CodeDescriptionWhen to UseKey Documentation
F81.0Specific reading disorderFor developmental dyslexia with persistent reading difficulties.
  • Standardized test scores below 85
  • Duration of symptoms ≥6 months
  • Exclusion of other causes like sensory impairments
R48.0Dyslexia and alexiaFor acquired dyslexia, typically following a neurological event.
  • Sudden onset post-neurological event
  • Intact prior reading ability

Clinical Decision Support

Always review the patient's clinical documentation thoroughly. When in doubt, choose the more specific code and ensure documentation supports it.

Billable Code

Decision Criteria

clinical Criteria

  • Persistent reading difficulties with standardized test scores below 85.

coding Criteria

  • Do not use for acquired dyslexia.

Applicable To

  • Developmental dyslexia

Excludes

  • Acquired dyslexia (R48.0)
  • Intellectual disabilities (F70-F79)

Clinical Validation Requirements

  • Standardized test scores below 85
  • Duration of symptoms ≥6 months
  • Exclusion of other causes like sensory impairments

Code-Specific Risks

  • Incorrectly using for acquired dyslexia
  • Lack of detailed documentation on specific deficits

Coding Notes

  • Ensure documentation includes specific reading deficits and excludes other causes.

Ancillary Codes

Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Developmental disorder of speech and language, unspecified

F80.9
Use when there are comorbid speech/language deficits.

Differential Codes

Alternative codes to consider when ruling out similar conditions to the primary diagnosis.

Dyslexia and alexia

R48.0
Use R48.0 for acquired dyslexia, typically post-neurological event.

Specific reading disorder

F81.0
Use F81.0 for developmental dyslexia with persistent reading difficulties.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Dyslexia to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code F81.0.

Impact

Clinical: Inadequate information for treatment planning., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials due to insufficient documentation.

Mitigation Strategy

Include specific reading deficits, Use standardized test scores

Impact

Reimbursement: Incorrect coding may lead to denied claims., Compliance: Non-compliance with ICD-10 guidelines., Data Quality: Inaccurate clinical data and reporting.

Mitigation Strategy

Use F81.0 for developmental dyslexia and R48.0 for acquired dyslexia.

Impact

Lack of detailed documentation on reading deficits can trigger audits.

Mitigation Strategy

Ensure all documentation includes specific deficits and standardized test scores.

Documentation errors, coding pitfalls, and audit risks are interconnected aspects of medical coding and billing. Addressing all three areas helps ensure accurate coding, optimal reimbursement, and regulatory compliance.

Frequently Asked Questions

Common questions about ICD-10 coding for Dyslexia, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Dyslexia

Use these documentation templates to ensure complete and accurate documentation for Dyslexia. These templates include all required elements for proper coding and billing.

Child with developmental dyslexia

Specialty: Pediatrics

Required Elements

  • Subjective reports from parents
  • Objective test results
  • Assessment of specific deficits
  • Intervention plan

Example Documentation

**Subjective**: Parent reports difficulty sounding out words since kindergarten. **Objective**: CTOPP-2: Phonological Awareness Composite = 82 (Below Average) **Assessment**: F81.0 – Specific reading disorder with impairments in word reading accuracy and fluency **Plan**: Implement multisensory structured literacy program (45 mins 2x/week)

Examples: Poor vs. Good Documentation

Poor Documentation Example
Child struggles with reading.
Good Documentation Example
Persistent deficits in word reading accuracy (standard score: 75 on WIAT-IV) and reading fluency (below 10th percentile), present for 8 months despite Tier 2 interventions.
Explanation
The good example provides specific deficits, standardized test scores, and duration of symptoms.
