Traumatic brain injury (S06.9X9A): Brain injuries can cause attention issues, but they should not be misdiagnosed as ADHD.
Bipolar disorder (F31.9): Manic episodes in bipolar disorder can resemble hyperactivity but are episodic, unlike persistent ADHD symptoms.
What Are the Different Types of ADHD & Their ICD-10 Codes?
This categorization comprises several specific codes, each reflecting a unique manifestation of ADHD symptoms:
These distinct codes facilitate precise documentation and enhance communication among medical professionals. Accurate coding is essential for effective treatment and reimbursement processes.
F90.0 - ADHD, Predominantly Inattentive Type
F90.0 code specifies ADHD, predominantly inattentive type. Patients primarily struggle with inattention rather than hyperactivity.
Common symptoms include:
Difficulty paying attention to details.
Frequent daydreaming.
Forgetfulness and disorganization.
Often goes unnoticed due to the lack of hyperactivity.
Misdiagnosis is common, emphasizing the need for careful assessment.
Accurate coding under F90.0 ensures patients receive targeted interventions to improve attention.
Patients exhibit excessive motor activity and impulsive behaviors.
Common symptoms include:
Constant fidgeting and restlessness.
Difficulty staying seated in appropriate situations.
Excessive talking and interrupting conversations.
Impulsive decision-making without considering consequences.
Often noticeable in structured environments like classrooms or workplaces. Can lead to social difficulties and behavioral challenges due to impulsivity. Accurate use of F90.1 ensures targeted interventions, such as behavioral therapy and self-regulation techniques.
F90.2 - ADHD, Combined Type
F90.2 code represents ADHD, combined type.
Includes symptoms of both inattentiveness and hyperactivity.
The most prevalent ADHD subtype, covering a wide symptom spectrum.
Patients with combined type ADHD face compounded challenges, such as:
Difficulty focusing.
Impulsive actions.
High activity levels.
Proper use of the F90.2 code is essential for comprehensive treatment, addressing all symptom facets.
F90.8 - ADHD, Other Specified Type
F90.8 code refers to ADHD, other specified type.
Used for cases that do not fit standard ADHD subtypes.
Symptoms may present in unique combinations, requiring individualized attention.
Ensures flexibility in diagnosis, capturing non-traditional symptom patterns.
Provides clinicians with the latitude to describe atypical symptomatology.
Correct use of F90.8 allows for tailored interventions to meet specific patient needs.
F90.9 - ADHD, Unspecified Type
F90.9 code is designated for ADHD, unspecified type.
Used when full diagnostic information is unavailable.
Acts as a placeholder until a more detailed assessment is completed.
Appropriate for initial evaluations or when only limited observations are available.
Helps guide immediate management but signals the need for further examination.
Transitioning to a more specific ADHD code improves treatment precision as more data becomes available.
Applying ICD Codes: Real-World Scenarios
Consider the following aspects when applying ADHD ICD codes:
Comprehensively review patient history and clinician notes.
Ensure symptoms align with a particular ADHD subtype.
Select codes reflecting any comorbid conditions.
Utilizing accurate coding under these guidelines helps maintain treatment integrity. Coders play a pivotal role in supporting patient care through meticulous documentation.
Case Study Examples
Consider a child displaying persistent inattentiveness in school settings. After clinical evaluation, they're diagnosed with ADHD, predominantly inattentive type. In this scenario, the appropriate ICD code would be F90.0.
In another example, a teenager exhibits excessive fidgeting and impulsivity. This leads to a diagnosis of ADHD, predominantly hyperactive-impulsive type. Here, F90.1 would be the suitable code. Real-world applications help clarify theoretical concepts by demonstrating practical coding decisions.
Also consider a patient showing symptoms across inattentiveness and hyperactivity. A thorough assessment confirms the combined type ADHD diagnosis. The F90.2 code best represents this case, reflecting the multifaceted symptom profile.
