I am scheduled to take my first certification exam next week. I used the 2020 HCS-D Study Guide. Any advice?
Here are are few suggestions for you:
Be sure to reference the Tabular list -- don't code from the Alphabetic Index
Know when it's safe to assume a causal relationship between two conditions
Read the includes, excludes, and other instructional notes in the Tabular List
Watch for missing or incorrect 4th, 5th, 6th, and 7th characters
Be careful of NOS codes when specific information is available
Check for a bilateral choice before coding right and left (if patient has a bilateral condition)
Check for combination codes
I hope that's helpful! Wishing you all the best on your exam.
