Q45.3

Q45.3 — Other congenital malformations of pancreas and pancreatic duct

Billable / specific codeICD-10-CMPOA exempt

Q45.3 is a billable, specific ICD-10-CM code for other congenital malformations of pancreas and pancreatic duct. 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 diabetes mellitus (E10.-)
cystic fibrosis (E84.0-E84.9)
fibrocystic disease of pancreas (E84.-)
neonatal diabetes mellitus (P70.2)

Inclusion terms

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

Accessory pancreas
Congenital malformation of pancreas or pancreatic duct NOS

Excludes2 inherited from the categories above Q45.3

Also inherited, and the opposite of Excludes1: these conditions are not part of Q45.3, but a patient can have both, so you may code both.

Written on Q45 — Other congenital malformations of digestive system

congenital diaphragmatic hernia (Q79.0)
congenital hiatus hernia (Q40.1)

Risk adjustment

Q45.3 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

Q45.3 is named in 2 Medicare coverage policies — 2 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
