Documented but Unsupported: UTI, an Unsigned Note, and a Record About to Be Billed
Community hospital, inpatient. Ms. L, 81, is admitted from a skilled nursing facility with confusion and poor oral intake. Admission H&P: 'altered mental status, dehydration, probable UTI.' IV fluids are started. Urinalysis shows 2+ WBC but no nitrite and no bacteria; urine culture is negative at 48 hours; no antibiotics are ordered. The hospitalist's discharge summary, dictated five days later, reads 'UTI, dehydration, resolved.' The MAR and nursing notes contain no antibiotic administration. A physician assistant's unsigned day-2 progress note adds 'AKI stage 1.' Creatinine is 1.1 on admission and 1.0 at discharge.
1. For each condition named in the record, state whether it can be coded as documented and why.

Dehydration - code it. Documented by the attending, supported by poor oral intake and IV fluid resuscitation, and it affected management.
UTI - hold; do not code until clarified. The diagnosis is documented, but coded conditions must be supported by the record and must require or affect care. Against it: negative culture at 48 hours, no nitrite or bacteria, no antibiotics, no urinary symptoms. The 'probable' qualifier is not the obstacle (in the inpatient setting, a diagnosis documented as probable/suspected is coded as if established) - the contradiction is. A diagnosis contradicted by the clinical picture requires a query, not silent acceptance and not silent deletion.
AKI stage 1 - cannot code. Two independent barriers: (1) it appears only in an unsigned PA note, and unauthenticated entries are not a source for code assignment; (2) the creatinine is 1.1 falling to 1.0, giving no clinical support.
Altered mental status is a symptom; code it only if it remains unexplained at discharge (it does here unless the provider attributes it to dehydration).
2. Draft the query text you would send for the UTI discrepancy and explain why each element of your wording is there.

Dr. ___: The record contains conflicting information about a urinary tract infection. Findings consistent with infection: 2+ WBC on urinalysis and your documentation of 'probable UTI' and 'UTI, resolved.' Findings not consistent: negative urine culture at 48 hours, no nitrite or bacteria on urinalysis, no antibiotics administered, and no urinary symptoms documented. Please clarify which of the following best describes the patient's clinical status: (a) Urinary tract infection - if so, please document the clinical basis and whether it was present on admission; (b) Asymptomatic bacteriuria; (c) Neither - the WBCs are attributable to another cause; (d) Unable to determine.
Why it is written this way:
- Both sides of the evidence are stated, so the physician is not steered to a preselected answer.
- Options include 'unable to determine' and an open option, which is the hallmark of a non-leading query.
- No code numbers, DRG references, or reimbursement language appear; the query is clinical, not financial.
- Present-on-admission is requested because a UTI that develops after admission carries different reporting and quality implications.
- It is a single, focused question with discrete answers, so the response is usable in the record.
3. The PA's note is never authenticated and the physician does not answer the query before the bill must drop. What do you do?
Read the worked answer
- Do not code the UTI. With no answer, the only defensible position is to code what the authenticated record supports. Document in the coding record that a query was issued, the date, and that no response was received.
- Do not code the AKI - the entry is unauthenticated and the labs contradict it.
- Escalate, do not just absorb it. Route the unanswered query and the unsigned note to CDI/the physician advisor and then to medical staff per the facility's escalation policy. Authentication deadlines are governed by medical staff bylaws and accreditation standards, not by the coding schedule.
- Do not hold the claim indefinitely waiting for a note that may never be signed; bill the supported conditions and add the clarified diagnosis later through the facility's late-entry/corrected-claim process if the record is amended.
- Treat the pattern as a documentation issue. Recurring copy-forward of 'probable UTI' into the discharge summary and missing authentications are the root causes; that is a CDI and medical staff education item, not a coder workaround.
