Hypothyroidism has several types and corresponding unique ICD-10 codes, so many health practitioners and medical coders bear up their shoulders with this.
The wrong ICD-10 hypothyroidism code may lead to denials of claims and delays in reimbursement. Hence, one ought to code Hypothyroidism well to be safe in these circumstances.
At Health Med Affairs, we know how vital accurate coding is for a smooth revenue cycle. That’s why we help healthcare providers code more efficiently.
Below, we will cover everything you need to know about hypothyroidism ICD-10 codes, including “What is the hypothyroidism ICD-10 in medical billing?” Learn when to use them and how to avoid mistakes.
What Is Hypothyroidism?
Hypothyroidism is a health issue that results from a lack of the necessary thyroid hormones produced by the gland.
A tiny butterfly-shaped thyroid gland found in your neck is crucial for your body. It directs metabolism, energy output, body temperature, and heart frequency.
When this gland dims its light, your whole system can snooze. This condition knows no age limits but prefers to dance with women, especially those gracefully embracing their 60s and beyond.
Common Symptoms of Hypothyroidism
A patient experiencing low thyroid function might report several varied symptoms.
- Fatigue
- Weight gain
- Cold intolerance
- Slow heart rate
- Constipation
- Dry skin
- Depression
- Memory problems
- Thinning hair
- Puffy face
Since these symptoms build up gradually, the condition might be ignored.
Causes of Hypothyroidism
Understanding the cause of Hypothyroidism is essential, not just for treatment but also for coding purposes. Some of the common causes include:
- Hashimoto’s thyroiditis (autoimmune)
- Iodine deficiency
- Thyroid surgery
- Radiation therapy
- Certain medications (like lithium or amiodarone)
- Congenital thyroid disorders
- Pituitary gland dysfunction
Every reason might result in a distinct diagnosis of hypothyroidism ICD-10 code, and that’s where Health Med Affairs can assist you in remaining accurate and compliant.
Why Accurate Hypothyroidism ICD-10 Coding Matters?
Medical billing depends heavily on the ICD code for Hypothyroidism, which helps describe a patient’s diagnosis in a standardized format. Using the wrong code, or a vague one, can lead to:
- Denied claims
- Delays in reimbursement
- Incorrect patient records
- Compliance issues
For Hypothyroidism, using a specific ICD-10 code is critical. It’s vital to determine a unique code for Hypothyroidism.
The E03.9 diagnosis code acts as the standard code for unclear Hypothyroidism, although it’s better to employ a code that matches the specific kind or cause whenever possible.
What Is the Hypothyroidism ICD-10 in Medical Billing?
Let’s start with the most common code:
The main billable ICD-10 code is E03.9, for “Hypothyroidism, unspecified.” Use this code when details are unclear. E03.9 is billable, but using a specific code is often better. It improves disease classification and helps with insurance claims. At Health Med Affairs, our team uses this only when the patient’s records don’t provide enough detail to use a more precise code.
Types of Hypothyroidism and Their ICD-10 Codes
Some of the different forms of Hypothyroidism, their causes, and their ICD-10 codes for Hypothyroidism are presented below.
- Subclinical Hypothyroidism
ICD-10 Code: E02
This initial kind of Hypothyroidism has an increased TSH but normal T3 and T4, like many of its early stages. It can be harmless, even if it sometimes requires monitoring and treatment.
2. Hashimoto’s Thyroiditis (Autoimmune Hypothyroidism)
ICD-10 Codes: E06.3 (Autoimmune thyroiditis), E03.9 (Hypothyroidism, unspecified)
An autoimmune disorder, it is the top cause of Hypothyroidism in the United States. The immune system attacks thyroid tissue, leading to slow gland failure.
3. Acquired Hypothyroidism Due to Thyroid Atrophy
ICD-10 Code: E03.4
Occurs when the thyroid tissue begins to shrink due to continuous autoimmune reactions or ageing.
4. Post-Surgical (Postprocedural) Hypothyroidism
ICD-10 Code: E89.0
Occurs following surgical or partial thyroid gland removal, such as after thyroidectomy.
5. Secondary Hypothyroidism (Pituitary Origin)
ICD-10 Code: E23.0
Results from reduced stimulation of the thyroid due to pituitary gland dysfunction. Unlike primary Hypothyroidism, the thyroid itself is intact.
