Thyroidectomy ICD-10-CM Codes

What ICD-10 Codes are Used for Thyroidectomy 

There are no specific thyroidectomy ICD codes you can use. However, you can employ the following thyroidectomy-related ICD-10 codes:

• T81.40XA - Infection following a procedure, unspecified, initial encounter

This ICD-10 code is meant to be used on a person confirmed to have an infection after undergoing a procedure. It’s unspecified as to what procedure. Given this, this can be used on patients who have infections that emerged after a thyroidectomy. The initial encounter label means that the patient is receiving active treatment for it.

• T81.40XD - Infection following a procedure, unspecified, subsequent encounter

This is the same as Item 1, but this time, there is a subsequent encounter label. This means that the patient is in the recovery phase for the infection they sustained and they are still being given active care for it.

• T81.40XS - Infection following a procedure, unspecified, sequela

This is the same as Item 1, but this time, there is a sequela label. This means that the patient is dealing with the aftereffects of the infection, so this code should be accompanied by two other ICD-10 codes, one of which should specify the sequela’s nature and the other describing its effects on the patient.

• E89.2 - Postprocedural hypoparathyroidism

This ICD-10 code is meant to be used on a patient confirmed to have hypoparathyroidism as a result of a procedure, so if a patient of yours gets this after a thyroidectomy, you can use this.

• Z90.09 - Acquired absence of other part of head and neck

This ICD-10 code is meant to be used on a patient confirmed to have a missing part of their head and/or neck. In the context of this topic, they’re missing a thyroid because of a procedure.

Are these thyroidectomy ICD codes billable?

Yes. The aforementioned ICD-10 codes are valid and billable.

Clinical information about thyroidectomy

• Thyroidectomy is a surgical procedure involving removing part or all of the thyroid gland.
• The thyroid gland, a part of the endocrine system, is located in the front part of the neck. Its primary function is to produce hormones that regulate the body's metabolism.
• There are several reasons for a thyroidectomy, including thyroid cancer, noncancerous enlargement of the thyroid (goiter), and overactive thyroid (hyperthyroidism).
• The procedure can be performed as a total thyroidectomy, where the entire gland is removed, or a partial thyroidectomy, where only a part of the gland is taken out.
• Post-surgery, patients may need to take thyroid hormone medication to replace the hormones the thyroid would normally produce.
• Potential complications of a thyroidectomy include voice changes, difficulty swallowing, low calcium levels, and, rarely, damage to the surrounding nerves and glands.
• Recovery time can vary, but most individuals can return to normal activities within a couple of weeks following the procedure.

Synonyms include:

• Postoperative infection of thyroidectomy wound
• Absent parathyroid gland
• Hypoparathyroidism after external beam radiotherapy
• Hypoparathyroidism after iodine thyroid ablation
• Hypoparathyroidism following procedure
• Postablative hypoparathyroidism
• Post-surgical hypoparathyroidism
• Post-thyroidectomy hypoparathyroidism
• History of subtotal thyroidectomy
• History of thyroid lobectomy
• History of thyroidectomy
