Q38.0Congenital malformations of lips, not elsewhere classified

Billable / specific codeICD-10-CMPOA exempt

Q38.0 is a billable, specific ICD-10-CM code for congenital malformations of lips, not elsewhere classified. 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.

  • cleft lip (Q36.-)
  • cleft lip with cleft palate (Q37.-)
  • macrocheilia (Q18.6)
  • microcheilia (Q18.7)

Inclusion terms

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

  • Congenital fistula of lip
  • Congenital malformation of lip NOS
  • Van der Woude's syndrome

Other codes that can never be billed with Q38.0

These codes carry an Excludes1 note pointing at Q38.0. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading Q38.0 alone.

Risk adjustment

Q38.0 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.

How Q38.0 is indexed

Coders do not find codes by browsing the tabular list — they look them up in the alphabetic index, under the word the physician wrote. These are the index entries that lead here, so you can see which chart wordings map to Q38.0.

  • Van der Woude's syndrome
  • Agenesislip
  • Anomaly, anomalouslip
  • Malformationlip
  • Deformitylip NECcongenital
  • Ectropionlipcongenital
  • Fistulalipcongenital