6. Other Specified Types of Hypothyroidism
ICD-10 Code: E03.8
Engaged when a patient presents with a distinctly classified yet lesser-known version of Hypothyroidism not accounted for by other codes.
7. Congenital Hypothyroidism
ICD-10 Code: E03.1
This condition is present at birth. It results from an absent, underdeveloped, or malfunctioning thyroid gland. Early diagnosis is essential to prevent developmental delays in affected individuals.
8. Iodine-Deficiency Related Hypothyroidism
ICD-10 Codes: E01.8 / E02
Low iodine intake impairs thyroid hormone production.
- Use E01.8 for general iodine-deficiency disorders
- Use E02 for subclinical forms due to iodine deficiency
9. Drug-Induced Hypothyroidism
ICD-10 Code: E03.2
Medications such as lithium and amiodarone may affect the operation of hormone-releasing thyroid glands. The result of all this may be Hypothyroidism.
Additional Hypothyroidism-Related ICD-10 Codes
Sometimes, you may not be treating Hypothyroidism directly, but you still need to code for its presence:
- Z83.3: Family History of Hypothyroidism
Use this if a patient has a family history of Hypothyroidism but is not currently diagnosed.
2. Z90.89: Personal History of Thyroid Surgery
This code may be used along with E89.0 for any patient who has undergone prior thyroid surgery that resulted in Hypothyroidism.
Hypothyroidism in Pregnancy ICD-10 Code
Pregnancy complicates Hypothyroidism. Thyroid hormones are fundamental for fetal progression. The correct coding indicates that both conditions coexist: the endocrine condition and pregnancy.
There is a specific code set needed for pregnancy and Hypothyroidism. Use O99.280 and E03.9 together.
This coding accurately documents Hypothyroidism in pregnancy, ICD-10, and is very important for clinical and billing purposes.
Software Guidelines on Hypothyroidism
- Be Specific
For Hypothyroidism, please use specific ICD-10 codes for low thyroid or the precise condition in cases where this is applicable.
- Use Additional Codes Whenever Indicated
Wherever the patient’s Hypothyroidism is responsible for causing other conditions, such as depression, fatigue, or infertility, these should be documented as secondary diagnosis codes.
- Link to the Cause
Link the Hypothyroidism to its cause whenever possible: autoimmune, post-surgical, drug-induced, or secondary to pituitary failure.
- Watch for Updates
ICD-10 codes are updated annually. Ensure that you are using the latest edition to maintain compliance.
Tips for Accurate Hypothyroidism Billing
Review Lab Results: Check for TSH, T3, and T4 levels to help determine the severity or type.
Check Patient History: Look for details such as:
- Surgery
- Radiation
- Medication
Include Comorbid Conditions: Hypothyroidism can impact mental health, fertility, and cardiovascular health.
Use precise documentation to avoid mistakes.
Partner with professionals like Health Med Affairs to reduce errors and increase reimbursements.
Final Thought: What is the Hypothyroidism ICD-10 in Medical Billing?
Getting ICD-10 codes right for Hypothyroidism is not just about rules but also ensuring patients receive the care they need and insurance coverage.
Correct coding helps the provider or medical biller ensure that claims against insurance are processed smoothly and that patients have accurate records.
The commonly applied ICD-10 code for Hypothyroidism, unspecified, is E03.9, but it is always best to dig deeper into the patient’s history, symptoms, and lab results. This way, one might find an even better ICD-10 code that improves documentation, reduces denials, and gets reimbursement done correctly.

FAQs
Q: What is the ICD-10 code for acquired Hypothyroidism?
According to ICD-10, all acquired hypothyroidisms are coded under E03 and, more specifically, under given causes. For unspecified acquired Hypothyroidism, E03.9 should be filed.
Q: Is ICD code E03.9 used for all types of Hypothyroid conditions?
It is best to describe the condition whenever possible, while E03.9 is universal. For this reason, the other codes under E03 should also be used if documentation permits.
Q: Can I use more than one ICD-10 code for a disorder of the thyroid?
Yes. For example, suppose a pregnant woman has Hypothyroidism; in this case, we apply both E03.9 + O99.280.
