How to Code Cognitive Visits Using E/M (99213–99215)

By Kathy Sager, CPC, CPMA

Where E/M Fits in Cognitive Care

When patients present with cognitive concerns, clinicians often perform several types of work during a visit. This may include medical evaluation, cognitive screening or testing, review of prior records, and discussions with caregivers about safety or functional changes.

For cognitive care activities, most practices are familiar with the neuropsychological testing codes (96136, 96138, 96132). But E/M codes — specifically 99213–99215 — are a billing pathway that can be applied when the requirements for neuropsychological testing codes are not fully met. Cognitive visits frequently qualify for moderate or high E/M levels without providers realizing it, which means reimbursement is either being missed or undercoded.

Depending on the purpose of the visit and the services performed, clinicians may consider billing:

  • Evaluation & Management (E/M) services

  • Neuropsychological testing services

  • Both, if all requirements are independently met

That decision should be based on whether the billing requirements for the service were fully satisfied.


Understanding the Operational Difference

The key distinction between these services lies in the purpose of the work performed.

E/M services focus on the medical evaluation and management of the patient’s condition. Cognitive concerns may be discussed, screened, or reviewed as part of the overall visit while the clinician evaluates symptoms, reviews relevant information, and develops a management plan.

Neuropsychological CPT codes apply when standardized cognitive testing is administered and professionally interpreted as distinct services.

In other words, the question is not whether cognition was discussed — it is whether the requirements for neuropsychological testing were fully met.

How to Code Cognitive Visits Using E/M (99213–99215)

Cognitive visits often drive higher complexity — but they are frequently undercoded.

Under current CPT guidelines, office/outpatient E/M levels (99202–99215) are selected based on:

  • Medical Decision Making (MDM) or

  • Total Time on the Date of Service

Cognition most often impacts MDM, and it can affect all three required elements.


Where Cognition Impacts MDM

MDM is based on three elements:

  1. Problem Complexity

  2. Data Reviewed and Analyzed

  3. Risk of Management

Two of the three must meet or exceed a level.


1. Problem Complexity in Cognitive Care

Low Complexity (Often 99213)

  • Stable MCI

  • Stable dementia

  • No behavioral changes

  • No medication adjustments

Documentation should show stability and monitoring.


Moderate Complexity (Often 99214)

  • Worsening cognition

  • Functional decline (ADLs/IADLs)

  • Behavioral symptoms

  • Medication changes

  • Safety concerns

  • Caregiver strain

Documentation must show progression and management decisions.


High Complexity (Often 99215)

  • Acute delirium

  • Sudden mental status change

  • Severe behavioral disturbance

  • Safety crisis

  • Loss of capacity

  • Threat to bodily function

Document acuity, instability, and urgency.


2. Data: The Most Missed Opportunity

Cognitive visits often involve significant data review — but it must be documented.

Examples That Count Toward MDM:

  • Reviewing outside notes

  • Reviewing labs (TSH, B12, CMP, etc.)

  • Ordering imaging

  • Independent interpretation (if not separately billed)

  • Discussion with another physician

  • Independent historian


Independent Historian (Critical in Dementia Care)

CPT allows this when:

The patient cannot provide reliable history due to cognitive impairment.

Example documentation:

History obtained from the daughter due to the patient's moderate dementia and inability to recall medications.

This counts toward Category 1 data, but only if clearly documented.


Simplified Data Thresholds

  • Low: 2 Category 1 elements

  • Moderate: 3 Category 1 elements

  • High: Category 1 + discussion with external physician


3. Risk of Management

Risk increases when management decisions are made — not just when diagnoses exist.

Moderate Risk (supports 99214)

  • Starting or adjusting prescription medication

  • Capacity evaluation

  • Driving safety counseling

  • Home health initiation

  • Behavioral management planning

⚠ Prescription drug management automatically qualifies as Moderate risk.


High Risk (supports 99215)

  • Decision regarding hospitalization

  • Severe agitation posing danger

  • Acute delirium with instability


Coding Scenarios Made Simple

Scenario 1

Stable dementia

No medication changes

Minimal data

→ 99213


Scenario 2

Dementia progression

Independent historian

Labs reviewed

Medication adjusted

Safety counseling

→ 99214


Scenario 3

Acute delirium

Workup ordered

Discussion with ED physician

Medication management

High safety concern

→ 99215

When Time May Be Better Than MDM

Cognitive visits often involve:

  • Family meetings

  • Capacity discussions

  • Care coordination

  • Extensive counseling

If total time exceeds threshold:

  • 40–54 minutes (Established) → 99215

  • Even if MDM supports only 99214

Time includes same-day:

  • Record review

  • Documentation

  • Communication

  • Care coordination


Documentation: What's Required

A note that simply states "Dementia – stable" does not meet documentation requirements and will not support the code billed.

Correct documentation should reflect the full picture of the visit. For example:

"Patient presents with known dementia. Daughter accompanied and reports increased confusion over the past three weeks and two recent incidents of leaving the stove on. ADLs reviewed — patient now requires assistance with medication management and meal preparation. TSH and B12 reviewed and within normal limits. Assessed driving safety; counseled family on next steps. Medication adjusted. Plan to recheck cognition in 90 days."

This documents problem complexity, data reviewed, an independent historian, and a management decision — supporting 99214.

Required documentation elements:

  • Functional status (ADLs/IADLs)

  • Behavioral assessment

  • Medication reconciliation

  • Caregiver input

  • Safety evaluation

  • Data reviewed and its source

  • Management plan with rationale


Final Takeaway

Cognition is not automatically high level — but it frequently supports moderate or high MDM when properly documented.

The difference between 99213 and 99214 in cognitive care is usually documentation clarity — not the diagnosis itself.
