Post Obstructive Pneumonia

The referral states the patient has lung cancer and then it also lists post-obstructive pneumonia several times restricted to one area due tumor growth. She isn't on any kind of antibiotics and has COPD also. My initial thought was to code the cancer, then J17...? Pneumonia in diseases classified elsewhere and to not connect to the COPD. Thoughts?


  • I wouldn't connect the COPD, either, being that the pneumonia had been stated as related to the cancer. It's only automatically assumed connected to COPD when the doctor(s) haven't mentioned it to be connected to something else.
