Ch 18 Integumentary System
How is the Integumentary System subsection formatted?
Anatomic site and category of procedure
Incision and Drainage codes are divided according to what?
First according to the condition for which it is being performed, and then by whether the procedure is simple or complicated.
Insertion of a needle into a lesion and withdrawal of the fluid inside.
True of False: All Incision and Drainage codes may be found within the Integumentary Subsection?
False. Use the index to find first the condition, then the location to determine where the most specific code is located.
When coding an abscess, when do you use the subterm "Skin"?
Only when there is no more specific location provided.
Removal of infected, contaminated, damaged, devitalized, necrotic, or foreign tissue from a wound.
Sharp and blunt dissection, curettement, scrubbing, and forceful irrigation are all examples of what procedure?
Are debridement codes applied to burn treatments?
No. For debridement of burned surfaces, use CPT 16000-16036.
What two factors are used to determine coding of wound debridement?
Depth of tissue removed and surface area of wound.
How do you calculate depth for multiple wound debridements?
Code each depth separately (do not sum.)
How do you calculate surface area for multiple wound debridements?
Sum the surface area of all wounds at the same depth.
What modifier is used when reporting multiple wound debridements of different depths?
-59 (Distinct Procedural Service)
Is debridement included as part of the surgical package or is it coded separately?
It depends on the surgical procedure. Code debridement only when it is greater than that included in the surgical package.
Do debridement codes include some E/M service, or must the E/M service always be reported separately?
Debridement includes E/M. Only report if E/M service is separately identifiable (modifier -25).
Local infiltration, metacarpal/digital block, or topical anesthesia are/are not included in the reimbursement for debridement services,
They are included. They are not separately payable.
Paring, shaving, excision, and destruction are types of what kind of treatment?

What elements are required to properly code lesion excision and destruction?
site, number, and size of excised lesions, as well as whether lesion is malignant and benign
If multiple lesions are being treated, how do you determine the order of coding?
Code the most complex lesion procedure first followed by the others using modifier -51 (multiple procedures performed).
If the code description includes multiple lesions, is modifier -51 necessary?
nonlayered closure (included in the codes for lesion excision).
layered closure (code separately per notes)
greater than layered closure (code separately per notes)
study of microscopic tissue changes
What modifier cannot be used with skin tag codes?

For what is the Lund-Brower Chart used?
To calculate the percentage of body surface involved in the burns of children.
