Pressure Ulcers and Wound Care Documentation Flashcards

A patient with a Stage 3 pressure ulcer on admission has the wound worsen to Stage 4 during hospitalization. How should the CDI specialist query this scenario?

Answer: Query to clarify whether the Stage 4 ulcer was present on admission or developed/worsened during the stay

The CDI specialist must clarify POA status because worsening from Stage 3 to Stage 4 may indicate a hospital-acquired condition, which has significant quality and reimbursement implications.

Which ICD-10-CM code category is used to identify a pressure ulcer that cannot be clinically staged because the wound base is covered by eschar?

Answer: L89 with a 9 suffix indicating unstageable

Unstageable pressure ulcers, obscured by slough or eschar, are coded with the 9 suffix under the L89 category in ICD-10-CM.

A CDI specialist reviews documentation showing a sacral wound with 'full-thickness skin loss involving subcutaneous tissue but not bone or muscle.' Which pressure ulcer stage does this describe?

Answer: Stage 3

Stage 3 pressure ulcers involve full-thickness skin loss with visible subcutaneous fat, but bone, tendon, and muscle are not exposed.

When a wound care note describes 'serosanguineous drainage, moderate amount, periwound erythema' for a pressure ulcer, which documentation element is most important for the CDI specialist to verify is also captured by the physician?

Answer: Clinical diagnosis of wound infection or cellulitis if clinically present

Periwound erythema and drainage may indicate infection or cellulitis; the physician must document a clinical diagnosis to support coding of a complication.

For DRG reimbursement purposes, which comorbid condition most significantly increases the complexity of a pressure ulcer admission?

Answer: Osteomyelitis underlying the pressure ulcer

Osteomyelitis underlying a pressure ulcer is a major complication/comorbidity (MCC) that can shift the DRG to a significantly higher-paying tier.

A patient is admitted with a heel wound that has been present for two months. The physician documents 'heel ulcer, etiology unclear.' What should the CDI specialist do?

Answer: Query the physician to clarify whether it is a pressure ulcer, arterial ulcer, diabetic ulcer, or other type

Etiology drives ICD-10-CM code selection for heel wounds, so the CDI specialist must query for clarification to ensure accurate coding and appropriate DRG assignment.

Which of the following best describes the role of the CDI specialist when reviewing MDS documentation for pressure ulcers in a skilled nursing facility (SNF) context?

Answer: Ensure MDS Section M accurately reflects current pressure ulcer stage for PDPM case-mix grouping

In SNF settings, accurate MDS Section M pressure ulcer staging is critical because it directly impacts PDPM reimbursement through nursing case-mix classification.
