1. Can I bill Medicare for pulse ox interpretation in the ED (94760-94762)?
The simple answer is no. Here are the reasons why:
2. Can I bill non-Medicare patients for pulse ox interpretation in the ED?
The answer is still no. The above answers are from CMS, which only governs Medicare claims. But CPT policy covers all claims utilizing CPT codes and nomenclature. Per the CPT Information Services:
“From a CPT Coding perspective, the purpose of codes 94760 and 94762 is to identify that the physician owns the equipment used for the oximetry and performed the interpretation of the results. Therefore, if the physician does not own the equipment used to perform the ear pulse oximetry, it would not be appropriate to report code 94760 or 94762 to identify his or her services. Interpretation of the ear or pulse oximetry results performed by the physician when the equipment is not owned by the physician (e.g., performed on hospital-owned equipment) is considered part of the medical decision making component of the evaluation and management (E/M) service codes."
3. If the pulse ox interpretation is considered part of the E/M service, can I also count it when determining the MDM level (Medical Decision Making)?
The purpose of MDM is to represent the complexity of the physician’s thought processes in evaluating and managing a given patient’s present, past, and potential medical problems. In many emergency departments, oxygen saturation is documented as a part of the intake process for every patient. The solitary act of recording the pulse ox reading by the nursing staff might not seem to communicate any added complexity of thought by the ED physician. For example, no additional medical complexity exists if a patient has a pulse ox documented with an isolated ankle sprain and no oxygen saturation coupled medical conditions are present.
While the 2023 E/M guidelines state the pulse on cannot be used when calculating the data element of the MDM (“For the purposes of data reviewed and analyzed, pulse oximetry is not a test.”), it may be reasonable to take pulse ox interpretation into account when considering the Nature and Complexity of Problems Addressed (COPA) in cases where the patient’s medical condition(s) warrants the ED physician using the saturation reading as part of the diagnostic/management process: for shortness of breath, chest pain, history of respiratory ailments, a child with bronchiolitis, etc. In such cases, it would be prudent to document the relevance of pulse ox interpretation in the medical record.
