ICD 10 CM Official Updates and Changes - 2024 Summary

There are 500+ code changes in 2024 including new, deleted, revised, and parent codes. These 2024 ICD-10-CM codes are to be used from the effective date of services from October 1, 2023, through September 30, 2024. 

New Codes  - 501 Additions

Deleted Codes - 25 Deletions

Revised Codes -  17 Revisions 

Converted to Parent Code - 25 Codes

Summary of the changes and updates

The updates include new codes, revised codes & deletions in 17 different chapters of ICD-10-CM. Changes to the Index and other revisions are also included in the updates. 

The distribution of codes and a summary of selected conditions are listed below,

Chapter 1: Infectious and parasitic diseases – 2 codes for Acinetobacter baumannii sepsis or the cause of diseases classified elsewhere.

Chapter 2: Neoplasms – 13 codes, including 10 codes for desmoid tumors. Desmoid tumors are a rare type of tumor arising in deep connective and soft tissues and often have a variable and unpredictable course. Desmoid tumors do not metastasize and are not classified as malignant. They tend to be locally aggressive, infiltrative, and destructive. They may also be known as aggressive fibromatosis. Desmoid tumors can occur in any soft or connective tissue throughout the body, but are usually categorized into four general areas: abdominal wall; extremities/shoulder and pelvic girdles/chest wall; intraabdominal/retroperitoneal/pelvic cavity; head and neck/intrathoracic.

Chapter 3: Diseases of blood and blood-forming organs and disorders involving immune mechanism – 8 codes, including codes for Sickle-cell conditions with dactylitis. Dactylitis is a severe inflammation of the fingers and toes commonly seen in infants with sickle cell anemia.

Chapter 4: Endocrine, nutritional, and metabolic diseases – 18 codes. Included are codes for insulin resistance and hypoparathyroidism.

Chapter 6: Diseases of nervous system – 24 codes. There are new codes for Lafora Body Disease, or Lafora progressive myoclonus epilepsy, which is a neurodegenerative condition caused by a glycogen metabolism disorder that results in the accumulation of abnormal glycogen aggregates called Lafora Bodies in the brain, heart, and liver. Four codes are new for chronic migraine with aura, and five codes for Parkinson’s disease with/without dyskinesia, with/without fluctuations. Parkinson’s disease (PD) is a progressive neurodegenerative disease that presents with motor symptoms such as bradykinesia with muscle rigidity, tremor, and/or postural instability, as well as non-motor symptoms such as anxiety/panic attacks, problems with executive function, and pain.

Chapter 7: Diseases of eye and adnexa – 34 codes, including new codes for sickle-cell retinopathy, muscle entrapment by site, and foreign body sensations.

Chapter 9: Diseases of circulatory system – 10 codes. Codes include codes related to tachycardia, angina, and microvascular dysfunction.

Chapter 10: Diseases of respiratory system – 7 codes. Codes include pneumonia due to Acinetobacter baumannii and lung allograft dysfunction.

Chapter 11: Diseases of digestive system – 17 codes. New codes include acute appendicitis with generalized peritonitis, small intestinal bacterial or fungal overgrowth, and short bowel syndrome.

Chapter 13: Diseases of musculoskeletal system – 36 codes specific to osteoporosis of pelvis with pathological fracture.

Chapter 14: Diseases of genitourinary system – 15 codes including recurrent and persistent immunoglobulin A nephropathy (IgAN), the most common form of glomerulonephropathy.

Chapter 15: Pregnancy, childbirth, and puerperium – 6 codes, including new codes for intrahepatic cholestasis of pregnancy (ICP), a pregnancy-specific disorder where bile acid transport in the liver is altered. This leads to a build-up of bile acid in both the maternal circulation as well as the fetal amniotic fluid.

Chapter 17: Congenital malformations – 22 codes, including specific types of craniosynostosis.

Chapter 18: Symptoms, signs, and abnormal clinical and laboratory findings – 18 codes, including codes for foreign body sensation and breast density.

Chapter 19: Injury, Poisoning – 12 codes for the toxic effect of gadolinium.

Chapter 20: External causes of morbidity – 123 codes for objects entering through a natural orifice. Examples are buttons, batteries, plastic objects, jewelry, etc.

