Medical Billing & Coding
posted by Dee .
A physician performed an aspiration via thoracentesis on a patient in observation status in the hosptial. The patient has advanced lung cancer with malignant pleural effusion. Later the same day, due to continued accumulation of fluid, the patient was returned to the procedure room and the same physician performed a repeat thoracentesis.
Do not code observation status.
two diagnosis codes: two CPT codes are needed``
