10060 vs 10061

Please help me determine the difference. My physician is stating she is charging a complex I&D because she placed packing. I am not sure that is the determining factor. Coder's Desk Reference states Report 10061 for complex or multiple cysts. Here is her procedure note.

I&D of Abscess: Date--4/20/2015

Op consent form signed by patient.

Local anesthesia with 1 % Lidocaine with epi

Pt. Prepped with betadine if not allergic to iodine, and rubbing alcohol.
Using sterile technique, I & D performed with #11 blade.
Abscess opened with hemostats and drained.
Packing gauze applied into wound.
Dressed with gauze.
Procedure well tolerated with no complications.

CPT guidelines aren't clear either.

Thank you!
