CCDS Pressure Ulcers and Wound Care Documentation 2 — Questions and Answers
Question 1: What characterizes a deep tissue pressure injury (DTPI) and how does it differ from a staged pressure ulcer?
- It is equivalent to a Stage 4 ulcer with visible bone exposure
- It presents as persistent discoloration of intact or non-intact skin from pressure, with its own distinct ICD-10-CM code (Correct answer)
- It describes any wound with necrotic tissue requiring debridement
- It is a surgical wound that becomes infected postoperatively
Correct answer: It presents as persistent discoloration of intact or non-intact skin from pressure, with its own distinct ICD-10-CM code
DTPI presents as persistent non-blanchable discoloration (deep red, maroon, or purple) of intact or non-intact skin and has a dedicated ICD-10-CM code separate from Stage 1–4 pressure ulcers.
Question 2: When a patient has pressure ulcers at multiple different anatomic sites, what is the correct coding approach?
- Code only the most severe pressure ulcer to simplify the record
- Code each pressure ulcer separately with its own site-specific and stage-specific code (Correct answer)
- Use a single 'multiple pressure ulcers' unspecified code
- Code only ulcers that received active treatment during the stay
Correct answer: Code each pressure ulcer separately with its own site-specific and stage-specific code
Each pressure ulcer at a distinct anatomic location is assigned its own ICD-10-CM code reflecting the specific site and stage, as ICD-10-CM provides individual codes for each location.
Question 3: What is the CDI specialist's role in skin substitute graft documentation for wound care procedures?
- Verify documentation of the specific graft product and wound site to support accurate ICD-10-PCS procedure coding (Correct answer)
- Defer entirely to the surgical department for all graft-related documentation
- Verify only that informed consent was signed before the procedure
- Review only the patient's insurance coverage for graft approval
Correct answer: Verify documentation of the specific graft product and wound site to support accurate ICD-10-PCS procedure coding
Skin substitute graft procedure codes in ICD-10-PCS vary by the specific product used and the anatomic site of application, requiring CDI to verify both elements are documented.
Question 4: How does the etiology of a lower extremity ulcer affect its ICD-10-CM code assignment?
- Venous and arterial ulcers are coded identically under 'chronic skin ulcer'
- Etiology (venous vs. arterial vs. diabetic) determines the code category and requires documentation of the underlying vascular condition (Correct answer)
- Only wound size and depth determine the code, not etiology
- Etiology affects only the treatment plan, not the diagnosis code
Correct answer: Etiology (venous vs. arterial vs. diabetic) determines the code category and requires documentation of the underlying vascular condition
Venous, arterial, and diabetic lower extremity ulcers have distinct ICD-10-CM code categories, and the underlying vascular or metabolic diagnosis must be documented for accurate code assignment.
Question 5: What documentation is required for accurate wound debridement procedure coding in ICD-10-PCS?
- The deepest tissue level debrided and the method used (excisional vs. non-excisional) (Correct answer)
- Only the wound dimensions before and after debridement
- Only whether the debridement was performed in the operating room
- The total number of debridement sessions performed during the stay
Correct answer: The deepest tissue level debrided and the method used (excisional vs. non-excisional)
ICD-10-PCS debridement coding requires documentation of the deepest tissue level reached (skin, subcutaneous, muscle, or bone) and the method (excisional vs. non-excisional) to select the correct code.
Question 6: Which wound-related condition is a CMS-designated hospital-acquired condition (HAC) that CDI must monitor closely?
- Stage 3 and Stage 4 pressure ulcers acquired after admission and not documented as POA (Correct answer)
- Any skin breakdown that develops during the hospital stay regardless of cause
- Venous stasis ulcers that worsen despite treatment during the stay
- Surgical incision sites requiring additional wound care beyond routine management
Correct answer: Stage 3 and Stage 4 pressure ulcers acquired after admission and not documented as POA
CMS designates Stage 3 and Stage 4 pressure ulcers that are not POA as HACs, resulting in no additional reimbursement for treatment costs and impacting quality reporting.