Chapter 21: Factors influencing health status and contact with health services – 30 codes. These codes include a variety of conditions such as carrier status, history codes, and codes related to Social Determinants of Health (SDOH). The new subcategory “Caregiver’s noncompliance with patient’s medical treatment and regimen” is an example.

Conventions and General Coding Guidelines - PART 3

Continuation of PART 2

Etiology/Manifestation Convention

Certain conditions have both an underlying etiology and multiple body system manifestations due to the underlying etiology. For such conditions, the  ICD-10-CM  has a  coding convention that requires the underlying condition to be sequenced first, if applicable, followed by the manifestation. 

Wherever such a  combination exists,  there is a “use additional code” note at the etiology code,  and a “code first” note at the manifestation code. These instructional notes indicate the proper sequencing order of the codes,  etiology followed by manifestation. 

In  most cases, the manifestation codes will have in  the code  title,  “in  diseases classified elsewhere.”  Codes with this title are components of the etiology/ manifestation convention. 

There are manifestation codes that do not have  “in diseases classified elsewhere” in the title. For such codes,  there is a  “use additional code” note at the etiology code and a “code first” note at the manifestation code,  and the rules for sequencing apply.

“Code first”  and  “Use additional code” notes are also used as sequencing rules in the classification for certain codes that are not part of an etiology/ manifestation combination. 

And

The word “and” should be interpreted to mean either “and” or “or” when it appears in a title. For example, cases of  “tuberculosis of bones”, “tuberculosis of joints”  and “tuberculosis of bones and joints” are classified to subcategory  A18.0, Tuberculosis of bones and joints.

With 

The word “with” or “in” should be interpreted to mean “associated with” or “due to” when it appears in a code title,  the Alphabetic Index  (either under the main term or subterm),  or an instructional note in the Tabular  List.  

The classification presumes a causal relationship between the two conditions linked by these terms in the  Alphabetic Index or  Tabular  List.  

These conditions should be coded as related even in the absence of provider documentation explicitly linking them unless the documentation clearly states the conditions are unrelated or when another guideline exists that specifically requires a  documented linkage between two conditions  

(e.g.,  sepsis guideline for  “acute organ dysfunction that is not clearly associated with the sepsis”). 

Code Also Note

A “code also” note instructs that two codes may be required to fully describe a condition, but this note does not provide sequencing direction.  The sequencing depends on the circumstances of the encounter.

Default Codes 

A code listed next to a main term in the ICD-10-CM Alphabetic  Index is referred to as a default code The default code represents that condition that is most commonly associated with the main term or is the unspecified code for the condition. If a condition is documented in a  medical record  (for example, appendicitis) without any additional information,  such as acute or chronic, the default code should be assigned. 

Conventions and General Coding Guidelines - PART 2

Continuation of PART 1 

Includes Notes 

This note appears immediately under a three-character code title to further define, or give examples of,  the content of the category. 

Inclusion Terms

A list of terms is included under some codes. These terms are the conditions for which that code is to be used.  The terms may be synonyms of the code title, or, in the case of “other specified” codes,  the terms are a list of the various conditions assigned to that code. The inclusion terms are not necessarily exhaustive. Additional terms found only in the  Alphabetic Index may also be assigned to a code. 

Excludes Notes 

The  ICD-10-CM  has two types of excludes notes. Each type of note has a  different definition for use,  but they are all similar in that they indicate that codes excluded from each other are independent of each other. 

Excludes1 

A type1 Excludes note is pure excludes note. It means “NOT  CODED HERE!”  An  Excludes1 note indicates that the code excluded should never be used at the same time as the code above the Excludes1  note.

Excludes2 

A type 2 Excludes note represents “Not  included here.” An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time.

Code Assignment and Clinical  Criteria

The assignment of a diagnosis code is based on the provider’s diagnostic statement that the condition exists. The provider’s statement that the patient has a  particular condition is sufficient. Code assignment is not based on clinical criteria used by the provider to establish the diagnosis. 

ICD-10 CM Conventions and General Coding Guidelines - PART 1

Format and Structure

The Tabular List contains are Categories Subcategories codes.  

