Final answer:
The ICD-10-CM code for the patient with abnormal prothrombin time and undetermined cause would depend on the specific diagnosis given by the healthcare provider.
Step-by-step explanation:
The ICD-10-CM code for the patient with abnormal prothrombin time and undetermined cause would depend on the specific diagnosis given by the healthcare provider. The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a system used to classify and code diagnoses in healthcare. It consists of alphanumeric codes that represent different medical conditions.
For example, if the patient's abnormal prothrombin time is due to liver disease, the ICD-10-CM code could be K76.6 (Liver Disease, Unspecified). If the cause is genetic, it could be D68.3 (Hereditary Thrombophilia). It is important to consult the healthcare provider or the medical documentation for the specific diagnosis to assign the correct ICD-10-CM code.
