10060 - Incision and drainage of abscess (eg, carbuncle, suppurative hidradenitis, cutaneous or subcutaneous abscess, cyst, furuncle, or paronychia); simple or single
26010 - Drainage of finger abscess; simple
I think you want to get to the highest specificity here. I would go with 26010 if all they did was pop it and let it drain out then irrigate it with saline.
