Consultation Note Template: The 3 R’s, LOINC 11488-4, and CMS vs CPT Coding Rules

Non-clinical documentation notice: This reference outlines electronic health record (EHR) consultation note structures, HL7 C-CDA interoperability standards, and federal/commercial Evaluation and Management (E/M) coding rules for clinical informatics and health services research. It does not provide clinical diagnostic or medical treatment advice.

A consultation note template structures the medical-record documentation generated when a specialist physician or qualified healthcare professional evaluates a patient at the request of another clinician to provide diagnostic or management recommendations for a specific clinical problem. In academic medical centers, multi-specialty clinics, and health services research cohorts, distinguishing a formal consultation from a transfer of care (referral) is essential for both patient-safety coordination and compliance with Evaluation and Management (E/M) audit standards across clinical documentation systems.

What are the 3 defining elements of a clinical consultation (request, opinion/recommendations, written report back to referring clinician)?

Under American Medical Association (AMA) Current Procedural Terminology (CPT) Evaluation and Management guidelines (read 2026-11-10 at https://www.ama-assn.org/system/files/2023-e-m-descriptors-guidelines.pdf) and commercial payer audit standards, a clinical encounter qualifies as a consultation—rather than a standard new or established patient E/M transfer of care—only when the medical record documents all three components of the “Three R’s”:

1. Request (R1): An explicit request from an appropriate requesting physician or qualified healthcare professional (QHP) asking the consultant for an opinion or advice regarding the evaluation or management of a specific clinical problem. The consultation note must name the requesting clinician and state the specific clinical question to be answered.
2. Render Opinion / Evaluation (R2): The consultant’s history, examination, diagnostic review, and clinical synthesis rendering specific diagnostic and/or therapeutic recommendations tailored to the requesting clinician’s question.
3. Report Back (R3): A written report of the consultant’s findings, opinion, and recommendations communicated back to the requesting practitioner. In a shared hospital or integrated health-system EHR, documenting the consultation note in the shared medical record satisfies the written report requirement provided the note explicitly identifies the requesting clinician and addresses their clinical question; in separate outpatient EHRs, proof of transmission (direct secure message, fax log, or routed letter) to the requesting clinician is required.

If the original practitioner transfers complete, ongoing management of a condition to the specialist prior to the visit (for example, “Referred to Cardiology to assume permanent management of atrial fibrillation” rather than requesting consultative advice), the encounter is a transfer of care, not a consultation.

Why did CMS eliminate CPT 99242–99255 consultation codes in 2010 in favor of initial inpatient/outpatient E/M codes while commercial payers retained them?

Under CMS Change Request CR 6740 (Medicare Claims Processing Manual, Chapter 12, § 30.6.10, effective January 1, 2010; read 2026-11-10 at https://www.cms.gov/Regulations-and-Guidance/Guidance/Transmittals/downloads/R1875CP.pdf), the Centers for Medicare & Medicaid Services ceased recognizing CPT office/outpatient consultation codes (99241–99245) and inpatient/observation consultation codes (99251–99255) for Medicare Part B fee-for-service payment. Following Office of Inspector General (OIG) audits showing widespread ambiguity between consultations and transfers of care, CMS standardized Medicare billing so that consulting specialists bill standard E/M codes instead.

However, the AMA CPT Editorial Panel retained the consultation code families—updating them in the 2023 E/M overhaul by deleting the lowest-level codes (`99241` and `99251`) and aligning selection strictly with Medical Decision Making (MDM) or Total Time on the date of the encounter—because many commercial insurers, workers’ compensation programs, and state Medicaid agencies continue to recognize and reimburse `CPT 99242–99255`. Consequently, hospital clinical documentation improvement (CDI) and clinical documentation software platforms use payer-specific crosswalks:

Clinical Setting & MDM / Time Level	Commercial Payers Recognizing CPT Consult Codes (2023+ AMA CPT Rules)	Medicare Part B Fee-for-Service Crosswalk (Per CMS CR 6740 & 2023 E/M Rules)
Outpatient / Office Consultation (Straightforward, Low, Moderate, or High MDM; or 20 / 30 / 40 / 55+ min total time)	CPT 99242–99245 (Requires documented Request, Render, Report back)	CPT 99202–99205 (New Patient) or CPT 99212–99215 (Established Patient within specialty group in past 3 years)
Inpatient or Observation Consultation (Straightforward, Low, Moderate, or High MDM; or 35 / 45 / 60 / 80+ min total time)	CPT 99252–99255 (Limit 1 inpatient consultation per admission per consultant/specialty)	CPT 99221–99223 (Initial Hospital Inpatient or Observation Care — Admitting physician appends Modifier -AI to identify Principal Physician of Record; consultants bill `99221–99223` without `-AI`)

What is a complete worked template for an inpatient and outpatient specialist Consultation Note (LOINC 11488-4)?

In the HL7 Consolidated Clinical Document Architecture (C-CDA R2.1), specialist consultations are standardized under the Consultation Note Document Template (OID 2.16.840.1.113883.10.20.22.1.4), mapped to LOINC 11488-4 (Consult note, read 2026-11-10 at https://loinc.org/11488-4/). Clinicians using ambient tools such as Twofold AI medical scribe for clinicians or structured SOAP note assessment macros should ensure the opening and closing lines explicitly satisfy the Three R’s and `LOINC 11488-4` section mappings.

Worked Inpatient Specialist Consultation Note Template (`LOINC 11488-4`)

Infectious Diseases will follow the patient daily during hospitalization.” (Total encounter time on date of service: 62 minutes; High MDM).

Frequently Asked Questions

What are the 3 defining elements of a clinical consultation (request, opinion/recommendations, written report back to referring clinician)?

A valid consultation requires the “Three R’s”: (1) a documented Request from another physician or qualified healthcare professional for advice on a specific clinical problem, (2) Rendering an evaluation and clinical opinion/recommendations, and (3) sending a written Report of findings and recommendations back to the requesting practitioner.

Why did CMS eliminate CPT 99242–99255 consultation codes in 2010 in favor of initial inpatient/outpatient E/M codes while commercial payers retained them?

Effective January 1, 2010 (`CR 6740`), CMS stopped recognizing CPT consultation codes for Medicare Part B after OIG audits found widespread ambiguity between consultations and transfers of care. Under Medicare, consultants bill initial hospital care (`CPT 99221–99223` without the admitting physician’s `-AI` modifier) or office E/M (`99202–99215`), whereas commercial payers continue to recognize `CPT 99242–99245` and `99252–99255`.

What is a complete worked template for an inpatient and outpatient specialist Consultation Note (LOINC 11488-4)?

A compliant HL7 C-CDA LOINC 11488-4 Consultation Note names the requesting clinician and clinical question (`42349-1`), documents the HPI (`10164-2`), medications/allergies, physical exam (`29545-1`), independent diagnostic review (`30954-2`), numbered consultative recommendations (`51847-2`), and confirmation that the written report was communicated back to the requesting clinician.
