findings, and other elements of a patient's diagnosis in a way that is universally accepted by those in the medical and insurance fields. The tenth and most recent edition is known as ICD-10.

ICD-10 codes are passed to insurance companies to establish the medical necessity of the services a provider is asking to be paid for. There are more than 70,000 of them, and their highly specific definitions are understood by all who use them.

While ICD-10 codes often appear on patient paperwork and bills, they don't always. Looking up these codes can become quite important if you're trying to sort out a medical pre-approval or billing issue with your insurance provider. An incorrect code can mean that coverage of practitioner visits and treatments gets denied.

This article explains how medical professionals use ICD codes, why they matter to you, and how you can find an ICD-10 when you need it.

How to Look Up ICD-10 Codes

You may want to look up an ICD code because:

• Your insurance claim is being disputed
• Your insurance claim has not been paid
• You have submitted for pre-approval for a certain treatment or specialist visit and were denied

This sometimes happens when an ICD code does not align with a CPT code, which is similar designation that identifies the services rendered or being requested.

You may be able to find ICD-10 codes for a recent visit by checking out the summary given to you by your healthcare provider or hospital. ICD codes should be listed under "diagnosis" or "Dx."

Explanation of benefits (EOB) statements from your insurance company, Medicare, or another payer may also contain ICD codes.

If you need to look up the ICD code for a particular diagnosis or confirm what an ICD code stands for, visit the Centers for Disease Control and Prevention (CDC) website to use their free searchable database of current ICD-10 codes.

Having ICD-10 codes on-hand—both the correct ones for your situation and those that were filed in your case, if different—can help you have a more productive conversation with your provider, their billing department, and your insurance company.

How ICD Codes Are Used

ICD codes are used in billing, treatments, and statistics collection. Having the right code is important to ensure that standardized treatment for a medical issue is delivered and that medical expenses are reimbursed.

In the United States, ICD codes are overseen by the Centers for Medicare and Medicaid Services (CMS) and the National Center for Health Statistics (NCHS). 

The ICD receives annual updates in between revisions, which is sometimes reflected in the code title. For example, the 2020 updated version was the ICD-10-CM. The ICD-11 was approved by the WHO in 2019 so it can go into effect in 2022.

The ICD is maintained by the World Health Organization (WHO) and used across the globe, with some country-specific modifications.

Insurance Reimbursement

When your healthcare provider submits a bill to an insurance company for reimbursement , each service is described by a common procedural technology (CPT) code . It is matched to an ICD code. If the two codes don't align correctly with each other, the company may deny payment.

In other words, if the service isn't one that would typically be provided for someone with that diagnosis, an insurance company will not pay.

For example, your healthcare provider should not submit a bill for an X-ray if you come in complaining of a rash since imaging is not indicated for that concern.

Disease Management

An ICD code is assigned to every disease. If you have a chronic illness, such as diabetes or heart disease, your ICD code will typically follow your medical records.

In a hospital setting, this can be lifesaving. But for patients with chronic conditions who come to the hospital for an unrelated issue, this can cause frustration.

When you meet a new healthcare provider, they may ask questions about the chronic illness first instead of focusing on your reason for being in the hospital. However, while a condition may seem unrelated to you, there may be a connection known only to the physician.

This process makes sense when you consider that about 80% of "older adults" have at least one chronic health condition while 50% have two or more.

Still, this reality sometimes results in a provider ordering unnecessary tests and treatments that are indicated for the chronic condition rather than focusing on the concern that caused you to seek treatment.

ICD codes are used globally to track health statistics and causes of death. This is helpful for gathering data on chronic illnesses as well as new ones. For example, a new code was added to the ICD-10 in 2020 to track vaping-related illnesses .

ICD codes are also used in clinical trials to recruit and track subjects and are sometimes, though not always, included on death certificates.

Elements of ICD-10 Codes

The ICD-10 update in 2015 completely overhauled the coding system. The new codes are broken down into chapters and subchapters. They include a letter plus two digits to the left of the decimal point, then one or two digits to the right.

The letters group diseases together and describe a specific condition, organ system, or characteristic of a condition. The numbers further refine that definition.

For example, E10.9 stands for type 1 diabetes and E11.9 is type 2 diabetes.

The letter is determined by the nature of the diagnosis:

• A: Infectious and parasitic diseases
• B: Infectious and parasitic diseases
• D: Neoplasms, blood, and blood-forming organs
• E: Endocrine, nutritional, or metabolic
• F: Mental and behavioral disorders
• G: Nervous system
• H: Eyes, ears, nose, and throat
• I: Circulatory system
• J: Respiratory system
• K: Digestive system
• M: Musculoskeletal system
• N: Genitourinary system
• O: Pregnancy and childbirth
• P: Perinatal conditions
• Q: Congenital and chromosomal abnormalities
• R: Abnormal clinical and lab findings
• S: Injury, poisoning, and other external causes
• T: Injury, poisoning, and other external causes
• U: Used for emergency designation
• V: External causes of morbidity
• W: External causes of morbidity
• X: External causes of morbidity
• Y: External causes of morbidity
• Z: Factors influencing health status and contact with health services

Updating ICD-10 Codes

In 2022, the ICD codes will change again with the addition of two numbers—one that precedes the letter and one that comes at the end. For example, X98.6 (ICD-10 code) will become 0X98.60.

