Q89.2

Q89.2 — Congenital malformations of other endocrine glands

Billable / specific codeICD-10-CMPOA exempt

Q89.2 is a billable, specific ICD-10-CM code for congenital malformations of other endocrine glands. It is valid for submission on a claim.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

congenital goiter (E03.0)
congenital hypothyroidism (E03.1)

Inclusion terms

Alternative wordings a physician may use in the chart for this same code.

Congenital malformation of parathyroid or thyroid gland
Persistent thyroglossal duct
Thyroglossal cyst

Other codes that can never be billed with Q89.2

These codes carry an Excludes1 note pointing at Q89.2. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q89.2 alone.

Q18Other congenital malformations of face and neck

Risk adjustment

Q89.2 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Medicare coverage

Q89.2 is named in 1 Medicare coverage policy — 1 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
