2024 ICD-10-CM Codes Summary
The distribution of codes and a summary of selected conditions is 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.
