Secondary Hypothyroidism ICD-10-CM Codes

What ICD-10 Codes are Used for Secondary Hypothyroidism?

Secondary hypothyroidism is a medical condition where the pituitary gland does not produce adequate thyroid-stimulating hormone (TSH) levels. This deficiency affects the functioning of the thyroid gland, leading to various symptoms and complications. For an accurate diagnosis and effective treatment planning, healthcare providers use specific ICD-10 codes. Here are some of the most frequently utilized ICD-10 codes for secondary hypothyroidism, along with their clinical descriptions:

1. E03.8 - This code is designated for 'Other specified hypothyroidism.' It includes various forms of hypothyroidism, one of which could be secondary hypothyroidism, provided it is explicitly mentioned in the patient's medical records. This code helps healthcare providers categorize cases that do not fall under the more common forms of hypothyroidism.

2. E03.2 - The code E03.2 stands for 'Hypothyroidism due to medicaments and other exogenous substances.' It is used when secondary hypothyroidism arises as a side effect of certain medications or exposure to external substances.

3. E03.9 - This code signifies 'Hypothyroidism, unspecified.' It is typically applied when the specific type of hypothyroidism is not explicitly mentioned in the patient's medical records. However, it can also cover cases of secondary hypothyroidism.

4. E89.0 - This code is assigned for 'Postprocedural hypothyroidism.' It is applicable when hypothyroidism, including secondary hypothyroidism, occurs following a surgical procedure or medical treatment that may have affected the thyroid or pituitary gland.

5. E02 - Known as 'Subclinical iodine-deficiency hypothyroidism,' this code is used when a deficiency of iodine leads to mild or early-stage hypothyroidism. In some cases, this can lead to secondary hypothyroidism.

6. E01.2 - Code E01.2, 'Iodine-deficiency-related multinodular (endemic) goiter,' is used when an iodine deficiency forms multiple nodules in the thyroid. This can occasionally cause secondary hypothyroidism.

Clinical Information

Secondary hypothyroidism is a complex endocrine disorder primarily caused by problems in the pituitary gland. Here are some important clinical details:

• The disorder is caused by the pituitary gland's failure to produce sufficient Thyroid Stimulating Hormone (TSH), which controls the production of thyroid hormones.
• A deficiency in TSH disrupts the balance of thyroid hormones, leading to secondary hypothyroidism.
• Symptoms can be varied and subtle, including chronic fatigue, unexpected weight gain, mood swings leaning towards depression, and increased sensitivity to cold.
• These symptoms are not exclusive to secondary hypothyroidism and can be seen in other medical conditions, making comprehensive clinical examination and specific diagnostic tests crucial for accurate diagnosis.
• Triggers for secondary hypothyroidism can include pituitary tumors, certain medications, or damage to the pituitary gland from surgery or radiation therapy.
• Pituitary tumors, usually benign, can disrupt the gland's normal functioning. Certain medications can interfere with the gland's ability to produce TSH. Damage to the pituitary gland from surgery or radiation can also lead to secondary hypothyroidism.
• An in-depth understanding of these clinical aspects is vital for healthcare providers and patients to manage this condition effectively.

Synonyms Include:

• Pituitary hypothyroidism
• Central hypothyroidism
• Tertiary hypothyroidism
• Hypothyroidism due to pituitary disease
• Hypothyroidism due to hypothalamic disorder
