CMS not only redefines inpatient status in the 2014 IPPS proposed rule, but it also discusses the ‘why’ and ‘how’ physicians should document the defining characteristic of all admissions: medical necessity. Glenn Krauss, BBA, RHIA, CCS, CCS-P, CPUR, C-CDI, CCDS, and Cheryl Ericson, MS, RN, CCDS, CDIP, explain how the proposals could impact inpatient admissions.
Q: We’re having a lot of discussions with physicians right now and need to get some clarity on acute cor pulmonale versus chronic. Do you have any insight on that differentiation between the two with right-sided heart failure, chronic obstructive pulmonary disease (COPD), shortness of breath, and edema?
Physicians use a lot of shortcuts and abbreviations. Some of them may even make it to the official abbreviation list at a hospital. Some don't. Even if they do, some physicians will use the wrong term.
The goals of coding should always be ensuring data accuracy and capturing a patient's true clinical picture. Knowing the intent of an ICD-9-CM code is crucial. However, coding guidelines and official coding guidance sometimes conflict with these goals, putting coders between a rock and a hard place. Robert S. Gold, MD, examines cardiomyopathy, a disease that affects the heart muscle, as an example of a diagnosis that is frequently misreported due to inaccurate guidance.
Q: A patient is admitted with a high white blood count, tachycardia, tachypnea, and chills. The blood culture shows positive for methicillin-resistant Staphylococcus aureus (MRSA). The attending physician documents MRSA sepsis in the progress notes. Antibiotics are changed based on the blood culture and the patient is treated with appropriate antibiotics. Due to poor vascular access, a central venous catheter (CVC) is inserted and antibiotics are infused through this access. The patient responded slowly to treatment and CVC access becomes red and inflamed. The catheter is removed and cultured. The physician documents this to be an infection due to MRSA. What’s the diagnosis code for this?
For coders, the summer months can be some of the busiest, particularly for those working in areas that attract tourists. Linda Schwab Messmer, RHIT, CCS, and Lori-Lynne A. Webb, CPC, COBGC, CCS-P, CCP, CHDA, review ICD-9-CM codes for common summer injuries and ailments.
Q: Our physicians document a diagnosis of pneumonia but do not normally make a specific connection with the patient's ventilator status, even when this is obvious from the record. For example, the patient's been on the ventilator support immediately prior to the diagnosis. Can I report this as ventilator-associated pneumonia in ICD-10-CM without the documentation specifically connecting the conditions?
Q: One of our orthopedic surgeons started to perform spinal fusions percutaneously. CPT ® provides instruction on how to code this procedure; however, these are inpatient surgeries, so we need an ICD-9-CM code. We’re leaning toward code 81.00 (spinal fusion unspecified). Do you think this is the correct code?
