Q: A patient presents with a sore throat, and the physician states “Sore throat; differential diagnoses include streptococcal sore throat, tonsillitis, postnasal drip.” If the physician doesn’t rule out any of the differential diagnoses, should the coder query for clarification or simply choose one of the differential diagnoses?
According to the ICD-9-CM Official Guidelines for Coding and Reporting, it’s unusual for two or more diagnoses to meet the definition of principal diagnosis. Coders know the opposite is true. William E. Haik, MD, FCCP, CDIP, Donna Didier, MEd, RHIA, CCS, and Cheryl Ericson, MS, RN, CCDS, CDIP, offer tips for determining whether multiple conditions meet the criteria for principal diagnosis.
As more patients are being impacted by noncoverage of self-administered drugs, coders and billers need to know when and how to report drugs and drug administration services. Kimberly Anderwood Hoy, JD, CPC, and Valerie Rinkle, MPA, discuss the differences in how drugs are paid under Medicare Part A and Part B.
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.
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.
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?
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?
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.
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.
