    Write a function that validates a patient's multi-metric health code from their wearable device, where each digit represents a specific health threshold, by ensuring the occurrence count of each digit does not exceed its own value to prevent false alerts in the monitoring system. For example, in a health code where '3' appears four times, it would be invalid as it exceeds its own value (3), potentially indicating a monitoring system malfunction.
