Destroys tissue using a small instrument with a cautery needle connected to a monopolar electric source. As the needle touches the tissue it is burned away.

58
Q

Superficial wounds that primarily involve epidermis, dermis, and subcutaneous tissue without deep sutures. If only adhesive strips are used to closed report only an E/M code

65
Q

Intermediate wound repair

A

Repair of epidermis, dermis, subcutaneous tissue requires layered closure of one or more of the subcutaneous tissues or non-muscle fascia. Includes limited undermining. Can also be used for single layer wound requiring extensive cleaning of foreign material

66
Q

Complex wound repair

A

Repair of wounds with at least one of the following: exposure of bone, cartilage, tendon, or named neurovascular structure; debridement of wound edges, extensive undermining, involvement of free margins of helical rim, vermilion border, nostril rim, or retention sutures. Necessary prep includes creation of limited defects, debridement of complicated lacerations or avulsions.

67
Q

Wound repair reporting tips

A

Measured in cm. Group by type of repair and anatomical site. Add same site and type together. List complicated to least complicated and add modifier 59.

68
Q

Advancement flap

A

Undermining or freeing up tissue surrounding a defect creates an advancement flap. Tissue is now free to move forward into the defect and be sutured to the other wound edge.

69
Q

Allograft

A

Skin transplanted from one person to another who is not genetically identical

70
Q

Autograft / autologous

Q

Derma-fascia-fat grafts

A

Service performed to smooth out blemishes created secondarily to surgically created defects or atrophy.

73
Q

Double pedicle flap

A

74
Q

Free fascia graft

A

Requires elevation and transfer of the fascia with micro vascular anastomosis. If subsequently covered with skin graft the skin graft is reported separately.

75
Q

Full thickness graft

A

Graft composed of epidermis and dermis. Cut with scalpel and placed over defect and sutured into place.

76
Q

Heterograft

A

Graft material transferred between species. Functions as a biological dressing.

Graft from same species but not genetically identical. Lasts about 10 days. Promotes growth of new skin. Usually used to cover large burns.

78
Q

Rotation flap

A

Incision made to create a curvilinear flap contiguous with the defect. When flap is dissected free it is rotated over the defect and sutured into place. Defect created by flap is sutured or grafted as needed.

79
Q

Split thickness graft

A

Composed of epidermis and small portion of the dermis.

80

If multiple sites are destroyed more than one code is required. Not coded based on therapy type but by the tissue destruction procedure.

86
Q

Mohs micrographic surgery

A

Unique procedure with surgeon acting as pathologist as well. Tissue is removed divided into tissue blocks and checked for positive margins. If positive another portion of the tumor is removed and tested. Each time the surgeon returns is a stage. If skin defect repair is needed it is coded separately. Coded by stages and tissue blocks.

87
Q

Lumpectomy
