Clinical

A patient classification system that groups hospital inpatient stays into clinically similar categories with similar resource utilization. DRGs are used by CMS to determine Medicare inpatient hospital reimbursement rates. Each DRG has an assigned payment weight used in hospital claims adjudication and financial reporting.

A combination vaccine series documented in EHR immunization records, state immunization registries, and claims systems using CVX and CPT codes. Data engineers reference DTaP records when building HEDIS Combo immunization measure logic, childhood vaccine compliance dashboards, and public health reporting extracts from clinical and claims data sources.

A CMS-mandated financial reconciliation mechanism in Medicare Part D requiring PBMs and plan sponsors to report all manufacturer rebates and price concessions received. Data engineers process DIR data in PBM and health plan systems to adjust net drug costs, true-up pharmacy payments, and support CMS bid and reconciliation reporting workflows.

The patient-facing medication instructions (Signa) encoded in pharmacy prescription records, PBM adjudication transactions, and EHR e-prescribing systems using SIG notation. Data engineers parse and standardize SIG fields during pharmacy data ingestion to support medication adherence analytics, structured label generation, and drug utilization review pipelines.

Pharmacist-provided medication education delivered to patients at the time of facility discharge, documented in pharmacy dispensing systems and EHR platforms to ensure medication adherence, prevent adverse drug events, and satisfy CMS Conditions of Participation and HEDIS transition-of-care quality measures.

The calendar date on which a patient was formally released from an inpatient or outpatient facility, captured in EHR, UB-04 institutional claims, and enrollment systems to calculate length of stay, determine claim billing periods, and trigger post-discharge care management workflows.

A structured clinical and administrative process initiated during inpatient hospitalization to coordinate safe patient transition from acute care to home, skilled nursing, or rehabilitation settings. Documented in EHR systems and used by care management platforms to track post-acute service arrangements, follow-up appointments, and patient education completed prior to discharge.

A clinical directive recorded in an EHR indicating that a patient should not receive cardiopulmonary resuscitation in the event of cardiac or respiratory arrest. Stored as an advance directive flag in patient demographic and care plan tables, governing clinical decision support alerts and care coordination workflows.

A prescriber instruction, coded as DAW in pharmacy and PBM claims systems, indicating that a brand-name drug must be dispensed without generic substitution. Captured in the DAW code field of NCPDP transaction records and impacts reimbursement rates, formulary override logic, and generic substitution reporting in pharmacy adjudication systems.

A medical specialty focused on conditions affecting the ears, nose, throat, and related head and neck structures, commonly abbreviated as ENT or otolaryngology. In EHR and claims systems, ENT encounters are classified under specific ICD and CPT codes used for specialty referral tracking, prior authorization workflows, and provider network management within managed care data platforms.

A cardiac ultrasound procedure captured in EHR and claims systems under CPT codes such as 93306 or 93308, used to assess heart structure and function including ejection fraction, valve integrity, and chamber dimensions. Results are stored as structured diagnostic data in cardiology modules and used for chronic condition management and risk stratification analytics.

A cardiac measurement representing the percentage of blood ejected from the left ventricle per heartbeat, stored as a structured clinical value in EHR and cardiology systems. Normal range is 50–70%; values below 40% indicate heart failure with reduced ejection fraction. Used in chronic disease management, risk stratification models, and HEDIS quality measure reporting.

A diagnostic test recording the electrical activity of the heart, captured in EHR systems under CPT codes such as 93000 or 93010, used to detect arrhythmias, ischemia, myocardial infarction, and other cardiac abnormalities. ECG results are stored as structured waveform data and used in clinical decision support, emergency triage workflows, and cardiology population health analytics.

A neurological diagnostic procedure that records electrical brain activity via scalp electrodes, documented in EHR systems under CPT codes such as 95812 or 95816. Used to evaluate seizure disorders, epilepsy, sleep disturbances, and encephalopathy. EEG results are stored in neurology modules and referenced in chronic condition management and prior authorization workflows within managed care systems.

A measurable ion or mineral (sodium, potassium, chloride, bicarbonate, magnesium, phosphate, calcium) captured in lab result data within EHR and clinical data systems. Electrolyte values are stored in laboratory observation tables, linked to encounters via LOINC codes, and are critical for clinical analytics, risk stratification, and chronic disease management pipelines.

In healthcare data systems, EMC certification status for medical devices is tracked in EHR and biomedical equipment databases to ensure FDA compliance. Device records store EMC ratings to verify safe operation alongside other electronic equipment in clinical environments.

EMG is a diagnostic procedure measuring electrical activity in muscles and nerves, recorded in EHR systems using CPT codes 95860-95872. Results are stored in clinical data repositories and referenced in claims data for neuromuscular disorder diagnosis, physical therapy authorization, and disability assessments.

Computer-based generation and transmission of prescription orders from prescriber systems directly to pharmacy dispensing systems via networks such as Surescripts. Eliminates paper prescriptions, reduces transcription errors, and enables real-time formulary checking and drug interaction alerts within EHR and PBM platforms.

Pre-hospital emergency care and patient transport via ground ambulance or air medical helicopter. EMS encounter data includes CAD timestamps, response intervals, NEMSIS-coded interventions, vital signs, and crew credentials. Integrated into EHR admission records and claims with revenue code 0540.

Clinical specialty focused on acute, unscheduled care delivered in hospital emergency departments. EM encounter data in EHR and claims systems captures triage acuity levels (ESI 1-5), HCPCS E/M codes 99281-99285, door-to-provider times, and disposition outcomes used in quality reporting and CMS reimbursement workflows.
