O0110B1a: Treatment: Oxygen Therapy - On Admission

Step-by-Step Coding Guide for Item Set O0110B1a: Treatment: Oxygen Therapy - On Admission

1. Review of Medical Records

Objective: To identify and verify the resident's use of oxygen therapy during the 7-day look-back period. Key Points:

• Thoroughly review the resident’s medical chart, focusing on physician's orders, nursing notes, and respiratory therapy records.
• Look for documentation indicating the initiation of oxygen therapy, including the date started and any changes in the administration details (flow rate, delivery method).

2. Understanding Definitions

Objective: Clarify what constitutes oxygen therapy and when it is coded on admission. Key Points:

• Oxygen therapy involves administering oxygen at concentrations greater than ambient air (21%) to improve oxygenation.
• "On Admission" refers to oxygen therapy started within the 7-day look-back period from the date of the MDS assessment.

3. Coding Instructions

Objective: Accurate coding of O0110B1a based on CMS guidelines. Key Points:

• Code as "1" if oxygen therapy was initiated at any time during the 7-day look-back period.
• Include any form of oxygen delivery (nasal cannula, mask, etc.) prescribed by a healthcare professional.

4. Coding Tips

• Ensure the therapy was specifically ordered by a physician or authorized healthcare provider.
• Review for any temporary discontinuations but code based on initiation during the look-back period.

5. Documentation

Objective: Ensure comprehensive and precise documentation of oxygen therapy. Key Points:

• Document the specific reason for oxygen therapy, including underlying conditions (COPD, pneumonia, etc.).
• Record the delivery method, flow rate, and duration of therapy.

6. Common Errors to Avoid

• Failing to code oxygen therapy if it was started prior to but continued into the 7-day look-back period.
• Overlooking physician orders or notes indicating the medical necessity for oxygen therapy.

7. Practical Application

Example Scenario: A resident was admitted to the facility with chronic obstructive pulmonary disease (COPD) exacerbation and prescribed 2 liters per minute of oxygen via nasal cannula upon admission. The therapy was documented in the physician's orders and nursing notes, including the start date, which falls within the 7-day look-back period.
