C1310A: Acute Onset Mental Status Change, Step-by-Step

Step-by-Step Coding Guide for Item Set C1310A: Acute Onset Mental Status Change

1. Review of Medical Records

• Objective: Identify and document any acute onset of mental status change in the resident.
• Steps:
  1. Collect Relevant Documentation: Gather medical records, nursing notes, and incident reports.
  2. Identify Changes: Look for documentation indicating sudden changes in mental status.
  3. Consult with Healthcare Providers: Verify with attending healthcare providers and staff about any noted acute changes in mental status.

2. Understanding Definitions

• Acute Onset: A sudden and noticeable change in the resident's mental status, which is a departure from their baseline cognitive function.
• Mental Status Change: This may include confusion, disorientation, altered level of consciousness, or significant behavioral changes.

3. Coding Instructions

• Steps:
  1. Review Records: Confirm the documentation of an acute onset mental status change.
  2. Determine Timing: Ensure that the change occurred acutely, rather than gradually over time.
  3. Select Appropriate Code: Code the presence of acute onset mental status change in item C1310A of the MDS.
  4. Accurate Entry: Ensure that the information is correctly entered into the MDS with all relevant details.

4. Coding Tips

• Consistency: Ensure consistency across all documentation regarding the acute onset of mental status change.
• Detailed Notes: Include specific observations and descriptions of the mental status change.
• Collaboration: Work closely with the interdisciplinary team to ensure accurate and thorough documentation.

5. Documentation

• Required:
  • Incident Reports: Any reports that document the acute onset of mental status changes.
  • Nursing Notes: Detailed nursing notes that describe the change in mental status and any interventions.
  • Physician Documentation: Notes from physicians that detail the diagnosis and observations of mental status change.
  • Care Plans: Updates to the resident’s care plan to reflect the change and any interventions or treatments.

6. Common Errors to Avoid

• Misidentifying Onset: Ensure the change is acute and not a gradual decline or chronic condition.
• Incomplete Documentation: Avoid missing critical details in documentation that describe the onset and nature of the mental status change.
• Lack of Verification: Confirm the change with multiple sources and document accordingly to avoid misclassification.

7. Practical Application

• Example:
  • Resident Profile: Jane Doe, an 85-year-old female, previously oriented and alert, suddenly becomes confused and disoriented.
