Explanation

Premium for incising an abscess or haematoma as the only procedure, under general anaesthetic, in an operating room (not an ED).

What it covers

E515 is a percentage add-on for incision of an abscess or haematoma performed as the sole procedure under general anaesthetic in an operating room, but not in an emergency department or emergency department equivalent (M1).

It is payable to Z102, Z172, Z105, Z107, Z541, Z574 and Z758 (M1).

Billing rules

• Only with Z102, Z172, Z105, Z107, Z541, Z574 or Z758 (M1).
• The incision must be the sole procedure (M1).
• Must be under general anaesthetic, which means any anaesthesia except topical or local infiltration (M1, GP3).
• Must be in an operating room, not in an emergency department or ED equivalent (M1). An ED equivalent is an office, urgent care centre, walk-in or extended hours clinic that only sees patients without pre-arranged appointments (GP3).

Often billed with

• Z105 perianal, Z107 ischiorectal or pilonidal, Z102 and Z172 subcutaneous abscess under general anaesthetic (M1).

Common rejections

• ADF: OHIP describes this as 'Corresponding procedure invalid, omitted or paid at zero': E515 was billed without one of its listed base codes (Z102, Z172, Z105, Z107, Z541, Z574, Z758) being paid (M1).
