Section 01
Category I, II, and III
Category I is the main procedure and E/M set. Category II is optional supplemental tracking. Category III is temporary codes for emerging technology. Official descriptors and sequencing rules live in AMA CPT materials your organization licenses.
Section 02
Lookup tools versus clinical assignment
A lookup box answers “what is 99214.” Automation answers “given this note, is 99214 supported.” Confusing the two is how thin affiliate lookup sites rank and why a software vendor should keep a separate explainer URL.
