Final answer:
The correct ICD-10 code for a patient with a family history of colonic polyps is Z83.71, which should be used in the medical documentation for proper coding and subsequent healthcare management.
Step-by-step explanation:
The correct code for a patient with a history of colonic polyps is Z83.71. This code is used when there is a family history of digestive disorders, which includes colonic polyps.
Colorectal cancer can be indicated by various symptoms, and the primary method of prevention is the detection and removal of colonic polyps through a colonoscopy. Since the patient's parents both had colonic polyps, the family history is relevant to the patient's risk and is coded accordingly. This helps in guiding clinician decision-making regarding surveillance and management strategies.
