The electronic health record (EHR) has many benefits:

  • Improved patient care;
  • Improved care coordination;
  • Improved diagnostics and patient outcomes;
  • Increased patient participation; and
  • Increased practice efficiencies and cost savings.1

EHRs also introduce risks, however. Heightened concern about EHR misuse and vulnerability elevates the level of scrutiny placed on provider documentation as it relates to billing and coding. Without clear guidelines from the Centers for Medicare and Medicaid Services (CMS) or other payers, the potential for unintentional misapplication exists. Auditor misinterpretation is also possible. Providers should utilize simple defensive documentation principles to support their services and minimize their risks.

Reason for Encounter

Under section 1862 (a)(1)(A) of the Social Security Act, the Medicare Program may only pay for items and services that are “reasonable and necessary for the diagnosis or treatment of illness or injury or to improve the functioning of a malformed body member,” unless there is another statutory authorization for payment (e.g. colorectal cancer screening).2

A payer can determine if a service is “reasonable and necessary” based on the service indication. The reason for the patient encounter, otherwise known as the chief complaint, must be evident. This can be a symptom, problem, condition, diagnosis, physician-recommended return, or another factor that necessitates the encounter.1 It cannot be inferred and must be clearly stated in the documentation. Without it, a payer may question the medical necessity of the service, especially if it involves hospital-based services in the course of which multiple specialists will see the patient on any given date. Payers are likely to deny services that cannot be easily differentiated (e.g. “no c/o”). Furthermore, payers can deny concurrent care services for the following reasons:3

  • Services exceed normal frequency or duration for a given condition without documented circumstances requiring additional care; or
  • Services by one physician duplicate/overlap those of the other provider without any recognizable distinction.

Providers should be specific in identifying the encounter reason, as in the following examples: “Patient seen for shortness of breath” or “Patient with COPD, feeling improved with 3L O2 NC.”

Assessment and Plan

Accurately representing patient complexity for every visit throughout the hospitalization presents its challenges. Although the problem list may not dramatically change day to day, providers must formulate an assessment of the patient’s condition with a corresponding plan of care for each encounter. Documenting problems without a corresponding plan of care does not substantiate physician participation in the management of that problem. Providing a brief, generalized comment (e.g. “DM, CKD, CHF: Continue current treatment plan”) minimizes the complexity and effort put forth in the encounter and could result in auditor downgrading upon documentation review.

Developing shortcuts might falsely minimize the provider’s documentation burden. An electronic documentation system might make it possible to copy previous progress notes into the current encounter to save time; however, the previously entered information could include elements that do not require reassessment during a subsequent encounter or contain information about conditions that are being managed concurrently by another specialist (e.g. CKD being managed by the nephrologist). Leaving the copied information unmodified may not accurately reflect the patient’s current condition or the care provided by the hospitalist during the current encounter. Information that is pulled forward or copied and pasted from a previous entry should be modified to demonstrate updated content and nonoverlapping care relevant to that date.

According to the Office of Inspector General (OIG), “inappropriate copy-pasting could facilitate attempts to inflate claims and duplicate or create fraudulent claims.”4

An equally problematic EHR function involves “overdocumentation,” the practice of inserting false or irrelevant documentation to create the appearance of support for billing higher level services.4 EHR technology has the ability to auto-populate fields using templates built into the system or generate extensive documentation on the basis of a single click. The OIG cautions providers to use these features carefully, because they can produce information suggesting the practitioner performed more comprehensive services than were actually rendered.4

An example is the inclusion of the same lab results more than once. Although clinicians include this information as a reference to avoid having to “find it somewhere in the chart” when it is needed—as a basis for comparison, for example—auditors mistake this as an attempt to gain credit for the daily review of the same “old” information. Including only relevant data will mitigate this concern.

Authorship

Dates and signatures are essential to each encounter. Medicare requires services provided/ordered to be authenticated by the author.5 A reviewer must be able to identify each individual who performs, documents, and bills for a service on a given date. Progress notes that fail to identify the service date or service provider will likely result in denial.

Additionally, a service is questioned when two different sets of handwriting appear on a note, yet only one signature is provided. Since the reviewer cannot confirm the credentials of the unidentified individual and cannot be sure which portion belongs to the identified individual, the entire note is disregarded.

Notes that contain an illegible signature are equally problematic. If the legibility of the signature prevents the reviewer from correctly identifying the rendering provider, the service may be denied.

CMS has instructed Medicare contractors to request a signed provider attestation before issuing a denial.5 The provider should print his/her name beside the signature or include a separate signature sheet with the requested documentation to assist the reviewer in provider identification. Stamped signatures are not acceptable under any circumstance. Medicare accepts only handwritten or electronic signatures.5

CMS’ General Principles of Medical Record Documentation6

The principles of documentation listed below are applicable to all types of medical and surgical services in all settings. For evaluation and management (E/M) services, the nature and amount of physician work and documentation varies by type of service, place of service, and patient status. The general principles listed below may be modified to account for these variable circumstances in providing E/M services.

1. The medical record should be complete and legible.


2. The documentation of each patient encounter should include:

    • reason for the encounter and relevant history, physical examination findings, and prior diagnostic test results;
    • assessment, clinical impression, or diagnosis;
    • plan for care; and
    • date and legible identity of the observer.

3. If not documented, the rationale for ordering diagnostic and other ancillary services should be easily inferred.


4. Past and present diagnoses should be accessible to the treating and/or consulting physician.


5. Appropriate health risk factors should be identified.


6. The patient’s progress, response to and changes in treatment, and revision of diagnosis should be documented.


7. The CPT and ICD-9-CM codes reported on the health insurance claim form or billing statement should be supported by the documentation in the medical record.
