Private-Pay Adult ADHD Care With Clear Pricing
ADHD Philadelphia is a private-pay practice.
We do not accept or bill insurance directly.
You will know the cost of your evaluation and follow-up care before scheduling.
Superbills may be available for patients who wish to seek possible out-of-network reimbursement from their insurance company.
Reimbursement depends on your individual insurance plan and is not guaranteed by ADHD Philadelphia.
If you plan to seek reimbursement, contact your insurance company directly to ask about your out-of-network mental-health benefits and superbill requirements.
Two Adult ADHD Evaluation Pathways
Adults seek ADHD evaluations for different reasons.
Some want an evaluation and plan to establish ongoing ADHD treatment with ADHD Philadelphia when clinically appropriate.
Others primarily want a comprehensive diagnostic evaluation and expect their ongoing treatment to occur elsewhere.
ADHD Philadelphia offers two clear pathways.
Pathway 1 — ADHD Evaluation + Ongoing Care
$300 Total Initial Evaluation
This pathway is intended for adults who want an ADHD evaluation and plan to establish ongoing treatment with ADHD Philadelphia when continued care is clinically appropriate.
Step 1 — Initial ADHD Consultation: $150
The consultation may review:
Current ADHD symptoms
Childhood and developmental history
Functional impairment
Work functioning
Academic history
Executive-function difficulties
Organization
Time management
Task initiation
Working memory
Follow-through
Relationships
Daily responsibilities
Sleep
Medical history
Psychiatric history
Current medications
Previous treatment
Substance-use considerations
Possible alternative explanations
Possible co-occurring conditions
The goal is to understand the broader developmental, clinical, and functional picture.
Step 2 — ADHD Testing & Results Appointment: $150
Testing may include standardized ADHD questionnaires and computerized cognitive assessment when clinically appropriate.
Testing provides useful clinical information, but computerized testing does not diagnose ADHD by itself.
Findings are interpreted together with:
Developmental history
Current symptoms
Functional impairment
Clinical interview findings
Standardized ADHD measures
Medical history
Psychiatric history
Differential diagnosis
Other relevant clinical information
Total Initial Evaluation: $300
$150 Initial ADHD Consultation
$150 ADHD Testing & Results Appointment
Ongoing ADHD Care
Ongoing ADHD treatment and medication-management appointments are:
$150 per appointment
START ADHD EVALUATION + ONGOING CARE
Pathway 2 — ADHD Testing & Evaluation Only
$500 Comprehensive Standalone Diagnostic Evaluation
This pathway is intended for adults who want a comprehensive ADHD diagnostic evaluation but do not plan to establish ongoing ADHD treatment with ADHD Philadelphia at the time of the evaluation.
The evaluation may include:
Detailed diagnostic interview
Current ADHD symptom assessment
Childhood and developmental history
Functional-impairment assessment
Work or academic functioning
Executive-function assessment
Medical history
Psychiatric history
Sleep
Medication review
Substance-use considerations
Standardized ADHD questionnaires
ADHD testing
Differential diagnosis
Relevant records when necessary
Collateral information when clinically appropriate
Other information needed to reach an appropriate diagnostic conclusion
Total Standalone Evaluation: $500
Diagnostic documentation is generally completed within 7 days after all required appointments, testing, questionnaires, records, and requested information have been completed and received.
The seven-day period does not necessarily begin after the first appointment.

Common Signs of Adult ADHD
Adult ADHD does not always look like obvious hyperactivity.
Many adults seek evaluation because of long-standing difficulties such as:
Chronic procrastination
Difficulty starting important tasks
Difficulty sustaining attention
Forgetfulness
Losing track of responsibilities
Poor time awareness
Frequently underestimating how long things will take
Disorganization
Difficulty prioritizing
Starting projects without finishing them
Trouble following through
Restlessness
Impulsive decisions
Inconsistent productivity
Feeling mentally overwhelmed
Difficulty maintaining routines
Depending on urgency to become productive
These experiences do not automatically mean ADHD is present.
Similar difficulties can occur with anxiety, depression, chronic stress, burnout, trauma-related conditions, sleep problems, substance use, medication effects, medical conditions, and other psychiatric or neurodevelopmental conditions.
That is why adult ADHD diagnosis should consider the complete clinical picture.

