    Write a function that validates a patient monitoring code by ensuring each digit's occurrence frequency in the code does not exceed the digit's actual value, where each digit represents a vital sign threshold. The monitoring system uses this validation to prevent false alarms by confirming that no individual health parameter threshold appears more times than its designated safety limit.
