O0110 on the OASIS item lookup
O0110. For O0110C - Special Treatments, Procedures, and Programs; Oxygen therapy: If the oxygen is ordered PRN, is that considered intermittent because it is ordered PRN or only if the patient uses it PRN on the day of assessment?
The intent of O0110 - Special treatments, Procedures, and Programs identifies if any of the listed special treatments, procedures, and programs apply to the patient. O0110 should be completed based on a comprehensive assessment that occurs at SOC/ROC or discharge. Regardless of how the oxygen is ordered (i.e., continuously or intermittently), apply the OASIS specific definitions in determining whether oxygen is coded as continuous (delivered for ≥ 14 hours per day) or intermittent (oxygen was not delivered continuously for at least 14 hours per day).

O0110. For Special Treatments, Procedures, and Programs: Non-invasive Mechanical Ventilator O0110G2 - BiPAP and O0110G3 - CPAP, are these only selected if the BiPAP/CPAP was used during the assessment window? Sometimes a treatment may be ordered and available but the patient will refuse to wear it.
If the BiPAP or CPAP is part of the patient’s current care/treatment plan, then mark O0110G1 - Non-Invasive Mechanical Ventilator and O0110G2 - BiPAP or O0110G3 - CPAP.

O0110. We know that we code O0110 - Special Treatments, Procedures, and Programs based on what is part of the current care/treatment plan at the time of the assessment. Can CMS provide further clarification on how to code O0110O1 - IV Access and O0110O4 - IV Access; Central if a PICC line is being pulled during the discharge assessment?
The intent of O0110 - Special Treatments, Procedures, and Programs is to identify any special treatments, procedures, and programs that apply to the patient. Check all treatments, programs and procedures that are part of the patient’s current care/treatment plan at the time of assessment, even if not used during the time of assessment for SOC/ROC (or discharge). This includes a PICC line that is being discontinued at the time of the assessment.

Since the February 2026 release: July 2026 CMS Quarterly OASIS Q&As
If a patient is receiving radiation treatment for a condition other than cancer, such as low dose radiation for osteoarthritis, should O0110B1 - Special Treatments, Procedures, and Programs; Radiation be checked?
Each radiation treatment should be evaluated to determine its reason for use before coding it in O0110B1 - Special Treatments, Procedures, and Programs; Radiation. Check O0110B1 - Radiation, if any type of radiation is administered intermittently or via radiation implant for cancer treatment. Radiation treatment provided for reasons other than the treatment of cancer should not be considered when coding this item.
