ICD Code I27.0

ICD code I27.0 is primary pulmonary hypertension, a condition where high blood pressure occurs in the arteries of the lungs without a known secondary cause.

1. Persistent elevation of pulmonary arterial pressure confirmed by right heart catheterization

2. Mean pulmonary artery pressure ≥25 mmHg at rest

3. Pulmonary capillary wedge pressure ≤15 mmHg

4. Exclusion of secondary causes of pulmonary hypertension (e.g., left heart disease, chronic lung disease, thromboembolic disease)

5. Symptoms such as progressive dyspnea on exertion, fatigue, chest pain, syncope, or signs of right heart failure

6. Evidence of right ventricular hypertrophy or dysfunction on imaging or electrocardiogram

7. Absence of significant parenchymal lung disease on imaging

Relevant CPT codes that may be used to treat ICD code I27.0 include:

- 93451: Right heart catheterization

- 93452: Left heart catheterization

- 93453: Combined right and left heart catheterization

- 92960: Cardioversion, elective, external

- 96372: Therapeutic, prophylactic, or diagnostic injection (specify substance or drug); subcutaneous or intramuscular

- 96365: Intravenous infusion, for therapy, prophylaxis, or diagnosis; initial, up to 1 hour

- 99221-99223: Initial hospital care, per day, for the evaluation and management of a patient

- 99231-99233: Subsequent hospital care, per day, for the evaluation and management of a patient

- 99291: Critical care, evaluation and management of the critically ill or critically injured patient; first 30-74 minutes

CPT code selection should be based on the specific services rendered and clinical scenario.
