ICD Code R09.02

ICD code R09.02 is a medical classification used to denote hypoxemia, which refers to an abnormally low level of oxygen in the blood. This condition can be indicative of various underlying health issues, such as respiratory disorders, cardiovascular problems, or other systemic conditions that impair oxygen delivery or utilization. Accurate coding of hypoxemia is crucial for healthcare providers to ensure proper documentation, treatment planning, and reimbursement processes within the healthcare revenue cycle.

1. Low Blood Oxygen Levels: Use the ICD code when there is a documented measurement of low blood oxygen levels, typically identified through arterial blood gas analysis or pulse oximetry, showing oxygen saturation below normal ranges.

2. Shortness of Breath: Documented episodes of dyspnea or difficulty breathing that are not attributed to other conditions and are consistent with decreased oxygen levels.

3. Cyanosis: Presence of bluish discoloration of the skin, lips, or nail beds, indicating insufficient oxygenation of the blood.

4. Fatigue and Weakness: Persistent fatigue or weakness that correlates with low oxygen levels and cannot be explained by other medical conditions.

5. Confusion or Altered Mental Status: Episodes of confusion, disorientation, or altered mental status that are linked to inadequate oxygen supply to the brain.

6. Tachycardia: An increased heart rate that occurs as a compensatory mechanism in response to low oxygen levels in the blood.

7. Respiratory Distress: Signs of respiratory distress, such as rapid breathing, use of accessory muscles, or nasal flaring, associated with low oxygen saturation.

8. Underlying Respiratory Conditions: Use the code when hypoxemia is a complication or symptom of underlying respiratory conditions such as chronic obstructive pulmonary disease (COPD), asthma, or pneumonia.

9. Post-Surgical or Trauma-Related Hypoxemia: Documented cases of hypoxemia occurring after surgery or trauma, where oxygen levels are monitored and found to be below normal.

10. Chronic Hypoxemia: Long-term low blood oxygen levels that are documented over time and require ongoing management or intervention.

For the ICD code R09.02 (Hypoxemia), the relevant CPT codes that may be applicable for treatment and diagnostic procedures include:

1. 94760 - Noninvasive ear or pulse oximetry for oxygen saturation; single determination.

2. 94761 - Noninvasive ear or pulse oximetry for oxygen saturation; multiple determinations (e.g., during exercise).

3. 94762 - Continuous overnight monitoring of oxygen saturation.

4. 94010 - Spirometry, including graphic record, total and timed vital capacity, expiratory flow rate measurement(s), with or without maximal voluntary ventilation.

5. 94060 - Bronchospasm evaluation: spirometry as in 94010, before and after bronchodilator (aerosol or parenteral).

6. 94620 - Pulmonary stress testing; simple (e.g., 6-minute walk test, stair climbing, oximetry).

7. 94621 - Pulmonary stress testing; complex (including measurements of CO2 production, O2 uptake, and electrocardiographic recordings).

These CPT codes are often used in conjunction with the diagnosis of hypoxemia to assess and manage the patient's condition effectively. Always ensure that the selected CPT codes align with the specific services provided and adhere to payer guidelines.
