Pulmonary Embolism ICD-10-CM codes

Category I26 splits on whether acute cor pulmonale (acute right heart strain) is documented: I26.0- with and I26.9- without. An acute PE with no further detail is I26.99. A saddle embolus is I26.92 or I26.02, and subsegmental thrombotic emboli are I26.93 (single) or I26.94 (multiple). Fat embolism (I26.96, I26.04) and cement embolism (I26.95, I26.03) have their own codes.

Septic pulmonary embolism (I26.90 or I26.01) requires the underlying infection to be coded first, for example endocarditis or a septic thrombophlebitis. When a deep vein thrombosis is also documented, code the DVT from I82 in addition to the PE.

A chronic pulmonary embolism, meaning a persistent clot still under treatment after the acute phase, is I27.82 rather than I26. Chronic thromboembolic pulmonary hypertension is I27.24. A resolved PE with no current treatment is reported with Z86.711, and Z79.01 is added whenever the patient remains on long-term anticoagulants, whether the PE is acute, chronic, or historical.

PE complicating pregnancy, childbirth, or the puerperium is classified to O88.-, and PE following a procedure is reported with the appropriate T80 to T82 complication code. These are Excludes2 conditions at the I26 level, so I26 is only added when the provider documents a separate acute PE.
