Final answer:
The correct ICD-10-CM codes for malignant hypertension with stage 4 chronic kidney disease would likely involve a combination of codes, including I10 for the hypertension, followed by the specific code for stage 4 chronic kidney disease, which is N18.4. It is always essential to verify coding guidelines as they can change over time.
Step-by-step explanation:
The correct ICD-10-CM code for malignant hypertension with stage 4 chronic kidney disease would require using a combination of codes to fully capture the health conditions described. Typically, in ICD-10-CM, the coding protocol requires first coding the underlying condition followed by the manifestation. In this case, the primary diagnosis of malignant hypertension is coded as I10 for primary hypertension. Since malignant hypertension is a severe form of hypertension which can lead to organ damage, it should be noted in the medical records accurately.
Next, the code for the chronic kidney disease should be added. The ICD-10-CM code for stage 4 chronic kidney disease is N18.4. Since hypertension can both cause and be complicated by chronic kidney disease, it's important to report both codes on the medical claim to provide a complete picture of the patient's health condition.
Keep in mind that coding guidelines and codes can change, and it is always recommended to verify the current ICD-10-CM codes and coding practices before finalizing any medical coding/billing documents.
