ICD-10 Code I26.99 – Other pulmonary embolism without acute cor pulmonale (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I26.99 – Other pulmonary embolism without acute cor pulmonale
What it is
I26.99 identifies a pulmonary embolism that does not include acute cor pulmonale and does not fit a more specific pulmonary embolism code. Use it when the record confirms a PE, but the documentation is nonspecific or categorized as other.
Clinical signs
Clinical features vary; refer to documentation. Common findings in pulmonary embolism include sudden shortness of breath, pleuritic chest pain, cough, or unexplained tachycardia, but the code itself depends on documented diagnosis rather than symptoms alone.
When to use this code
Use I26.99 when the provider documents pulmonary embolism without acute cor pulmonale and no more specific subtype is stated. It also applies when imaging or clinical notes confirm PE, but the source, chronicity, or vessel location is not further specified. Check documentation if another I26 code is supported.
Do not use for
Do not use this code for pulmonary embolism with acute cor pulmonale, which requires a different code. Also avoid it when the record supports a more specific embolism type or when PE is only suspected, not confirmed.
Coding tip
Code from the provider’s final diagnosis and choose the most specific pulmonary embolism code supported by the record.