All categories are 3 characters. A three-character category that has no further subdivision. The Subcategories are either 4 or 5 characters. The Codes maybe 3,  4, 5,  6, or  7 characters. That is, each level of subdivision after a category is a subcategory. The final level of subdivision is a  code. 

Placeholder Character

The ICD-10-CM utilizes a placeholder character  “X”.  The “X” is used as a placeholder at certain codes to allow for future expansion. 

An example of this is at the poisoning, adverse effect, and underdosing codes, categories  T36-T50.  Where a placeholder exists, the X  must be used in order for the code to be considered a valid code

NEC - Not  Elsewhere Classifiable

NEC - This  abbreviation  in the  Alphabetic  Index & Tabular List represents “other  specified.” When a  specific code is not available for a  condition,  the  Alphabetic Index directs the coder to the “other specified”  code in the  Tabular  List. 

NOS - Not Otherwise Specified 

NOS - This abbreviation is the equivalent of unspecified. 

Punctuation

[ ] Brackets are used in the  Tabular  List to enclose synonyms, alternative wording, or explanatory phrases. Brackets are used in the  Alphabetic  Index to identify manifestation codes. 

( ) Parentheses are used in both the Alphabetic Index and Tabular List to enclose supplementary words that may be present or absent in the statement of a disease or procedure without affecting the code number to which it is assigned. The terms within the parentheses are referred to as nonessential modifiers. 

: Colons are used in the Tabular List after an incomplete term which needs one or more of the modifiers following the colon to make it assignable to a given category.

Other Specified Codes

“Other” codes Codes titled  “other”  or  “other specified”  are for use when the information in the medical record provides detail for which a specific code does not exist in the alphabetic index or Tabular list

Unspecified Codes

 “Unspecified” codes Codes  titled  “unspecified”  are for use when the information in the medical record is insufficient to assign a more specific code.

Usage of ICD 10 CM - Drive the Codes

Alphabetic Index and Tabular List

The ICD-10-CM is divided into two main part,

• Alphabetic Index 
• Tabular List

Alphabetic Index

An alphabetical list of terms and their corresponding code and contains the following parts.

• Diseases
• Injury
• External Causes of Injury
• Neoplasms Table
• Drugs and Chemicals Tables

Tabular List 

A structured list of codes divided into chapters based on body system or condition.

Drive the Codes

To select a code in the classification that corresponds to a diagnosis or reason for visit documented in a medical record.

First, locate the term in the Alphabetic Index, and then verify the code in the Tabular List.

Read thoroughly and be guided by instructional notations that appear in both the Alphabetic Index and the Tabular List.

It is essential to use both the Alphabetic Index and Tabular List when driving and assigning a code. The Alphabetic Index does not always provide the full code.

Selection of the full code, including laterality and any applicable 7th character can only be done in the Tabular List.

A dash (-) at the end of an Alphabetic Index entry indicates that additional characters are required. Even if a dash is not included at the Alphabetic Index entry, it is necessary to refer to the Tabular List to verify that no 7th character is required.

ICD-10 CM Clinical Examples for Documentation

CLINICAL DOCUMENTATION

The providers need to be specifying the anatomical location and laterality in the documentation to select the appropriate most specific ICD codes. 

There are a few examples of clinical documentation updated below and how the physicians and clinicians communicate and what they pay attention to it is a matter of ensuring the information is captured in your documentation.

In ICD-10-CM, there are three main categories of changes,

• Definition Changes
• Terminology Differences
• Increased Specificity

The expansion of ICD-10 codes is due to the addition of laterality (left, right, bilateral). Physicians and other clinicians likely already note the side when evaluating the clinically pertinent anatomical site(s).

Clinical Examples:1 - ACUTE MYOCARDIAL INFARCTION (AMI)

When documenting an AMI, include the following,

Time-frame an AMI is now considered “acute” for 4 weeks from the time of the incident.

The episode of care ICD-10 does not capture an episode of care (e.g. initial, subsequent, sequelae).

Subsequent AMI ICD-10 allows coding of a new MI that occurs during the 4 weeks “acute period” of the original AMI.

• I21.02 ST elevation (STEMI) myocardial infarction involving left anterior descending coronary artery
• I21.4 Non-ST elevation (NSTEMI) myocardial infarction
• I22.1 Subsequent ST elevation (STEMI) myocardial infarction

Clinical Examples:2 - HYPERTENSION

In ICD-10, hypertension is defined as essential (primary). The concept of “benign or malignant” as it relates to hypertension no longer exists.

