ICD-10 codes for hypertension
Essential (primary) hypertension is coded I10 in both ICD-10 and ICD-10-CM. The complexity starts when hypertension involves the heart or kidneys — combination codes then take precedence over I10.
Notat skriver notatet — og foreslår disse koder
Den samme FactsContext™-motor, der extractor koder her, gør hele konsultationen til et struktureret klinisk notat, hvor hver kode er knyttet til den sætning, der understøtter den. Du gennemgår og underskriver hvert notat.

Hypertension ICD-10 codes
Start with the primary code, then move to a more specific related code when the documentation supports it.
| Kode | Beskrivelse | System |
|---|---|---|
I10 | Essential (primary) hypertension | ICD-10-CM |
I11.9 | Hypertensive heart disease without heart failure | ICD-10-CM |
I12.9 | Hypertensive chronic kidney disease, stage 1–4 or unspecified CKD Code also the CKD stage (N18.-) | ICD-10-CM |
I13.10 | Hypertensive heart and CKD without heart failure, stage 1–4 CKD | ICD-10-CM |
I15.9 | Secondary hypertension, unspecified Code also the underlying condition | ICD-10-CM |
R03.0 | Elevated blood-pressure reading, without diagnosis of hypertension | ICD-10-CM |
Sådan vælger du den rigtige kode
Use I10 only for essential hypertension without documented heart or kidney involvement. If hypertensive heart disease is documented, move to I11.-; with chronic kidney disease, I12.- plus the N18.- stage; with both, I13.-. A single elevated reading without a hypertension diagnosis is R03.0, not I10. Secondary hypertension (I15.-) requires coding the underlying cause.
Dokumentationseksempel
“Follow-up for essential hypertension. Home readings averaging 148/92 despite lifestyle changes. No chest pain, no dyspnea. Renal function normal (eGFR 84). Increased amlodipine to 10 mg daily; review in 6 weeks.”

FAQ
What is the ICD-10 code for hypertension?
The ICD-10 code for hypertension is I10 (Essential (primary) hypertension). Related codes include I11.9, I12.9, I13.10. Confirm the most specific code against the documented clinical detail before billing.
When do I use I10 vs I11 or I12?
I10 covers essential hypertension alone. Once the documentation links hypertension to heart disease (I11.-) or chronic kidney disease (I12.-, plus an N18.- stage code), those combination codes replace I10.
What code do I use for an elevated reading without a diagnosis?
R03.0 — elevated blood-pressure reading without a diagnosis of hypertension. I10 requires an established diagnosis.
Can AI suggest hypertension codes from my note?
Yes. Notat’s FactsContext™ engine extracts the clinical facts from your note or consultation and suggests ICD-10 codes with the supporting evidence excerpt, for you to review and confirm.
