A 12-year-old male developed umbilical discomfort Monday and didn't eat much dinner. On Tuesday, he started vomiting at school and the pain shifted to his right lower quadrant. His parents brought him to the ED, where his vital signs showed:
Q: When I started as a coder, I learned that the complication code, such as from ICD-9-CM series 998 or 999, takes precedence as the reason of admission when present with another contributing condition. Is this correct, and is there any written guidance from AHA Coding Clinic for ICD-9-CM/ICD-10-CM/PCS that discusses this?
Physicians often use the terms acute renal failure (ARF) and acute kidney injury (AKI) interchangeably to describe an abrupt decrease in kidney function that is reversible within three months of loss of function.
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.
Q: If the physician documents “concerning for,” “considering,” “cannot be ruled out,” or “cannot be excluded” for a diagnosis, is that considered an uncertain diagnosis? Can those terms be coded if the patient is being worked up? Are the terms “concerning for” and “considering” equal to the uncertain diagnosis terms “yet to be ruled out”?
Each new CMS fiscal year, MS-DRG weight and classification changes in the CMS IPPS final rule are closely scrutinized by coders and CDI specialists to identify any potential impact on documentation capture and code assignment processes.
Q: A few days into the patient’s stay, an order for a Foley catheter was placed for incontinence and around the same time the physician documented a urinary tract infection (UTI). Would it be appropriate to query the physician regarding the relationship of the UTI to the Foley? Our infection control department caught this but we did not. I am concerned about this for two reasons; first, I worry about writing a leading query and second, whether the UTI could be considered a hospital-acquired condition (HAC) if additional documentation isn’t provided.
