Q: Should “diabetes with gastroparesis” be coded as 536.3, diabetes with a complication code? I understood that the term ‘"with’" can link two diagnoses, but that it does not represent a cause-and-effect relationship. Can you please clarify this, and why a cause-and-effect relationship can be assumed in the term “diabetes with gastroparesis”?
Coders and clinical documentation improvement specialists need to pay attention to what conditions are considered CCs and MCCs, as well as sequencing rules which could affect MS-DRGs. Laurie L. Prescott, MSN, RN, CCDS, CDIP, AHIMA-approved ICD-10-CM/PCS trainer, and William E. Haik, MD, FCCP, CDIP, AHIMA-approved ICD-10-CM/PCS trainer, discuss some common CCs and MCCs.
Q: A patient came to the ED with shortness of breath (SOB). The admitting diagnosis was possible acute coronary syndrome (ACS) due to SOB and elevated troponin levels. The ACS was ruled out. Elevated troponin levels were assumed to be due to chronic renal failure (CRF), and no reason was given for SOB. Before discharge, the patient was noted with an elevated temperature and found to have a urinary tract infection (UTI). All treatment was directed at the UTI, and the doctor noted the discharge diagnosis as the UTI. What would be the principal diagnosis in this case?
Heart failure is the intrinsic inability of the heart to supply target organs with sufficient nutrient flow to function normally. Robert S. Gold, MD, and Gloryanne Bryant, RHIA, RHIT, CCS, CDIP, CCDS, review the clinical and coding guidelines for heart failure.
In ICD-10-CM, coders will use a seventh character, not an aftercare code, to identify follow-up treatment for an injury. Glenn Krauss, BBA, RHIA, CCS, CCS-P, CPUR, FCS, PCS, CCDS, C-CDI, C-DAM, Kristi Pollard, RHIT, CCS, CPC, CIRCC, and Anita Rapier, RHIT, CCS, explain how aftercare coding will change in ICD-10-CM.
The physician documented “encephalopathy” in the progress note of a patient who was admitted with a cerebrovascular accident (CVA) and/or possible seizures. James S. Kennedy , MD, CCS, CDIP, discusses what to consider when determining whether to code the encephalopathy.
ICD-9-CM and ICD-10-CM differentiate between acute and chronic meniscus tears. Kristi Pollard, RHIT, CCS, CPC, CIRCC , and Gretchen Young-Charles, RHIA, review how to code these injuries in both systems.
Q: How should the diagnosis of urinary tract infection (UTI) and encephalopathy be sequenced, specifically which diagnosis should be the principal? If physician documentation indicates that the patient came in with confusion, can encephalopathy be assigned as the principal diagnosis if it is due to the UTI and no other contributing issues are present?
Q: Can CDI programs use the information on ambulance forms or trip tickets to abstract from if the information is pulled into or reiterated in the ED or history and physical (H&P) documentation? Our staff doesn’t want to miss criteria that would diminish our ability to substantiate the true severity of illness of some patients, but I have been informed that coders are not allowed to code from ambulance papers or information.
Q: A patient comes in with a malunion of a fracture. A different physician treated the patient initially for the fracture, but the patient came to see our physician for surgery to repair the malunion. Which seventh character should we use: A for initial encounter or P for subsequent encounter for fracture with malunion?
In order to identify patients with a CC or MCC, coders need to know when to report additional diagnoses. William E. Haik, MD, FCCP, CDIP, and Jennifer E. Avery, CCS, CPC-H, CPC, CPC-I, discuss when to report a secondary diagnosis.
Q: When atelectasis is noted on an ancillary test such as a CT scan of the abdomen or chest x-ray, can nursing documentation of turning, coughing, and deep breathing be considered an intervention that qualifies as one of the criteria to meet a secondary diagnosis?
In some cases, coding professionals can—and should—report ancillary services provided to inpatients. Denise Williams, RN, CPC-H, and Valerie A. Rinkle, MPA, explain when and how to bill for ancillary bedside services.
