- IMO IDs provide a persistent foundation for clinical concepts, even as healthcare standards evolve.
- IMO IDs connect clinician-friendly language to standardized code systems while preserving clinical intent.
- IMO Health’s terminology helps maintain consistent, usable healthcare data despite evolving clinical language and documentation practices.
Maintaining clinical terminology at scale is incredibly difficult. Medical knowledge evolves constantly, new diseases emerge, clinical language becomes more precise, and standardized code systems are continuously updated. Behind the scenes, organizations across the healthcare ecosystem are tasked with keeping all of that data connected, consistent, and clinically meaningful over time.
At IMO Health, one of the foundational elements that help make that possible is IMO IDs.
While most clinicians and healthcare organizations may never interact directly with an IMO ID, it plays a critical role in modern clinical terminology and the entire healthcare ecosystem. It helps preserve clinical meaning and intent, maintain continuity across evolving code systems, and enable more accurate documentation, analytics, and interoperability.
“I like to call an IMO ID the permanent address associated with an IMO descriptor,” says Amol Bhalla, MD, M.SCI, MHSA, MBA, Chief Clinical Informaticist at IMO Health. “No matter what happens in time, that permanent address is always associated with that house.”
What is an IMO ID?
At its simplest, an IMO ID is a persistent identifier tied to a clinical concept.
The identifier itself is numerical, but it is associated with a descriptor – the clinical term or phrase representing what is being documented, captured, or exchanged within healthcare workflows. Together, the IMO ID and descriptor create a stable foundation for clinical terminology.
I like to call an IMO ID the permanent address associated with an IMO descriptor. No matter what happens in time, that permanent address is always associated with that house.”
Bhalla compares it to a permanent address attached to a house. Renovations may happen over time. New rooms may be added. The surrounding neighborhood may change. But the address itself remains constant.
The same principle applies to clinical terminology. Standard code systems like ICD-10-CM, SNOMED CT®, RxNorm®, and others continuously evolve. New concepts are introduced. Existing concepts may become more specific. Some codes may even be retired or replaced.
The IMO ID, however, persists.
“No matter what happens in the clinical world, the IMO ID and descriptor will never change, so you can always count on it,” Bhalla explains.
Why is clinical terminology so difficult to maintain?
Healthcare language is constantly evolving.
As medicine advances, clinicians need more precise ways to describe diseases, procedures, medications, and patient conditions. New discoveries and emerging conditions continuously reshape how healthcare organizations document and structure information.
Breast cancer provides a useful example.
Years ago, SNOMED CT may have represented breast cancer with a broad, generalized concept. Today, there are hundreds of ways to describe different forms and subtypes of breast cancer as medical understanding has advanced. This evolution is important for patient care and precision medicine, but it also creates maintenance challenges for healthcare organizations attempting to manage longitudinal data over time. As terminology changes, organizations still need confidence that historical data will remain connected and clinically meaningful.
That continuity is one of the core strengths of the IMO ID. Because the identifier persists even as code systems evolve, organizations can more effectively support retrospective studies, cohort identification, analytics, and longitudinal patient data analysis without losing the original clinical intent behind the documentation.
How is an IMO ID different from a standard medical code system?
Standardized code systems each serve important, but different, purposes within healthcare.
ICD-10-CM supports billing and reporting workflows. SNOMED CT focuses on clinical terms and interoperability. LOINC® supports laboratory observations. RxNorm standardizes medication naming conventions.
“Every code system has a scope and intent,” Bhalla says.
The challenge is that no single code system fully captures the complexity of how clinical concepts are documented, exchanged, and used across the healthcare ecosystem.
That is where IMO Health’s clinical terminology layer helps bridge the gap.
IMO IDs connect clinician-friendly language to standardized coding systems while preserving the underlying clinical concept. This allows organizations across the healthcare ecosystem to maintain flexibility and specificity while supporting downstream workflows such as reimbursement, interoperability, analytics, reporting, research, and AI applications.
As standards evolve, mappings behind the scenes can be updated and refined without disrupting the persistent clinical concept represented by the IMO ID.
How do IMO IDs support clinical terminology?
One of the biggest challenges in clinical terminology is variability in language.
Clinical language often includes abbreviations, synonyms, acronyms, shorthand, colloquial expressions, and misspellings across documentation, workflows, and healthcare systems. Different specialties may also describe the same condition in different ways. Behind the scenes, IMO Health terminology helps normalize that complexity.
“Behind the scenes is a bag of words that help define that concept,” Bhalla explains.
For example, a clinician searching for diabetes may use abbreviations, alternate terminology, or incomplete phrasing. IMO terminology supports these variations while connecting them back to the same underlying IMO ID and clinical concept. This helps improve usability for clinicians while strengthening consistency across healthcare data.
Why does the IMO ID matter?
Although invisible to most end users, IMO IDs play a critical role in helping organizations across the healthcare ecosystem maintain meaningful, usable, and consistent clinical data over time.
As clinical terminology grows more complex – and healthcare increasingly relies on analytics, interoperability, and AI-driven technologies – preserving clinical intent becomes even more important. The IMO ID helps make that possible by providing a stable foundation beneath evolving terminology and code systems.
And in a healthcare environment defined by constant change, persistence matters.
