R10.85Abdominal pain of multiple sites

Billable / specific codeICD-10-CM

R10.85 is a billable, specific ICD-10-CM code for abdominal pain of multiple sites. 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.

  • abdominal rigidity NOS (R19.3)
  • generalized abdominal pain associated with acute abdomen (R10.0)
  • generalized abdominal pain NOS (R10.84)
  • localized abdominal pain (R10.1-R10.4-)

Risk adjustment

R10.85 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.
