ICD-10 Code Families
Complete code families applicable to A04.72
When to use each related code
| Description | When to use |
|---|---|
| Infection causing diarrhea and colitis. | Use for positive C. difficile test and symptoms like diarrhea after antibiotic use. Consider risk factors like hospitalization. |
| Antibiotic-associated diarrhea not due to C. diff. | Use when diarrhea occurs after antibiotic use but C. difficile test is negative. Exclude other causes. |
| Inflammation of the colon from various causes. | Use for colon inflammation with symptoms like abdominal pain, diarrhea, and blood in stool. Specify cause if known (e.g., ulcerative colitis). |
Best-practice checklist
- ✓C. difficile infection diagnosis documentation:
- ✓Document toxin assay results (PCR or EIA).
- ✓Specify CDI onset: hospital-acquired or community-acquired.
- ✓Describe symptoms: diarrhea, abdominal pain, fever.
- ✓Include severity: mild, moderate, severe, fulminant.
- ✓Document treatment plan: antibiotics, fecal transplant.
Common pitfalls to avoid
Coding C. difficile without specifying if it's initial or recurrent episode leads to inaccurate severity and quality reporting. Use appropriate ICD-10 codes (A04.71, A04.72).
Failing to document CDI as present on admission (POA) impacts hospital-acquired infection reporting and reimbursement. Accurate POA indicator is crucial for compliance.
Coding CDI without proper clinical documentation like positive lab tests or imaging studies supporting the diagnosis can trigger claim denials and audits. Ensure complete medical record.
Best-practice tips
- 01Diagnose CDI accurately: PCR test preferred over toxin tests.
- 02Document CDI severity: Include symptoms, lab results, & treatment.
- 03Implement contact precautions: Gown & gloves for all patient contact.
- 04Prescribe appropriate antibiotics judiciously: Avoid unnecessary use.
- 05Promote antimicrobial stewardship: Track & review antibiotic usage.

Ready-to-paste narrative
Patient presents with complaints consistent with Clostridioides difficile infection (CDI, C. diff), including frequent watery diarrhea, abdominal pain, and cramping. Onset of symptoms began approximately [Number] days ago following recent antibiotic therapy with [Antibiotic Name and Dosage]. Patient reports [Number] bowel movements per day with stool characterized as loose and watery, sometimes containing mucus. Patient denies blood in stool. Abdominal examination reveals mild tenderness to palpation in the [Location] quadrant. The patient exhibits signs of dehydration including dry mucous membranes and decreased skin turgor. Vital signs show a temperature of [Temperature], heart rate of [Heart Rate], blood pressure of [Blood Pressure], and respiratory rate of [Respiratory Rate]. Laboratory tests ordered include a C. difficile toxin assay and complete blood count (CBC) to assess for leukocytosis. Given the patient's clinical presentation and recent antibiotic use, the presumptive diagnosis is C. difficile colitis. Treatment initiated with oral [Medication Name and Dosage]. Patient education provided regarding infection control precautions, including hand hygiene and environmental disinfection. Plan to monitor patient's clinical response to therapy and adjust treatment as needed. Differential diagnoses considered include antibiotic-associated diarrhea, inflammatory bowel disease, and irritable bowel syndrome. ICD-10 code A04.7 assigned. Follow-up scheduled in [Number] days to reassess symptoms and treatment efficacy.
Common questions and answers
What are the latest evidence-based treatment guidelines for recurrent Clostridioides difficile infection (CDI) in adults?+
Recurrent Clostridioides difficile infection (CDI) poses a significant clinical challenge. Current evidence-based guidelines from organizations like the IDSA and SHEA recommend a tiered approach to treatment based on recurrence number and severity. For a first recurrence, fidaxomicin or a pulsed-tapered vancomycin regimen is recommended. For second or further recurrences, bezlotoxumab is an option for preventing further recurrence, especially in high-risk individuals. Fecal microbiota transplantation (FMT) is now considered a first-line therapy for recurrent CDI and has demonstrated high efficacy rates. Explore how FMT is changing the landscape of recurrent CDI treatment and consider implementing these updated guidelines in your practice. For patients with severe or fulminant CDI, surgery may be necessary. Learn more about the role of surgery in managing complicated CDI.
How can I differentiate Clostridioides difficile (C. diff) infection from other causes of antibiotic-associated diarrhea in my patients?+
Differentiating Clostridioides difficile (C. diff) infection from other causes of antibiotic-associated diarrhea requires a comprehensive approach. While antibiotic-associated diarrhea can be caused by various factors, including disrupted gut microbiota, C. diff infection presents with distinct clinical features. Consider the patient's antibiotic exposure, the onset and duration of diarrhea, and the presence of other symptoms such as abdominal pain, fever, or leukocytosis. Laboratory testing, specifically stool testing for C. difficile toxins (using either a nucleic acid amplification test or glutamate dehydrogenase followed by toxin testing), is crucial for confirming the diagnosis. Explore the latest diagnostic algorithms for C. diff infection, including the importance of toxin testing and the limitations of PCR alone. Consider implementing a standardized diagnostic pathway for antibiotic-associated diarrhea to accurately identify and manage C. diff infections in your practice.
What are the best strategies for preventing Clostridium difficile (C. diff) transmission in hospital settings and long-term care facilities?+
Preventing Clostridioides difficile (C. diff) transmission requires a multi-faceted infection control approach. Key strategies include judicious antibiotic prescribing practices, early and accurate diagnosis of C. diff, prompt isolation of infected patients in private rooms or cohorts, strict adherence to hand hygiene protocols with soap and water (alcohol-based sanitizers are not effective against C. diff spores), thorough environmental cleaning and disinfection with sporicidal agents like bleach, and education of healthcare staff and patients about C. diff prevention. Consider implementing an antimicrobial stewardship program to optimize antibiotic use and minimize the risk of C. diff. Learn more about the role of environmental contamination in C. diff transmission and explore best practices for effective disinfection strategies.
