Inaccurate MDS Diagnosis Coding
Summary
The facility failed to ensure an accurate assessment for one resident when it coded schizophrenia on the MDS without current supporting documentation showing the diagnosis was active or directly related to the resident’s current status. Resident #7’s admission MDS documented intact cognition with a BIMS score of 15/15 and listed active diagnoses of generalized anxiety disorder, depression, and agoraphobia with panic disorder, along with antianxiety and antidepressant medications. The record also included a 1990 hospital discharge summary showing schizophrenia, residual type, and schizoid personality disorder, but that document did not show current treatment with quetiapine at that time. Later behavioral health notes documented quetiapine prescribed for major depressive disorder, PTSD, and GAD, and a therapist visit note listed GAD, schizoid personality disorder, and agoraphobia with panic disorder. Facility provider visit notes listed an active problem list but did not include a current diagnosis of schizophrenia or schizoid personality disorder, even though quetiapine remained ordered. The quarterly MDS documented a new diagnosis of schizophrenia and antipsychotic medication use, but it lacked documentation of active delirium, behaviors, hallucinations, or delusions. During interviews, the PMHNP stated she had started quetiapine for panic-type anxiety, agoraphobia, and PTSD, had seen the old 1990 schizophrenia documentation, but had not diagnosed the resident with schizophrenia or schizoid personality disorder and did not consider those diagnoses relevant to the resident’s current condition. The LPN stated she coded schizophrenia on the MDS after receiving the old records and did not verify whether the diagnosis remained current. The DON stated she entered the quetiapine order using the 1990 schizophrenia diagnosis, later confirmed there was no documentation supporting schizophrenia, and identified the MDS entry as a coding error.
