ADHD ICD-10 Diagnosis Codes
One of the most common neurodevelopmental disorders is ADHD, or attention-deficit/hyperactivity disorder. Those with this condition usually experience the onset during childhood or adolescence, though patients can have varying types. To diagnose a patient, you’ll have to use the F90 block of ADHD ICD-10 codes.
Get a quick refresher on these codes and learn how Weave’s communication platform can aid you with the process.
Overview of the F90 ADHD code block
When diagnosing ADHD patients, you’ll always use a code starting with F90. For a more specific diagnosis, a decimal and additional number will follow. Every subcode represents the key symptoms someone exhibits to reflect the following types:
- Inattentive ADHD
- Hyperactive-impulsive ADHD
- Combined presentation
The F90 block does have a code for an unspecified type, though this should only be used as a last resort in the absence of adequate documentation.
Types of ADHD and their ICD-10 codes
F90.0 – Predominantly inattentive type
Is your patient easily distracted or has trouble focusing? Their appropriate ADHD ICD-10 code may be F90.0. If someone has attention-deficit/hyperactivity disorder (predominantly inattentive presentation), they struggle with inattention, but hyperactive or impulsive behaviors aren’t as obvious.
F90.1 – Predominantly hyperactive-impulsive type
You could diagnose a child with this type of ADHD when hyperactivity and impulsive behaviors are well documented, including:
- Constant fidgeting
- Excessive talking or interrupting others
- Struggling to wait their turn
- General restlessness
It’s fairly easy to identify this developmental disorder in younger patients, as they exhibit noticeable amounts of energy.
F90.2 – Combined type
What if someone shows equal amounts of inattentive and hyperactive symptoms? The best ADHD ICD-10 code to use is F90.2. Clinicians tend to diagnose most children with this type of ADHD.
F90.8 – Other ADHD
You may find that a patient doesn’t fit the criteria for any of the subtypes mentioned above. Abnormal symptom patterns could occur when behavioral or mental health conditions are at play, such as autism spectrum disorder or bipolar disorder. When someone’s ADHD presentation doesn’t exactly fit another category, you could code it as other ADHD.
F90.9 – ADHD, Unspecified
Maybe a provider has already diagnosed someone before they come to you. If their medical chart doesn’t list any other diagnostic criteria, the associated code would be for an unspecified type of the disorder.
Bear in mind that overusing F90.9 may lead to denied insurance claims or even audits.
When to use each ADHD code
There’s a simple four-step process for finding the right ADHD ICD-10 code:
- Review your patient’s symptoms.
- Match them to the corresponding code.
- Flag the chart if you need further clarification.
- Avoid using F90.9 unless absolutely necessary.
Why accurate ADHD ICD-10 coding matters
Clinical care and continuity
A patient’s ICD-10 code for ADHD dictates the type of treatment they’ll need. For example, inattentive patients could benefit from improving organizational skills, while the hyperactive type may need medications.
Insurance and authorization
Insurers may only cover treatment when there’s a specific code used. Avoid delayed or denied claims by finding the proper code for your patient.
ADHD in practice
When will different ADHD ICD-10 codes apply to your patients? Check out some examples below.
- A 35-year-old adult says they have trouble focusing with no signs of hyperactivity. This may be a classic presentation of F90.0 ADHD.
- Tommy, a six-year-old boy, constantly interrupts and can’t sit still, but he doesn’t have difficulty paying attention to teachers. His appropriate ICD-10 code would be F90.1.
- Suppose a teenager is equally fidgety and distracted in class. You could diagnose them under F90.2, or attention-deficit/hyperactivity disorder, combined type.
- Kyle has ADHD in his chart, but no specific symptoms are listed. He would qualify for the F90.9 code.
