Final answer:
The correct ICD-10 codes for a patient admitted with anemia due to end-stage renal disease and receiving treatment for anemia would be N18.6, D63.1, which represents 'End-stage renal disease' and 'Anemia in chronic kidney disease', respectively.
Step-by-step explanation:
The question provided is regarding the correct coding for a patient who has been admitted with anemia due to end-stage renal disease (ESRD) and is being treated for anemia. In medical coding, particularly using the International Classification of Diseases, 10th Revision (ICD-10), codes are assigned to diagnoses and procedures documented in patient records. According to the ICD-10 coding system, N18.9 stands for 'Chronic kidney disease, unspecified', which may not be the most accurate for end-stage renal disease, as N18.6 ('End-stage renal disease') specifically indicates the most severe form of chronic kidney disease. D63.1 is the code for 'Anemia in chronic kidney disease' while D63.0 is for 'Anemia in neoplastic disease'. Since the question states the anemia is due to end-stage renal disease, the correct coding would be N18.6 for end-stage renal disease and D63.1 for anemia associated with chronic kidney disease, which makes the correct answer (d) N18.6, D63.1.
