K22.5 — Diverticulum of esophagus, acquired
K22.5 is a billable, specific ICD-10-CM code for diverticulum of esophagus, acquired. 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.
- diverticulum of esophagus (congenital) (Q39.6)
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Esophageal pouch, acquired
Risk adjustment
K22.5 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
K22.5 is named in 5 Medicare coverage policies — 5 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
