Q: A patient has been diagnosed with peritonsillar cellulitis and oropharyngeal cellulitis. The physician documents that he performed a “needle aspiration of the left peritonsillar abscess.” In the body of the operative report, the physician states, “An 18-gauge needle was inserted and 1 cc of pus was aspirated. This was sent for aerobic, anaerobic, C&S [culture & sensitivity], and gram stain. I then put the 18-gauge needle in again and multiple passes were obtained without any aspirate.” Because ICD-9-CM does not include a code for “aspiration of peritonsillar abscess” some coders wanted to use ICD-9-CM procedure code 28.0 (incision and drainage of tonsil and peritonsillar structures) while others want to report code 28.99 (other operations on tonsils and adenoids). Which code is correct?
Physicians often use the acronyms IBS (which should indicate irritable bowel syndrome) and IBD (which should indicate inflammatory bowel disease) interchangeably even though they represent completely different conditions with different treatment and prognoses. Robert S. Gold, MD, and Drew K. Siegel, MD, CPC, offer tips on how to decipher documentation related to these two conditions.
QUESTION: I'd like to address our coders' questions on how to code poisoning due to bath salts. Internet research has led me to many different options: codes 977.8 (other specified drug/medicinal), 970.89 (other CNS stimulant), 969.70 (psychostimulant, unspecified), among others. What would you suggest? There don't seem to be any guidelines out there and the coding for this seems to be all over the place.
QUESTION: A patient is admitted with pneumonia and atrial fibrillation and both are present on admission. The patient receives antibiotics for the pneumonia and a pacemaker during the stay, but undergoes no other procedures. Does the procedure automatically make ICD-9-CM code 427.31 for the atrial fibrillation the principal diagnosis?
New clinical guidelines for malnutrition could help alleviate compliance challenges associated with coding the condition, which has never had universally accepted clinical criteria. Jane White, James S. Kennedy, MD, CCS, CDIP, and Alice Zentner, RHIA, describe the new guidelines and what coders need to know about malnutrition coding.
The digestion process is complex and there’s a lot that can go wrong. Thankfully, Robert S. Gold, MD, unravels the topic of mechanical and paralytic ileuses in this week’s article.
Choosing a principal diagnosis can be tricky for coders. Luckily, Gloryanne Bryant, BS, RHIA, RHIT, CCS, CDIP, CCDS, and Robert S. Gold, MD, help unravel the complexities of principal diagnosis selection.
Why do coders need to know about Value Based Purchasing, the Readmissions Reduction Program, and Hierarchical Condition Categories codes? Glenn Krauss, RHIA, CCS, CCS-P, CPUR, C-CDI, CCDS, explains why it all comes back to coding accuracy and complete documentation.
QUESTION: A patient was exposed to shingles, for which a coder reported ICD-9-CM code V01.79 (exposure to other viral diseases, including HIV). This poses a problem for billing as code V01.79 is a confidential diagnosis, requiring special release of information from the patient and would remain on the insurance record. As an RN and certified coder, I believed code V01.71 (exposure to varicella) is the correct code because the varicella virus causes both chicken pox and shingles. However, I am being overridden by the chief business office. Which code is correct?
Medical necessity denials traditionally focus on high-dollar MS-DRGs, such as those for hip and knee replacements; other MS-DRGs may also soon become targets, such as inpatient wound care, according to Nelly Leon-Chisen, RHIA, and Glenn Krauss, BBA, RHIA, CCS, CCS-P, CPUR, PCS, FCS, C-CDIS, CCDS. Krauss and Leon-Chisen discuss coverage determinations, excisional vs. nonexcisional debridement, debridement of multiple layers, and more.
QUESTION: Do you predict coder productivity will decline as a result of ICD-10? If so, what do you think the declines will be six months after implementation?
Depending on the demographics of the region a hospital serves, its coders could determine code assignment for hundreds of deliveries and pregnancy-related services annually. Lori-Lynne Webb, CPC, CCS-P, CCP, CHDA, COBGC, and Susan Proctor, RHIT, CCS, CPC, review the relevant coding guidelines for coders who handle coding for these patient encounters.
QUESTION: Our pulmonologists are not comfortable documenting acute respiratory failure unless the patient is on a ventilator. Also, they rarely document chronic respiratory failure, even in chronic obstructive pulmonary disease (COPD) patients on continuous home oxygen. I’m trying to develop standard query forms for acute and chronic respiratory failure and am running into these obstacles. How do you recommend handling this problem?
Many physicians say that systemic inflammatory response syndrome (SIRS) criteria are insufficient and confusing at best, and don't indicate whether a patient is truly sick. Some patients may meet necessary criteria for SIRS and truly have sepsis or another severe diagnosis. Others, however, may meet two of four criteria but not actually have SIRS. Where does all of this information leave coders? Often between a rock and hard place. Jennifer E. Avery, CCS, CPC-H, CPC, CPC-I, and Robert S. Gold, MD, offer seven tips for coders who need to negotiate tricky sepsis coding.
QUESTION: A physician documents in an operative report debridement of a necrotic muscle (not due to an open wound). Must the physician also document how the muscle is removed to report ICD-9-CM procedure code 83.45 (other myectomy)? Is this considered excisional or nonexcisional debridement? What documentation is required to code the removal of a necrotic portion of a muscle?
Although MS-DRGs have stolen the spotlight since CMS implemented them in 2007, hospitals are increasingly using All Patient Refined DRGs (APR-DRG) to compile the most accurate assessment of patient severity of illness (SOI) and risk of mortality (ROM). Cheryl M. Manchenton, RN, BSN, and Tamara A. Hicks, RN, BSN, MHA, CCS, CCDS, ACM, describe why APR-DRGs are the most widely-used SOI and ROM-adjusted DRGs and how organizations can use them to their advantage.
QUESTION: How will we be able to code for procedures such as Billroth procedures, Roux-en-Y anastomoses, and Whipple’s procedure when eponyms won’t be used in ICD-10-PCS?
Unfortunately, ICD-10-PCS is not very comparable to the current ICD-9-CM volume 3 codes inpatient coders currently use. But coders shouldn’t despair, according to Sandy Nicholson, MA, RHIA, Jennifer Avery, CCS, CPC-H, CPC, CPC-I and Robert S. Gold, MD —ICD-10-PC coding may even be fun once coders get the hang of it.
QUESTION: For a healing traumatic finger amputation with concern but no diagnosis of infection at the amputation site (the physician prescribed Bactrim), is it correct to assign code V54.89 (other orthopedic aftercare) and ICD-9-CM code 886.x (traumatic amputation of finger)?
QUESTION: We are having a discussion about how to code when the studies section of the history and physical (H&P) indicates that the chest x-ray showed atelectasis or that an electrocardiogram showed right bundle branch block with anterior fascicular block. Some of us believe that it’s okay to code the diagnosis (i.e., atelectasis) if the provider states that the testing “showed” the diagnosis, whereas others believe we cannot code the diagnosis as it is a lab/testing result, and the provider could just be reading the results onto his or her H&P dictation. I realize you cannot go to the testing result itself and code from it directly. However, I argue that it would be okay to code for it because the provider is using this information to make decisions about care, testing, and procedures, and he or she indicates the testing results in the H&P body. What are your thoughts?
