Which code indicates home care due to reduced mobility?

• A. Z79.3
• B. Z74.09
• C. Z85.51
• D. Z38.62

Answer: (B)

The main idea is that some encounters are about needs for care rather than a diagnosis, so we use Z codes to document those factors. Within Z codes, the subsection that covers care at home is used when a patient requires assistance or supervision in the home. Reduced mobility leading to home care fits into this care-at-home category, and the decimal extension specifies the exact situation. The code Z74.09 is the one that most specifically represents home care needs stemming from mobility limitations, making it the best match for this scenario. The other options point to long-term medication use, personal cancer history, and pregnancy-related care, none of which describe needing home-based assistance due to reduced mobility.