The updated code also does not use letters "I" or "O" to avoid confusion with 1 and 0.

This new edition will be called ICD-11.

The International Classification of Diseases (ICD) is a tool that assigns codes—a kind of medical shorthand—for diseases, signs and symptoms, abnormal findings, circumstances, and external causes of diseases or injury. Insurance companies expect the codes to be consistent between a condition and the treatment rendered. Otherwise, they may balk at paying. This is reason enough to learn how to look them up for yourself.

What ICD-10 Codes are Used for Lab Review

Regarding lab review in the medical field, several ICD-10 codes are commonly used to describe various clinical scenarios and conditions that may require laboratory tests and analysis. These codes help healthcare professionals accurately document and bill for the services provided during lab reviews. Here are the commonly used Lab Review ICD-10 codes , along with clinical descriptions for each code:

• R73.01 - Abnormal glucose: This code is used when a patient's blood glucose levels are outside the normal range, indicating potential issues such as diabetes or prediabetes, which often require further lab review and diagnostic testing.
• R74.0 - Abnormal serum enzyme levels: When lab results show elevated or abnormal levels of serum enzymes, it can be a sign of various medical conditions, such as liver disease or muscle injury, necessitating further lab review for a precise diagnosis.
• R82.5 - Proteinuria: Proteinuria indicates an abnormal amount of protein in the urine, which can be a sign of kidney disease, among other conditions. Lab reviews are essential for determining the underlying cause.
• D49.9 - Neoplasm of unspecified behavior of the endocrine glands: This code is used when lab results suggest the presence of an endocrine gland tumor, but further testing is required to determine whether it is benign, malignant, or uncertain.
• E03.9 - Hypothyroidism, unspecified: Hypothyroidism affecting the thyroid gland may require a lab review to diagnose the condition's severity and guide treatment decisions.
• R07.9 - Chest pain, unspecified: Lab tests may be conducted in chest pain cases to rule out severe cardiac conditions or to identify other causes, such as muscle strain or anxiety.
• N18.9 - Chronic kidney disease, unspecified: Lab review is crucial for diagnosing and staging chronic kidney disease, which can have various causes and complications.
• D72.829 - Eosinophilia, unspecified: Elevated eosinophil levels in blood tests can indicate various underlying conditions, including allergies, infections, or autoimmune diseases, requiring further investigation.
• R55 - Syncope and collapse: Lab work may be necessary to identify the underlying causes of syncope (fainting) and collapses resulting from heart issues, neurological problems, or other conditions.
• Z13.6 - Encounter for screening for cardiovascular disorders: This code is used when patients undergo lab reviews as part of routine cardiovascular screening, such as lipid profile testing, to assess their risk of heart disease.

Family physicians are frequently asked to perform pre-surgical evaluations, both in the office and at the hospital. The Centers for Medicare & Medicaid Services recently proposed no longer requiring a comprehensive medical history and physical assessment prior to surgery, but many patients will still need an evaluation and many surgeons will still request one.

Physicians must select a CPT code and a diagnosis code for the evaluation. This is typically done in the office for scheduled procedures and in the hospital for urgent or emergency surgery.

CPT codes. If the evaluation meets the requirements for a consultation, and if the patient’s insurance company still recognizes consultation codes (many commercial payers still do), you can bill a consult. Consult codes most accurately describe the service performed and are reimbursed at a higher rate than new and established patient visit codes. According to CPT, “A consultation is a type of evaluation and management service provided at the request of another physician or appropriate source to either recommend care for a specific condition or problem or to determine whether to accept responsibility for ongoing management of the patient’s entire care or for the care of a specific condition or problem.” Use outpatient codes 99241-99245 or inpatient codes 99251-99255 for new or established patients.

Like most evaluation and management codes, consultation codes have different levels that require performance and documentation of a certain level of history, exam, and medical decision-making as part of the encounter. If you perform and document the key components, and if the medical record reflects the request for evaluation and that you returned a report to the requesting physician, you should have no difficulty reporting a consultation code for the encounter, as long as the payer accepts consultation codes.

Medicare and Medicare Advantage plans do not recognize consult codes. State Medicaid programs and Managed Medicaid plans can also set their own rules and may not recognize consult codes. For these patients seen in the office, bill a new or established patient office visit code (99201-99205 or 99211-99215), and for inpatients bill the appropriate hospital care code. You can typically bill an initial hospital service (99221-99223). The admitting physician typically uses an AI modifier (Principal Physician of Record) on the initial hospital care code to indicate that he or she is the admitting physician, and consultants typically use the initial hospital care code with no modifier.

Diagnosis codes. For the diagnosis, use a code from subcategory Z01.81-, “Encounter for preprocedural examinations,” based on the co-morbidities you are assessing:

• Z01.810, “Encounter for preprocedural cardiovascular examination.”

• Z01.811, “Encounter for preprocedural respiratory examination.”