When documenting hypertension, include the following,

Types Hypertension - HTN, e.g. essential, secondary, etc.

Causal relationship e.g. Renal, pulmonary, etc.

• I10 Essential (primary) hypertension
• I11.9 Hypertensive heart disease without heart failure
• I15.0 Reno-vascular hypertension

Clinical Examples:3 - ASTHMA

ICD-10 terminology used to describe asthma has been updated to reflect the current clinical classification system.

When documenting asthma, include the following,

Cause Exercise-induced, cough variant, related to smoking, chemical or particulate cause, occupational.

Severity Choose one of the three options below for persistent asthma patients

• Mild persistent
• Moderate persistent
• Severe persistent

Temporal Factors Acute, chronic, intermittent, persistent, status asthmatics,  acute exacerbation,

• J45.30 Mild persistent asthma, uncomplicated
• J45.991 Cough variant asthma

Clinical Examples:4 - UNDER-DOSING

Underdosing is an important new concept and term in ICD-10. It allows you to identify when a patient is taking less of a medication than is prescribed.

When documenting underdosing, include the following,

Intentional, Unintentional, Non-compliance Is the underdosing deliberate? (e.g., patient refusal).

Reason Why is the patient not taking the medication? (e.g.financial hardship, age-related debility).

• Z91.120 Patient’s intentional underdosing of medication regimen due to  financial hardship
• T36.4x6A Underdosing of tetracyclines, initial encounter
• T45.526D Underdosing of antithrombotic drugs, subsequent encounter

Clinical Examples:5 - DIABETES MELLITUS, HYPOGLYCEMIA, AND HYPERGLYCEMIA

The diabetes mellitus codes are combination codes that include the type of diabetes mellitus, the body system affected, and the complications affecting that body system. When documenting diabetes, include the following,

Type e.g. Type 1 or Type 2 disease, drug or chemical induces, due to underlying condition, gestational.

Complications What (if any) other body systems are affected by the diabetes condition? e.g. Foot ulcer related to diabetes mellitus.

Treatment Is the patient on insulin?.

A second important change is the concept of “hypoglycemia” and “hyperglycemia.” It is now possible to document and code for these conditions without using “diabetes mellitus.”  The provider can also specify if the condition is due to a procedure or other cause.

The final important change is that the concept of “secondary diabetes Mellitus” is no longer used; instead, there are specific secondary options.

• E08.65 Diabetes Mellitus due to underlying condition with hyperglycemia
• E09.01 Drug or chemical induced diabetes Mellitus with  hyperosmolarity with coma
• R73.9 Transient post-procedural hyperglycemia
• R79.9 Hyperglycemia, unspecified

Clinical Examples:6  ABDOMINAL PAIN AND TENDERNESS

When documenting abdominal pain, including the following,

Location e.g. Generalized, Right upper quadrant, periumbilical, etc.

Pain or tenderness type e.g. Colic, tenderness, rebound

• R10.31 Right lower quadrant pain
• R10.32 Left lower quadrant pain
• R10.33 Periumbilical pain

New ICD codes for COVID-19

In March 2020 the Novel Coronavirus Disease, COVID-19, was declared a pandemic by the World Health Organization.

The Centers for Disease Control (CDC), under the National Emergencies Act Section 201 and 301, is announcing further additions to the ICD-10-CM Classification related to COVID-19, which will become effective January 1, 2021.

As a result of the ongoing COVID-19 public health emergency, the Centers for Disease Control and\ Prevention’s National Center for Health Statistics (CDC/NCHS) is implementing additional codes into ICD-10-CM for reporting to include,

• Encounter for screening for COVID-19  - Z11.52
• Contact with and (suspected) exposure to COVID-19 - Z20.822
• Personal history of COVID-19 - Z86.16
• Multisystem inflammatory syndrome (MIS) - M35.81
• Other specified systemic involvement of connective tissue - M35.89
• Pneumonia due to coronavirus disease 2019 - J12.82
• COVID-19 Positive - U07.1

These new codes will be effective January 1, 2021, to identify conditions resulting from COVID-19.
