CDEO key terms

The complete set of clinical documentation for a patient, including notes, orders, test results, and correspondence, that supports the care delivered and the codes billed. It must be accurate, timely, and retrievable.

The principle that a record accurately and completely reflects the encounter as it happened, with no fabricated, copied, or omitted content, and that each entry is attributable to its author.

A brief statement, usually in the patient's or clinician's words, describing the reason for the visit. It frames the encounter and begins the history portion of the note.

A narrative describing the development of the presenting problem, often structured with elements such as location, duration, severity, timing, context, modifying factors, and associated signs and symptoms.

An inventory organized by body system reporting symptoms the patient admits or denies. It is documented separately from the present illness narrative and contributes to the level of history obtained.

Documentation of the patient's prior conditions and treatments, illnesses among blood relatives, and lifestyle or occupational factors relevant to the current complaint and ongoing care.

The complexity of establishing a diagnosis and choosing management, judged by the number and complexity of problems addressed, the data reviewed, and the risk of complications or morbidity.

A ranked list of conditions that could explain the patient's symptoms. Documenting it shows clinical reasoning and can support the complexity of problems addressed during the visit.

A maintained summary of a patient's active and historical conditions, usually placed at the front of the chart. An accurate list helps clinicians and coders identify conditions that were addressed or monitored.

A dated, signed addition to a previously finalized note that clarifies or corrects content without altering the original entry. It should state why the change is needed and never obscure the original text.

Carrying text from an earlier note into a new one without confirming it still applies. Left unedited, it creates cloned documentation that misstates the encounter and damages the record's credibility.

The author's signature, electronic credential, or other approved identifier confirming the entry was reviewed and is accurate. Unsigned or improperly authenticated entries generally cannot support billed services.

The determination that a service, test, or treatment is reasonable and required to diagnose or treat the patient's condition according to accepted standards of care. It underpins both coding and payment.

The ranked complexity category assigned to an evaluation and management visit, such as straightforward, low, moderate, or high, selected by meeting the elements of medical decision making or total time.

The American Medical Association's code set of five-character numeric and alphanumeric codes used to report procedures and professional services on physician and outpatient claims.

The diagnosis code set used on outpatient claims, with codes up to seven characters describing conditions, symptoms, causes, and external factors. Assignment follows official guidelines and coding conventions.

A national code set maintained by CMS for products, supplies, and services not represented in CPT, including drugs, durable medical equipment, and certain professional services.

A short code appended to a procedure code to convey a distinguishing circumstance, such as a different site, a repeated service, or a reduced service, without changing the underlying procedure reported.

CMS edit pairs identifying code combinations generally not reportable together on the same claim. A modifier may be appropriate only when documentation supports a genuinely distinct service.

Reporting components of a single procedure or service as separate codes, raising payment without documentation support. It is a frequent audit finding and a significant compliance risk in outpatient claims.

Assigning a higher-level or more extensive code than the documentation supports. Whether intentional or an error, it produces overpayment that must be corrected through refund or claim adjustment.

A billing arrangement in which a service furnished by auxiliary personnel is reported under the supervising physician's identifier, provided the physician established the course of care and remains immediately available.

A written notice given to a Medicare beneficiary before a service likely to be denied as not medically necessary, shifting potential financial liability to the patient if the service is furnished.

A diagnosis group used in risk adjustment models, each grouping conditions with similar expected cost. Capturing documented, validated HCC conditions supports accurate payment and population health measurement.

A numeric score from a risk adjustment model comparing a member's expected cost with the average. It is calculated from demographic factors and from documented, validated diagnosis codes.

A memory aid for documenting assessment and management of a condition: monitoring signs or symptoms, evaluating test results, assessing the condition, and treating it. At least one element supports coding the condition.

The review step confirming a coded diagnosis is supported by clinical evidence in the record, such as provider documentation, test results, and treatment, not merely a problem list entry or prior claim.

A condition the clinician is considering but has not confirmed, often written as possible, probable, or rule out. Outpatient and risk adjustment coding generally may not report these as confirmed conditions.

Pre-visit review of the record to find care gaps, missing documentation, or conditions needing attention, so the provider can address them during the encounter rather than after the claim is filed.

A standardized set of performance measures used by health plans to evaluate preventive care, chronic condition management, and patient experience, calculated largely from claims and clinical data.

The Merit-based Incentive Payment System, a Medicare quality program scoring eligible clinicians on quality, cost, improvement activities, and promoting interoperability, with scores adjusting future payments.

The percentage of a patient population whose documented conditions are submitted in the current year. A falling rate signals documentation or coding gaps that can lower risk scores and reported quality.

A written or electronic communication asking the treating provider to clarify, add, or confirm documentation so a condition or service can be coded accurately and supported by the record.

A query that steers the provider toward an answer the coder expects, for example by naming a diagnosis the record does not support. Compliant queries present evidence and offer unbiased options.

A summary of chart review results showing error types, error rates, and financial impact, used to prioritize education and to track improvement over successive review cycles.

Focused training delivered to an individual provider or small group based on that group's own documented patterns and audit results, rather than generic coding updates sent to the whole organization.

A respected clinician who partners with the coding and compliance team to promote documentation standards among peers, lending credibility and opening practical channels for two-way feedback.

A comparative reference such as an internal trend, a peer group, or national data used to judge performance on measures like documentation error rate, risk score accuracy, or query response time.

A communication technique in which the educator explains a concept and asks the learner to restate it in their own words, confirming understanding before moving to the next topic.
