Navigating the 2025 ICD-10-CM Revisions with Cliniqon

September 2024

On October 1, 2024, the latest ICD-10-CM revisions from the Centers for Medicare & Medicaid Services (CMS) will come into effect for FY 2025. These updates include significant changes across various medical categories such as the introduction of new codes, modifications to existing codes, and removal of outdated entries. The annual revisions to the ICD-10-CM code set reflect ongoing efforts to enhance the granularity and specificity of medical coding, which is crucial for accurate diagnosis, treatment, and billing processes.

Key Changes in the 2025 ICD-10-CM Revisions


The updates introduce 252 new ICD-10-CM codes, 36 code deletions, and 13 revisions. Here are some of the key changes:

Neoplasms: New codes have been added for different types of lymphoma in remission, expanding the ability to code for conditions like Nodular Sclerosis Hodgkin Lymphoma, and Cutaneous Follicle Center Lymphoma in remission.

Endocrine, Nutritional, and Metabolic Disorders: New codes are available for different levels of hypoglycemia and obesity classes, providing more detailed reporting options. The new codes now include classifications for presymptomatic type 1 diabetes, adding more specificity to diabetic conditions.

Mental Health: Under F50 Eating disorders there are several new codes for anorexia nervosa, restricting type (F50.010-F50.019), binge eating/purging type (F50.020-F50.029), bulimia nervosa (F50.20-F50.25), and binge eating disorder (F50.810-F50.819). Also new are F50.83 Pica in adults and F50.84 Rumination disorder in adults.

Nervous System: There are several changes under G40 Epilepsy and recurrent seizures including the addition of G40.84 KCNQ2-related epilepsy and four child codes (G40.841-G40.844) to specify whether or not the disease is intractable, with status epilepticus. There are also new codes for serotonin syndrome (G90.81), other disorders of the autonomic nervous system (G90.889), and developmental and epileptic encephalopathy (G93.45).

Infections: A new Z code has been introduced for encounters related to aftercare following sepsis, which will help in more accurate tracking and management of post-sepsis care.

Respiratory System: Under subcategory J21 Acute bronchiolitis there are several new codes for nasal valve collapse. The sixth-character codes specify the location of the collapse (internal/external) and the seventh-character codes describe the state of the condition (static/dynamic/unspecified).

Musculoskeletal and connective tissue: There are several new codes for diseases of the musculoskeletal system and connective tissue. Under M51 Thoracic, thoracolumbar, and lumbosacral intervertebral disk disorders, there are new six-character codes that allow the practitioner to specify the location of pain more succinctly. Under subcategory M65 Synovitis and tenosynovitis, several fifth- and sixth-character codes are added to allow the practitioner to specify the location of the unspecified synovitis and tenosynovitis.

Importance of Adapting to the ICD-10-CM Changes for Home Health Providers

Adapting to the new ICD-10-CM changes is critical to ensure accurate billing, avoid claim denials, and maintain compliance with regulatory standards. Updated codes enable providers to deliver precise care. Failure to adapt can lead to financial penalties, disrupted cash flow, and potential legal issues, all of which could harm the provider’s reputation and operational efficiency.