Comprehensive Adult ADHD Testing & Evaluation
There is no single questionnaire, online quiz, or computerized test that independently establishes an adult ADHD diagnosis.
A comprehensive evaluation may consider:
Current symptoms
Childhood and developmental history
Functional impairment
Symptoms across relevant areas of life
Academic history
Professional functioning
Executive-function difficulties
Medical history
Psychiatric history
Sleep
Current medications
Substance-use considerations
Differential diagnosis
Possible co-occurring conditions
Standardized ADHD measures
Computerized testing when clinically appropriate
Testing contributes information to the evaluation.
It does not replace clinical assessment.

Executive Function and Adult ADHD
Many adults seeking an ADHD evaluation do not initially say:
“I cannot pay attention.”
Instead, they may say:
“I know exactly what I need to do, but I cannot get started.”
“I lose track of time.”
“I make plans but cannot follow them consistently.”
“I forget what I was doing after I get interrupted.”
“I only become productive when the deadline becomes urgent.”
These difficulties may involve executive functions such as:
Working memory
Task initiation
Time management
Organization
Planning
Prioritization
Sustained attention
Response inhibition
Goal-directed persistence
Self-monitoring
Cognitive flexibility
Emotional regulation
ADHD Philadelphia has developed an extensive patient education center covering these individual skills.
Explore the Executive Function in Adults With ADHD Resource Center.
Adult ADHD Care for Professionals
Success Does Not Rule Out ADHD
ADHD can be difficult to recognize in successful professionals.
A person may be performing well while privately struggling with:
Chronic procrastination
Missed or nearly missed deadlines
Documentation backlog
Email overload
Difficulty beginning complex projects
Poor time awareness
Difficulty prioritizing competing demands
Working late to compensate
Weekend catch-up
Mental exhaustion
Inconsistent productivity
Difficulty switching between responsibilities
Some adults compensate through:
Intelligence
Education
Strong work ethic
Perfectionism
Anxiety
Long hours
Deadline pressure
Elaborate organizational systems
Administrative support
Professional success does not rule out ADHD.
The more useful question may be:
How much effort, stress, time, and compensation does it take to maintain that success?
Explore Adult ADHD Care for Professionals in Pennsylvania & Delaware.
Adult ADHD Care That Recognizes the Whole Person
Adult ADHD does not have one appearance, racial background, cultural background, gender identity, sexual orientation, profession, family structure, or life story.
Race, culture, gender identity, sexual orientation, family expectations, workplace environments, discrimination, previous healthcare experiences, and other parts of life may affect how symptoms are recognized or discussed.
These factors should not automatically be treated as explanations for ADHD symptoms.
They also should not be ignored when they are clinically relevant.
Black & BIPOC Adults
ADHD Philadelphia provides individualized adult ADHD care for adults from diverse racial, ethnic, and cultural backgrounds.
Explore Adult ADHD Care for Black & BIPOC Adults in Pennsylvania & Delaware.
LGBTQ+ Adults
ADHD Philadelphia provides respectful adult ADHD care for LGBTQ+, transgender, nonbinary, gender-diverse, questioning, and other adults.
Sexual orientation and gender identity are not ADHD diagnostic criteria and should not automatically be treated as explanations for attention or executive-function difficulties.
Explore LGBTQ+ Affirming Adult ADHD Care in Pennsylvania & Delaware.
Adult ADHD Treatment After Diagnosis
When ADHD is diagnosed and treatment is clinically appropriate, recommendations are individualized.
Treatment planning may consider:
Most impairing symptoms
Functional difficulties
Medical history
Psychiatric history
Current medications
Previous treatment
Work demands
Educational demands
Family responsibilities
Executive-function needs
Treatment preferences
Potential risks
Personal goals