• Z01.812, “Encounter for preprocedural laboratory examination.”

• Z01.818, “Encounter for other preprocedural examination.”

Most pre-op exams will be coded with Z01.818. The ICD-10 instructions say to use the preprocedural diagnosis code first, and then the reason for the surgery and any additional findings.

Evaluations before surgery are reimbursable services. Select the type of service – established visit, consult, initial hospital care, etc. – and the reason for the visit in order to get paid.

When is it proper to bill nurse visits using 99211.

by   Christine Woolstenhulme, QMC QCC CMCS CPC CMRS Sep 28th, 2021 - Reviewed/Updated Aug 29th

When vaccines or injections are given in the office, coding can often get confusing; for example, is it correct to report a nurse visit using  99211  and an E/M office visit reporting  99202  ‑  99215  and include injection fees with the vaccine product? In addition, the reporting of evaluation and management (E/M) during the same visit where vaccines are administered is not always understood. The answer depends on whether the provider performs a medically necessary and significant, separately identifiable E/M visit, in addition to the immunization administration.

CMS states, when a separately identifiable E/M service (which meets a higher complexity level than CPT code  99211 ) is performed, in addition to drug administration services, you should report the appropriate E/M CPT code reported with modifier -25. Documentation should support the level of E/M service billed. For an E/M service provided on the same day, a different diagnosis is not required.

It is incorrect to bill a  99211  when the provider provides an E/M service that meets a higher complexity level than CPT code  99211 , you must bill the higher complexity, and you cannot bill for two services in one day. 

Charging for Nurse Visits

There are times when it is appropriate to report for a nurse visit using CPT code  99211 . The  Incident-to rule  applies when reporting this code, and services provided must be documented as medically necessary services, including the clinical history, clinical exam, making a clinical decision, and physician supervision. 

• NOTE: A nurse visit is not paid if billed with a drug administration service such as chemotherapy or non-chemotherapy drug infusion code, including therapeutic or diagnostic injection codes. The reasoning is because diagnostic IV infusion or injection services typically require direct physician supervision, and using  99211 is reported by qualified healthcare professionals other than physicians.

08/29/2023 NOTE: (These CPT codes,90782, 90783, 90784, or 90788  were deleted in 2006, but still showing in CMS - Claims processing manual) When reporting CPT codes 90782, 90783, 90784, or 90788 , CPT code 99211  cannot be reported. In addition, it is improper billing to report a visit solely for an injection that meets the definition of the injection codes. 

When the only reason for the visit is for the patient to receive an injection, payment may be made only for the injection (if it is covered). An office visit using  99211 would not be warranted where the services rendered did not constitute a regular office visit and a part of the plan of care and not at the patient's request.

Unlike other E/M codes  99202 - 99205 , and 99212 - 99215 , time alone cannot be used when reporting  99211  when selecting the appropriate code level for E/M services. Effective January 1, 2021, time was removed as an available code-selection criterion. The typical time spent on this code is five minutes.  

Other visits billed with  99211

Several other visits may be reported using  99211 , and nurses are not the only staff that can report this code; medical Assistants and technicians are also included under non-physician.  

Covid-19 Testing

According to  CMS ; Physician offices can use CPT code  99211  when office clinical staff furnish assessment of symptoms and specimen collection for Covid-19 incident to the billing professionals services for both new and established patients. When the specimen collection is performed as part of another service or procedure, such as a higher-level visit furnished by the billing practitioner, that higher-level visit code should be billed. The specimen collection would not be separately payable.

Examples from CMS

The following are examples of when  CPT  99211  might be used:

• Office visit for an established patient for blood pressure check and medication monitoring and advice. History, blood pressure recording, medications, and advice are documented, and the record establishes the necessity for the patient's visit.
• Office visit for an established patient for return to work certificate and advice (if allowed to be by other than the physician). Exam and recommendation are noted, and the Return to Work Certificate is completed, copied, and placed in the record.
• Office visit for an established patient on regular immunotherapy who developed wheezing, rash, and swollen arm after the last injection. Possible dose adjustments are discussed with the physician, and an injection is given. History, exam, dosage, and follow-up instructions are recorded.
• Office visit for an established patient's periodic methotrexate injection. Monitoring Lab tests, query signs and symptoms, obtain vital signs, repeat testing, and injection advised. All this information is recorded and reviewed by the physician. (Note that in this circumstance, if  99211  is billed, the injection code is not separately billable). An office visit for an established patient with a new or concerning bruise is checked by the nurse (whether or not the patient is taking anticoagulants), and the patient is advised on how to care for the bruise and what to be concerned about, and, if on anticoagulants, continuing or changing current dosage is advised. History, exam, dosage, and instructions are recorded and reviewed by the physician.
• Office visit for an established patient with atrial fibrillation who is taking anticoagulants and has no complaints . The patient is queried by the nurse, vital signs are obtained, the patient is observed for bruises and other problems, the prothrombin time is obtained, the physician is advised of prothrombin time and medication dose, and medication is continued at present dose with follow up prothrombin time in one month recommended. History, vital signs, exam, prothrombin time, INR, dosage, physician's decision, and follow-up instructions are recorded.
