MDS Coding Errors for Diagnoses, Medication Use, and Tobacco Use
Summary
Ensure each resident receives an accurate assessment was not met when the facility failed to code required information on MDS assessments for three residents. For one resident with COPD and a documented MDRO, the MDS did not indicate the MDRO even though the care plan identified a risk for infection related to a MDRO and the TAR directed staff to use enhanced barrier precautions for a resistant organism such as ESBL. The MDS Coordinator stated she completed MDS assessments using medical records and resident interviews, and confirmed that if a resident had an MDRO, the MDS should be coded to indicate it. The RAI Manual stated that section I disease conditions require a physician-documented diagnosis in the past 60 days and should be coded when they have a direct relationship to the resident's current status, treatments, monitoring, or risk of death during the look-back period. For another resident, the admission MDS coded use of an anticoagulant even though the only medication identified was aspirin 81 mg daily, which is an antiplatelet and not an anticoagulant; no anticoagulant medications were found in the physician orders. The MDS Coordinator said aspirin had been directed to be coded as an anticoagulant by staff from a mock survey, but could not recall when that instruction was given. For a third resident, the admission MDS marked current tobacco use as no even though the resident had a diagnosis of cigarette nicotine dependence, the prior facility's care plan documented active smoking with unsupervised smoking, and a progress note recorded the resident going in and out of the building to smoke. The MDS Coordinator said the smoking status was not well known on admission, while the RAI Manual stated tobacco information may come from the resident or the medical record and that if there are indications of tobacco use, J1300 should be marked yes.

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 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 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.
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.
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 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.
Inaccurate MDS Assessments for Medication Use and Diagnoses
Penalty
Summary
The facility failed to ensure that resident assessments accurately reflected resident status for 4 of 24 residents reviewed. For Resident #54, the admission MDS documented 2 insulin injections in the prior 7 days and identified diabetes mellitus, but the medication record showed she was receiving liraglutide subcutaneously once daily and was not prescribed insulin. The MDS nurse stated liraglutide is a diabetic medication but is not insulin, and the admission MDS should not have noted insulin injections. For Resident #57, the quarterly MDS did not document antidepressant use in Section N or scheduled pain medication in Section J. The resident’s orders included trazodone 150 mg daily, Tylenol 325 mg two tablets twice daily for pain, and Voltaren gel twice daily for left knee pain, and the MAR showed these medications were administered during the lookback periods. The care plan also identified a need for antidepressant medication and noted a potential for uncontrolled pain. For Resident #81, the quarterly MDS did not list respiratory failure as an active diagnosis even though the resident’s record included acute and chronic respiratory failure with hypoxia and an active order for acetazolamide for respiratory failure. The resident was observed with oxygen equipment in his room and stated he used oxygen at night because of his respiratory failure. For Resident #91, the MDS did not document opioid use in Section N or scheduled pain medication in Section J, despite an active order for tramadol 50 mg twice daily for chronic pain and MAR documentation showing it was administered during the lookback period. The MDS nurse stated she was responsible for ensuring MDS accuracy and that inaccurate information could mean care was not delivered correctly or something could be missed.
Inaccurate Resident Assessments
Penalty
Summary
Resident assessments were not completed accurately to reflect resident status for 4 of 9 residents reviewed. For one resident, the quarterly MDS dated 5/8/2026 indicated under Section P that a chair prevented rising and was used less than daily, yet observations on 6/8/2026 and 6/9/2026 showed the resident sitting in a wheelchair with no restraints observed, and the resident stated she did not use any restraints. The physician orders also did not document any restraint use, and staff, including the LPN, MDS Coordinator, and DON, stated that no restraints were used in the facility. For another resident, the quarterly MDS dated 5/23/2026 marked Section N Medications as no antibiotics, but the physician order and MAR showed Mupirocin External Ointment 2% was administered from 5/16/2026 through 5/22/2026 for a fungal rash on the left pointer and middle fingers. The MDS Coordinator stated that the assessment should have reflected antibiotic use and said it would be corrected. The DON stated the facility follows the RAI. For a third resident, the admission record listed a left humerus fracture, ventral hernia, and schizophrenia, but the MDS dated [DATE] coded Section GG as no impairment of upper or lower extremity, omitted schizophrenia from Section I, and marked Section M skin conditions as none. Observation showed the resident wearing a black sling on the left arm, and the resident stated she had a hernia surgery in 2010 and had been dealing with the surgical site since then. The wound care nurse described a large weeping abdominal hernia being treated with dressings, and the MDS Coordinator acknowledged the coding was incorrect. For a fourth resident, the admission record and physician documentation showed a history of TIA and cerebral infarction without residual, but the MDS Section I did not include those diagnoses. The MDS Coordinator stated the resident had a TIA and stroke history and that it needed to be added to Section I.
