J94 — Other pleural conditions

Non-billable headerICD-10-CM

J94 is a non-billable header ICD-10-CM code for other pleural conditions. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

pleurisy NOS (R09.1)
traumatic hemopneumothorax (S27.2)
traumatic hemothorax (S27.1)
tuberculous pleural conditions (current disease) (A15.-)

Other codes that can never be billed with J94

These codes carry an Excludes1 note pointing at J94. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading J94 alone.

R60Edema, not elsewhere classified
J90Pleural effusion, not elsewhere classified

Risk adjustment

J94 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 J94

5 child codes. Green means billable.
