Quick Answer: Among dyspepsia ICD-10 codes, dyspepsia that is not further specified goes to R10.13, Epigastric pain. The ICD-10-CM Tabular List lists “Dyspepsia” under R10.13. Use K30 only when the provider documents functional dyspepsia; K30 has an Excludes1 note for dyspepsia NOS.

FY2027 note: This guide reflects the FY2027 ICD-10-CM code set, effective October 1, 2026. We verified these codes in the ICD-10-CM Tabular List. However, always confirm against the code set in effect on the date of service.
In practice, dyspepsia is one of the GI diagnoses coders miss most often. Many coders reach for K30 any time they see the word, but the Tabular List draws a clear line between plain dyspepsia and functional dyspepsia. As a result, getting this right matters for clean claims and accurate data.
Dyspepsia ICD-10 Codes at a Glance
| Documentation | ICD-10-CM code | Description |
|---|---|---|
| Dyspepsia, NOS | R10.13 | Epigastric pain (includes dyspepsia) |
| Functional dyspepsia | K30 | Functional dyspepsia (includes indigestion) |
| Heartburn | R12 | Heartburn |
| Nervous or psychogenic dyspepsia | F45.8 | Other somatoform disorders |
Why Dyspepsia NOS Goes to R10.13
Look at category K30 in the Tabular List. It carries an Excludes1 note listing dyspepsia NOS (R10.13), heartburn (R12), and nervous or psychogenic dyspepsia (F45.8). An Excludes1 note means “not coded here.” Therefore, when the provider simply writes “dyspepsia,” K30 is not the right code.
Now look at R10.13, Epigastric pain. “Dyspepsia” appears as an inclusion term, and R10.13 has its own Excludes1 note for functional dyspepsia (K30). The two codes point at each other, which tells you they are mutually exclusive.
When to Use K30 Functional Dyspepsia
Assign K30 when the provider documents functional dyspepsia. Also, the Tabular List places “Indigestion” under K30. If the documentation is unclear, query the provider rather than choosing between R10.13 and K30 on your own.
Coding Tips
- Always start in the Alphabetic Index, then verify in the Tabular List. The notes at K30 and R10.13 are what settle this code choice.
- In addition, code the underlying cause when the provider documents it. If the provider confirms a definitive diagnosis such as GERD or gastritis, code that condition instead of the symptom.
- Finally, heartburn alone is R12, not dyspepsia.
