Inaccurate MDS Coding for Oxygen Use and Discharge Status

Thousand Oaks Post Acute, LlcThousand Oaks, California Survey Completed on 04-25-2025

Summary

The facility failed to ensure the Minimum Data Set (MDS) assessments were accurately coded for three residents, as required by facility policy and federal regulations. For one resident with chronic obstructive pulmonary disease (COPD) and a physician's order for supplemental oxygen, the MDS did not reflect the use of oxygen therapy, despite documentation in care plans, progress notes, and vital records indicating the resident received oxygen as needed during the assessment period. The MDS Coordinator confirmed the omission, stating that only the physician order and electronic medication administration record were referenced during the assessment, and acknowledged the MDS was coded incorrectly. Another resident, who had diagnoses including speech and language deficits, dysphagia, aphasia, apraxia, dementia, seizures, and heart failure, was discharged to home with home health services. However, the discharge MDS incorrectly indicated the resident was discharged to a hospital setting. The MDS Coordinator admitted to the error, explaining that she had attended the care plan meeting and was aware the resident returned home, but the MDS was not coded accordingly. The Director of Nursing and Administrator both confirmed the importance of accurate MDS coding and attributed the error to human mistake. A third resident with a history of COPD, idiopathic interstitial pneumonia, and dependence on supplemental oxygen was also affected by inaccurate MDS coding. Although the resident's care plan, physician orders, and progress notes documented regular use of supplemental oxygen, the MDS did not indicate oxygen use during the lookback period. The MDS Coordinator and DON both confirmed, after reviewing the records, that the resident was using oxygen intermittently and that the MDS should have reflected this. Interviews with nursing staff further confirmed the resident wore supplemental oxygen continuously at their request.

F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

A facility failed to ensure MDS assessments accurately reflected resident status for several residents. One resident’s admission MDS listed insulin injections even though she received liraglutide, while two other residents’ MDSs omitted antidepressant, opioid, and scheduled pain medication use despite active orders and MAR documentation. Another resident’s quarterly MDS failed to include respiratory failure as an active dx even though the record, orders, and resident interview confirmed the condition and oxygen use.

Inaccurate Resident Assessments
D
F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

Inaccurate resident assessments were identified for multiple residents when MDS coding did not match the clinical record, observations, or staff statements. One resident was coded as having a restraint-related chair device despite no restraints being observed or ordered, another was coded as not receiving antibiotics despite MAR documentation of mupirocin use, and two other residents had missing or incorrect MDS entries for diagnoses, ROM status, and skin/wound conditions based on admission records, physician notes, wound care documentation, and staff interviews.

Inaccurate MDS Coding for Weight Loss and Active Diagnoses
D
F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

Inaccurate MDS coding affected two residents. One resident had significant weight loss documented in the EHR, but the quarterly MDS did not reflect the loss as required. Another resident with lung cancer and metastatic disease had an admission MDS that omitted active cancer diagnoses from section I. The MDS/LPN acknowledged the missing diagnosis, and the DON stated MDS assessments were expected to be coded accurately.

F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

A facility failed to ensure MDS assessments accurately reflected resident status for multiple residents. One resident’s oxygen use was not captured in Section O despite PRN O2 orders and repeated oxygen saturation documentation, another resident’s MDS omitted oxygen use despite progress notes and an O2 order, a third resident’s MDS omitted depression despite a citalopram order, and a fourth resident’s MDS coded no ROM impairment even though PT identified quadriplegia with limitations in all extremities.

Inaccurate MDS Weight Loss Coding
D
F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

A resident’s quarterly MDS incorrectly coded significant weight loss even though his documented weights did not show 5% loss in 1 month or 10% loss in 6 months. The MDS RN said she based the coding on weight fluctuations and medication changes rather than actual loss during the look-back period, and the resident’s care plan continued to reflect significant unplanned weight loss, poor intake, and anxiety.

Inaccurate MDS Coding for Diabetes Medications
D
F0641 F641: Ensure each resident receives an accurate assessment.
Short Summary

Inaccurate MDS coding was found for two residents whose diabetes meds were non-insulin injectables. One resident with ESRD and diabetes had Ozempic ordered, and another resident with CKD and diabetes had Mounjaro ordered, but both MDS assessments incorrectly coded insulin use and hypoglycemic drug class use. The MDS coordinator acknowledged the coding error but did not update the assessments after learning of the inaccuracy.
