Q18: Other congenital malformations of face and neck

Non-billable headerICD-10-CM

Q18 is a non-billable header ICD-10-CM code for other congenital malformations of face and neck. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1: never code together

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

cleft lip and cleft palate (Q35-Q37)
conditions classified to Q67.0-Q67.4
congenital malformations of skull and face bones (Q75.-)
cyclopia (Q87.0)
dentofacial anomalies [including malocclusion] (M26.-)
malformation syndromes affecting facial appearance (Q87.0)
persistent thyroglossal duct (Q89.2)

Other codes that can never be billed with Q18

Their own Excludes1 notes name this code, so the conflict is not listed above.

H70.8Other mastoiditis and related conditions
K13.0Diseases of lips
Q17Other congenital malformations of ear
Q17.4Misplaced ear
Q38Other congenital malformations of tongue, mouth and pharynx
Q38.0Congenital malformations of lips, not elsewhere classified
