ICD-10 Code I26.94 – Multiple subsegmental thrombotic pulmonary emboli without acute cor pulmonale (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I26.94 – Multiple subsegmental thrombotic pulmonary emboli without acute cor pulmonale
What it is
This code identifies more than one thrombotic pulmonary embolus in the subsegmental branches of the pulmonary arteries, without acute cor pulmonale. It reflects a clot-related blockage in the lungs, with no documented acute strain on the right side of the heart.
Clinical signs
Clinical features may include sudden shortness of breath, pleuritic chest pain, cough, or unexplained tachycardia. Imaging or other diagnostic evidence should support multiple subsegmental pulmonary emboli; clinical features vary, so refer to documentation.
When to use this code
Use I26.94 when the record clearly documents multiple subsegmental thrombotic pulmonary emboli and does not state acute cor pulmonale. It is appropriate for confirmed PE in the subsegmental arteries, whether found on imaging or described in the final diagnosis. If the note only says “pulmonary embolism” or the clot location is unclear, check documentation.
Do not use for
Do not use this code for a single subsegmental embolus, nonthrombotic pulmonary embolism, or pulmonary embolism with acute cor pulmonale. If the documentation does not specify multiple subsegmental thrombotic emboli, check documentation.
Coding tip
Confirm both the number of emboli and the absence of acute cor pulmonale before assigning I26.94.
