List of ICD-9 codes 240–279: endocrine, nutritional and metabolic diseases, and immunity disorders

The List of ICD-9 codes 240–279 includes a wide range of endocrine, nutritional, metabolic diseases, and immunity disorders. These codes are used to classify and categorize various conditions related to the endocrine system, such as disorders of the thyroid, adrenal glands, and pituitary gland, as well as diseases related to metabolism, nutrition, and immune system dysfunction.

Here are some examples of conditions covered by these codes:

1. Thyroid disorders: This includes conditions such as hypothyroidism (ICD-9 code 244), hyperthyroidism (ICD-9 code 242), and goiter (ICD-9 code 240).

2. Diabetes mellitus: This category includes codes for both type 1 (ICD-9 code 250.01) and type 2 (ICD-9 code 250.00) diabetes, as well as codes for complications of diabetes, such as diabetic retinopathy (ICD-9 code 250.5) and diabetic neuropathy (ICD-9 code 250.6).

3. Disorders of calcium metabolism: This includes conditions such as hypercalcemia (ICD-9 code 275.42) and hypocalcemia (ICD-9 code 275.41).

4. Disorders of lipid metabolism: This category includes codes for conditions such as hyperlipidemia (ICD-9 code 272.4) and hypercholesterolemia (ICD-9 code 272.0).

5. Nutritional deficiencies: This includes codes for conditions such as vitamin D deficiency (ICD-9 code 268.9) and iron deficiency anemia (ICD-9 code 280.9).

6. Immune system disorders: This category includes codes for conditions such as primary immunodeficiency disorders (ICD-9 code 279.0) and autoimmune diseases like rheumatoid arthritis (ICD-9 code 714.0) and systemic lupus erythematosus (ICD-9 code 710.0).

These codes are used by healthcare professionals for accurate diagnosis, treatment, and billing purposes. It is important to note that the ICD-9 coding system has been replaced by the ICD-10 system, which provides more detailed and specific codes for these conditions.