Inaccurate MDS Coding for Weight Loss and Active Diagnoses
Penalty
Summary
The facility failed to ensure the minimum data set (MDS) accurately reflected the status of 2 of 22 sampled residents reviewed for assessment accuracy. For Resident 112, the electronic health record showed admission with diagnoses including diabetes, weakness, and hemiplegia/hemiparesis affecting the right side. The resident was able to make needs known. The record also showed weights of 184 pounds on 03/14/2026, 150 pounds on 04/11/2026, and 146 pounds on 04/19/2026, but the 05/06/2026 quarterly MDS marked the item for loss of 5 percent or more in the last month or loss of 10 percent or more in the last 6 months as NO or UNKNOWN. For Resident 21, the electronic health record showed admission with diagnoses including malignant neoplasm of the lung and secondary malignant neoplasm of the brain and adrenal gland. The admission MDS showed the resident was able to communicate needs, but the cancer diagnoses were not coded in section I for active diagnoses. During interviews, the MDS/LPN stated the cancer diagnosis was missing from the MDS and should have been coded, and the DON stated the expectation was that MDS assessments were coded accurately and that active diagnoses should be on the MDS.
Inaccurate MDS Assessments for Oxygen Use, Depression, and Range of Motion
Penalty
Summary
The facility failed to ensure resident assessments were completed accurately to reflect resident status for 4 of 13 residents reviewed. Resident #3’s Medicare 5-day MDS dated 5/7/2026 did not document oxygen use in Section O, even though the physician order dated 4/28/2026 directed oxygen 2L via nasal cannula PRN and the resident’s oxygen saturation records showed repeated oxygen use during the look-back period. The MDS Coordinator stated the assessment needed to be corrected because the resident did use oxygen during the look-back period. Resident #15’s Medicare 5-day MDS dated 4/2/2026 also did not document oxygen use in Section O, despite a physician order for O2 at 3L via nasal cannula PRN for respiratory distress and progress notes documenting oxygen use via nasal cannula at 2L and 3L. Resident #56’s modification of admission Medicare 5-day MDS dated 4/9/2026 did not document depression in Section I, although the resident had an order for citalopram 20 mg daily related to depression. Resident #19’s MDS dated 4/15/2026 coded no impairment in range of motion for both upper and lower extremities in Section GG, while the resident was observed in PT receiving services and was identified by the PT as a quadriplegic with spinal cord injury and limitations in range of motion in all extremities.
Inaccurate MDS Weight Loss Coding
Penalty
Summary
The facility failed to ensure Resident #7’s assessment accurately reflected his status when the quarterly MDS completed on 03/23/26 coded Section K0300 as significant weight loss in the last month or last 6 months. Resident #7 was a 63-year-old male admitted with diagnoses including unspecified protein-calorie malnutrition and dehydration, and his BIMS score was 9, indicating moderately impaired cognition. The MDS also supported a care plan focus area for significant unplanned/unexpected weight loss, poor food intake, and anxiety issues that had been initiated on 10/16/25. Record review of Resident #7’s weights showed no 5% weight loss in 1 month or 10% weight loss in 6 months relative to the ARD date of the quarterly MDS. His documented weights were 119 pounds on 03/22/26, 117.2 pounds on 02/20/26, and 120 pounds on 09/24/25. During interview, the MDS RN stated she coded significant weight loss because the resident’s weight had fluctuated and medication changes seemed to have affected his weight, rather than because of actual weight loss during the look-back period. The facility policy stated the purpose of the MDS is to ensure each resident receives an accurate assessment, and the RAI manual stated that only the two snapshot weights closest to 30 and 180 days are considered for K0300.
Inaccurate MDS Coding for Diabetes Medications
Penalty
Summary
The facility failed to ensure accurate MDS coding for dialysis-related medications for two residents. Resident 4 had diagnoses including type 2 diabetes mellitus without complications, end stage renal disease, and dependence on renal dialysis. His EMR showed an order for Ozempic (semaglutide) 0.25 mg subcutaneously once weekly for diabetes, but his annual MDS coded section N0350 as insulin injections in the last seven days as yes and section N0415J hypoglycemic (including insulin) as yes. Resident 59 had diagnoses of chronic kidney disease and type 2 diabetes mellitus without complications. Her EMR showed an order for Mounjaro (tirzepatide) 2.5 mg subcutaneously once weekly for diabetes, but her quarterly MDS coded section N0350 as one insulin injection in the last seven days and section N0415J hypoglycemic (including insulin) as yes. The MDS coordinator stated she knew Ozempic and Mounjaro were coded inaccurately as insulin and learned of the inaccuracy on 4/24/26, but did not update the MDS assessments for residents 4 and 59.
