Clinical Classification

Clinical Information

  • Congenital Hypothyroidism

    a condition in infancy or early childhood due to an in-utero deficiency of thyroid hormones that can be caused by genetic or environmental factors, such as thyroid dysgenesis or hypothyroidism in infants of mothers treated with thiouracil during pregnancy. endemic cretinism is the result of iodine deficiency. clinical symptoms include severe mental retardation, impaired skeletal development, short stature, and myxedema.
  • Hypothyroidism

    a syndrome that results from abnormally low secretion of thyroid hormones from the thyroid gland, leading to a decrease in basal metabolic rate. in its most severe form, there is accumulation of mucopolysaccharides in the skin and edema, known as myxedema. it may be primary or secondary due to other pituitary disease, or hypothalamic dysfunction.
  • Acquired Hypothyroidism

    hypothyroidism, the cause of which is not present at birth.
  • Transient Hypothyroxinemia

    reduced concentration of thyroid hormone(s), usually associated with a non-thyroidal illness, that resolves spontaneously.
  • Transient Hypothyroxinemia of Prematurity|Hypothyroxinemia of Prematurity|THOP|Transient Congenital Hypothyroidism

    a common, self-limiting thyroid disorder seen in preterm infants that is characterized by abnormally low serum levels of thyroxine and free thyroxine with normal serum levels of thyroid stimulating hormone.

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.

    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education

Thyroid Diseases

Your thyroid is a small, butterfly-shaped gland in the front of your neck. It makes hormones that control the way the body uses energy. These hormones affect nearly every organ in your body and control many of your body's most important functions. For example, they affect your breathing, heart rate, weight, digestion, and moods.

Thyroid diseases cause your thyroid to make either too much or too little of the hormones. Some of the different thyroid diseases include:

  • Goiter, an enlargement of the thyroid gland
  • Hyperthyroidism, which happens when your thyroid gland makes more thyroid hormones than your body needs
  • Hypothyroidism, which happens when your thyroid gland does not make enough thyroid hormones
  • Thyroid cancer
  • Thyroid nodules, lumps in the thyroid gland
  • Thyroiditis, swelling of the thyroid

To diagnose thyroid diseases, your health care provider may use a medical history, physical exam, and thyroid tests. In some cases, your provider may also do a biopsy.

Treatment depends on the problem, how severe it is, and what your symptoms are. Possible treatments may include medicines, radioiodine therapy, or thyroid surgery.

Uncommon Infant and Newborn Problems

It can be scary when your baby is sick, especially when it is not an everyday problem like a cold or a fever. You may not know whether the problem is serious or how to treat it. If you have concerns about your baby's health, call your health care provider right away.

Learning information about your baby's condition can help ease your worry. Do not be afraid to ask questions about your baby's care. By working together with your health care provider, you make sure that your baby gets the best care possible.

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
