Question: Are there query opportunities based on the scenario stated above?
According to the Wound Care nurse, the patient has a stage 3 pressure ulcer to left buttock with deep tissue injury to the left heel. Note that the physical exam mentions, “wound to left buttocks, most likely pressure ulcer and redness to the left heel” with the discharge summary indicating, “Wound to left buttocks and heel”. The provider did not carry the diagnosis of likely pressure ulcer of the left buttock to the discharge summary or indicate any other specific diagnosis of the left heel.
According to the ICD-10-CM Official Guidelines for Coding and Reporting, Section III. C. Uncertain Diagnosis: If the diagnosis documented at the time of discharge is qualified as “probable”, “suspected”, “likely”, “questionable”, “possible”, “still to be ruled out”, “compatible with” “consistent with” or other similar terms indicating uncertainty, code the condition as if it existed or was established.
The cardiology consult states patient has Heart Failure with EF of 24%. Pt noted with BLE edema and mild pulmonary edema, however continued with the home med dose of PO Lasix during stay and to discharge. UC noted E. coli with Bactrim ordered and given through discharge.
- Possible Query opportunities:
- Query for Documentation Clarification: Left Buttock Wound Type; Left Heel Wound Type
- Query for HF Type
- Query for Documentation Clarification: Alzheimer’s Dementia
- Query for DM with Hyperglycemia
- Query for Obesity specificity
- Query for UTI due to E.coli
(Be alert that prioritization of query submission may be needed)

CDI Educational Tips:
- Code assignment for the stage of the pressure ulcer can be assigned from nursing documentation, however the associated diagnosis of pressure ulcer must be documented by the patient’s provider per OCG 1.B.14 ‘Documentation by Clinicians Other than the Patient’s Provider’
- Monitor wound care notes from nursing and provider notation closely for both conflicting and continuance of documentation through discharge
- Monitor for POA for pressure ulcers or injuries
- Monitor chronic illnesses with acute treatment while admitted
- Confirm any labs for possible sepsis
- Monitor cultures for linking results and treatments to a diagnosis
- Be alert for functional quadriplegia when contractures are noted; review carefully provider documentation and ancillary notes for support of nonfunctional status
