ICD-10-PCS differs significantly from ICD-9-CM procedure coding, but fortunately, the Cooperating Parties are providing plenty of guidelines. Laura Legg, RHIT, CCS, discusses some of the key ICD-10-PCS guidelines and why coders should learn them.
The ICD-9-CM guidelines state that it's unusual for two or more diagnoses to meet the definition of principal diagnosis. However, coders know this isn't exactly true, as the scenario tends to occur frequently.
In times of increased auditor scrutiny, it's important for coders to remind themselves of their strengths. Assigning the POA indicator is one of them, according to an OIG report released in November 2012.
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?
Coders should avoid reporting signs and symptoms as the principal diagnosis when possible. However, that’s not always possible. William E. Haik, MD, FCCP, CDIP, reviews the ICD-9-CM principal diagnosis selection guidelines and when coders should report signs and symptoms as the principal diagnosis.
Physicians, especially ED physicians, need to start paying attention to how their documentation affects the facility. Glenn Krauss, BBA, RHIA, CCS, CCS-P, CPUR, C-CDI, CCDS, and Bernadette Larson, CPMA, discuss how documentation in the ED affects medical necessity and inpatient coding.
Q: I’ve heard that queries differ between critical access and short-term acute care hospital settings. Is this true, and if so, where can I find more information?
MLN Matters ® article SE1236, which discusses documenting medical necessity for major joint replacements, may be aimed at physicians, but Glenn Krauss, RHIA, CCS, CCS-P, CPUR, PCS, FCS, C-CDIS, and Lynn Marlow, BS, RHIT, CCS, explain how it also applies to hospitals and coders.
Q: A patient has unintentionally failed to take a prescribed dosage of insulin due to his Alzheimer’s dementia (age-related debility), and is admitted for initial care with inadequately controlled Type 1 diabetes mellitus. Which ICD-10-CM code(s) should we assign?
Q: As a traveling consultant, I review many types of inpatient hospital records. As hospitals have implemented electronic health records (EHR), I’ve seen documentation worsen. The ability to cut and paste information in the record has compromised coding accuracy. It has also increased the volume of queries, which frustrates physicians. For example, a physician performs a history and physical (H&P) in his or her office one week prior to admitting a patient to the hospital. The first progress note in the EHR—as well as each subsequent progress note—includes the exact same documentation. This documentation, which continues for four days while the patient is in the hospital, is clearly based on the original H&P. Obviously, the documentation has been copied and pasted from one note to another. Even the patient’s vital signs remain exactly the same as they were in the physician’s office. Coders have no way of knowing whether physicians who treat the patient in the hospital agree with any test findings because residents simply cut and paste the results in each subsequent progress note. Residents claim that they do this solely for the attending physician’s convenience. Clinical documentation improvement (CDI) specialists don’t address the problem because they are more focused on determining the accuracy of the MS-DRG. Is there a solution that will keep physicians, coders, and CDI specialists all on the same page?
Robert S. Gold, MD, gives coding guidance on primary cardiomyopathy, SIRS, sepsis, acute respiratory distress syndrome, and conditions during the perinatal period.
Q: Should we query for the specific pulmonary exacerbation of cystic fibrosis (CF)? Coding Clinic states that the exacerbation of CF should be listed first.
Every few years, the AHA publishes guidance in Coding Clinic that can significantly affect inpatient coders, such as guidance published in the Second Quarter 2012 on neoplasm coding. Randy Wagner, BSN, RN, CCS, and Paul Dickson, MD, CCS, CPC, review the new guidance and how to use the TNM cancer staging system.
Coders can go a bit overboard when reporting CCs and MCCs. Cheryl Ericson, MS, RN, CCDS, CDIP, and Deborah K. Hale, CCS, CCDS, reveal the dangers of over-reporting CCs and MCCs and how to report them appropriately.
Every few years, the AHA publishes guidance in Coding Clinic that can significantly affect inpatient coders. Coding Clinic , Second Quarter 2012, includes such guidance.
Q: I have a question about coding transplant complications. My understanding is if the complication affects the transplanted organ, then coders should assign a code for the transplant complication itself. Is this correct? Consider the following physician documentation: Final A/P: Acute renal failure in patient with history of renal transplant. Should coders report 996.81 (complications of transplanted kidney) and 584.9 (acute kidney failure, unspecified)? Also consider this documentation: CHF in heart transplant patient . Should coders report 996.83 (complications of transplanted heart) and 428.0 (CHF, unspecified)?
Provider documentation of inpatient wound care services may be confusing at best and completely lacking at worst. Coders end up trying to decipher exactly what procedure the provider performed. Gloryanne Bryant, BS, RHIA, RHIT, CCS, CDIP, CCDS, and Robert S. Gold, MD, offer tips to assist coders in choosing the correct code for inpatient wound care.
Inpatient-only procedures are those that CMS has determined providers must perform on an inpatient basis. Kimberly Anderwood Hoy, JD, CPC, and Beverly Cunningham, MS, RN, unravel the complexities of coding for these procedures.
As you may know, ICD-9-CM V codes have been expanded to include higher body mass indexes (BMI). More specifically, code category V85.4x denotes a BMI of 40 or more in an adult. How can you calculate BMI?
Inpatient-only procedures are those that CMS has determined providers must perform on an inpatient basis because they are invasive and require at least 24 hours of postoperative recovery time or monitoring.
Coders play a crucial role in ensuring compliance, and the FY 2013 IPPS final rule , released August 1, gives them many reasons to showcase their skills. William E. Haik, MD, FCCP, CDIP, and Glenn Krauss, BBA, RHIA, CCS, CCS-P, CPUR, C-CDI, CCDS, detail the changes and how coders can take charge of them.
Patients aren’t the only ones paying attention to quality scores these days. Payers are, too. Cheryl Manchenton, RN, BSN, and Audrey G. Howard, RHIA, explain why coders and clinical documentation improvement specialists must understand which conditions affect provider profiles.
Q: I need further clarification regarding documentation of toxic metabolic encephalopathy. I’m trying to code two different cases in which a physician documents acute mental status change secondary to an infectious process . In each case, the patient’s metabolic panels don’t appear to be abnormal; however, one of the patients is septic. The physician thinks that documenting and coding sepsis separately from encephalopathy would result in unbundling. However, I disagree because coding the sepsis separately demonstrates severity. What is the correct logic to use in each of these cases?
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.
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?

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.
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.
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?
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.
ICD-10-CM coronary artery disease and myocardial infarction codes will undoubtedly differ from their ICD-9-CM counterparts in some ways, but some aspects will remain the same.
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.
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?
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.
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.
