K30 — Functional dyspepsia
K30 is a billable, specific ICD-10-CM code for functional dyspepsia. 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.
Inclusion terms
Alternative wordings a physician may use in the chart for this same code.
- Indigestion
Other codes that can never be billed with K30
These codes carry an Excludes1 note pointing at K30. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading K30 alone.
Risk adjustment
K30 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
K30 is named in 3 Medicare coverage policies — 3 listing it as supporting medical necessity. Which of them applies to you depends on your Medicare contractor, and coverage genuinely differs by state.
