QUESTION: Recently, reviewers have denied diagnostic code 584.9 (acute renal failure [ARF]) based on lab values. The diagnosis is well documented and treated by the attending physician, but reviewers are stating the lab values do not support the diagnosis of ARF. The lab values (creatinine/blood urea nitrogen) went from normal to abnormal, and we found no definitive standards for lab parameters to meet the definition of ARF. Following coding guidelines for reporting secondary diagnoses, the ARF was clinically evaluated, the patient received therapeutic and diagnostic procedures, and there was an extended length of stay/increased nursing care. As coders, we feel it is inappropriate to question the physician’s clinical judgment, and reporting the ARF as a secondary diagnosis is correct. Based on the documentation in the record, is it appropriate to code the ARF?
The 2016 IPPS final rule continues CMS’ plan to shift Medicare payments from volume to quality. Shannon Newell, RHIA, CCS, and James S. Kennedy, MD, CCS, CDIP, analyze the rule and the impact it could have on providers.
ICD-10-PCS root operations Drainage, Extirpation, and Fragmentation involve removing material from the body, but in different ways. A nita Rapier, RHIT, CCS, Kristi Stanton, RHIT, CCS, CPC, and James Fee, MD, CCS, CCDS, offer tips for distinguishing between the root operations.
Complete capture of procedure codes in ICD-9-CM helps to ensure accurate translation to ICD-10-PCS. Donna M. Smith and Patricia L. Belluomini, RHIA, reveal coding errors—including omission of procedure codes—that make the translation process more challenging.
Many coders and CDI specialists memorized previous Official Guidelines for Coding and Reporting , Coding Clinic for ICD-9-CM and do not have to give them a lot of forethought before applying correctly to their day-to-day reviews. Although many of the Official Guidelines for Coding and Reporting remain the same in ICD-10, none of Coding Clinic's previous advice can be applied to the new code set. Without years of new Coding Clinic advice under their belts, it may take some time before the staff exhibits the same ease when applying ICD-10-CM/PCS codes to the documentation provided.
Inpatient coding professionals are used to DRG systems where all of the diagnoses and procedures map to a single DRG. So they may not look for additional procedures and services to report outside of that DRG.
Perhaps you're familiar with the following scenario: A hospital submits a short-stay inpatient (Part A) claim. An auditor, such as a RAC or MAC, reviews the claim and deems the admission to be not reasonable and necessary due to the hospital billing the wrong setting. The auditor issues a denial for the full amount of the claim. Although the hospital may rebill for certain Part B ancillary services before the timely filing limit, it may not bill for any of the other outpatient services denied as part of the inpatient claim.
