I50Heart failure

Non-billable headerICD-10-CM

I50 is a non-billable header ICD-10-CM code for heart failure. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

  • cardiac arrest (I46.-)
  • neonatal cardiac failure (P29.0)

Code first

The underlying condition must be sequenced before this code.

  • heart failure complicating abortion or ectopic or molar pregnancy (O00-O07, O08.8)
  • heart failure due to hypertension (I11.0)
  • heart failure due to hypertension with chronic kidney disease (I13.-)
  • heart failure following surgery (I97.13-)
  • obstetric surgery and procedures (O75.4)
  • rheumatic heart failure (I09.81)

Other codes that can never be billed with I50

These codes carry an Excludes1 note pointing at I50. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading I50 alone.

  • I50.2Systolic (congestive) heart failure
  • I50.3Diastolic (congestive) heart failure
  • I50.814Right heart failure due to left heart failure
  • J81Pulmonary edema

Risk adjustment

I50 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.

Code to one of these instead I50

6 child codes. Green means billable.
