M2003 Q160.5Category 4b - OASIS Data Items

M2003. A clinically significant medication issue is identified on a weekend, and the agency phones the physician on-call. The physician on-call responds with instructions for the agency to contact the primary care physician on Monday. Can the clinician select Response 1 - Yes; Physician or physician-designee was contacted by midnight of the next calendar day and prescribed/recommended actions were taken?

When completing M2003 - Medication Follow-up, if the physician/allowed practitioner or physician designee responds by midnight of the next calendar day and there is a resolution to the clinically significant medication issue, Response 1 - Yes should be entered. In your scenario, you describe a situation where the physician was contacted and informed of the medication issue, but then due to the contacted physician’s unfamiliarity with the patient, you were directed to contact the primary care practitioner on Monday. In cases where the physician/allowed practitioner (or physician-designee) recommends an action that will take longer than the allowed time to complete, then Response 1 - Yes should be entered as long as by midnight of the next calendar day, and within the assessment timeframe the agency has taken whatever actions are possible to comply with the recommended action.

M2003 Q160.5.1Category 4b - OASIS Data Items

M2003. I am aware that in order to mark response 1 - Yes, the two-way communication AND prescribed/recommended actions must be completed by midnight of the next calendar day after the problem was identified. Does that “next calendar day” have to be within the 5 days after the SOC? That is, if the nurse finds a problem with the patient’s meds while completing the comprehensive assessment on day 5 after the SOC, and the physician is notified and the problems are resolved but not until day 6 after the SOC, (although it is within the one calendar day), can 1 - Yes be marked?

M2003 - Medication Follow-up, is only collected at the SOC and ROC. The item must be answered within the timeframe allowed at the SOC/ROC to ensure compliance with the Condition of Participation regarding the completion of the comprehensive assessment. If a problem is identified, the communication and completion of prescribed/recommended actions to the extent possible must occur by midnight of the next calendar day after identification and before the end of the allowed timeframe in order to answer 1 - Yes. If a medication issue is identified on day 5 after the SOC, the physician is contacted by midnight of the next calendar day and responds back with a plan to resolve the problem on day 6 after the SOC, this 2-way communication could not be captured at the SOC.

M2003 Q160.5.2Category 4b - OASIS Data Items

M2003. On my Tuesday admission visit, my patient reported a new rash which had continually worsened since initiating a new antibiotic 4 days ago. I considered this a potential clinically significant medication issue and contacted the physician the same day. The next morning the physician returned my call to report he had called in a new antibiotic prescription, and to notify the patient to discontinue the old med and start with the new. I notified the patient and family that day and the son agreed to pick up the new medication. On the Thursday visit the patient says they are less itchy and uncomfortable since they started the new medication last night. The rash is still present and therefore this issue has not been resolved, although considerably less severe. How do I code M2003 - Medication Follow-up?

M2003 - Medication Follow-up identifies if potential or actual clinically significant medication issues identified though the drug regimen review were communicated to the physician/allowed practitioner (or physician-designee) with prescribed/recommended actions completed by midnight of the next calendar day. In the scenario described, the communication occurred, and the prescribed/recommended action (communicate medication change to patient) was completed prior to midnight of the next calendar day after the issue was identified. Code M2003 as 1 - Yes. It is not necessary for the issue, in this scenario the rash, to be resolved by midnight of the next calendar day, as long as the physician communication and completion of the prescribed/recommended actions were completed.

M2003 Q160.6.2Category 4b - OASIS Data Items

M2003 & M2005. Multiple clinically significant medications issues were identified as I completed the SOC assessment. Only one was resolved by midnight of the next calendar day. How do I answer M2003 – Medication Follow-up and then M2005 – Medication Intervention?

In order to select response 1 - Yes to M2003 - Medication Follow-up, the physician must have been notified by midnight of the next calendar day regarding all clinically significant medication issues that were identified during the SOC/ROC comprehensive assessment. In addition to the physician notification, you must have completed any prescribed/recommended actions to the extent possible by midnight of the next calendar day to answer 1-Yes. In order to select response 1 - Yes for M2005 - Medication Intervention, all clinically significant medication issues that were identified at the time of or at any time since the SOC/ROC must have been resolved in the same manner as stated above.

M2003 Q160.6.3Category 4b - OASIS Data Items

M2003 & M2005. What is meant by “communication can be directly to/from the physician, or indirectly through physician’s office staff on behalf of the physician, in accordance with the legal scope of practice”? Can the physician’s secretary be considered office staff if they speak directly to the physician with the clinician’s questions and then gives the information directly back to the clinician?

The reference to “in accordance with the legal scope of practice” refers to the State requirements defining who can take orders from physicians. Each HHA should have a policy and procedure consistent with State law that describes who can take orders from the physician. It is important to understand that all orders must come from the physician/allowed practitioner and eventually be signed by the physician/allowed practitioner.

M2003 Q160.6.4Category 4b - OASIS Data Items

M2003 & M2005. When completing M2003 - Medication Follow-up or M2005 Medication Intervention, does the midnight of the next calendar day “clock” start when the assessing clinician identifies the clinically significant medication issue, even if the issue is identified, for instance, on Day 2 of the episode?

M2003 - Medication Follow-up and M2005 - Medication Intervention ask if two-way communication and completion of any prescribed/recommended actions occurred by midnight of the next calendar day when a clinically significant issue is identified. For M2003, the timeframe is “by midnight of the next calendar day” from the time the potential clinically significant medication issue was identified and within the Start of Care (SOC) or Resumption of Care (ROC) comprehensive assessment timeframe. For M2005, the timeframe is “by midnight of the next calendar day” each time a potential clinically significant medication issue was identified at the time of, or at any time since, the most recent SOC/ROC assessment.
