CodeDescriptionWhen to UseKey Documentation
G47.33Obstructive sleep apnea (adult) (pediatric)Use for confirmed cases of obstructive sleep apnea with appropriate sleep study documentation.
  • Apnea-hypopnea index (AHI) ≥5
  • Documentation of obstruction (e.g., retrognathia)
F51.01Primary insomniaUse for chronic insomnia not linked to other medical or psychiatric conditions.
  • Documentation of insomnia lasting ≥3 months
  • Evidence of daytime impairment

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

  • AHI ≥5 with documented obstruction

documentation Criteria

  • Sleep study results within the last 12 months

Applicable To

  • Adult obstructive sleep apnea
  • Pediatric obstructive sleep apnea

Excludes

Clinical Validation Requirements

  • Apnea-hypopnea index (AHI) ≥5
  • Documentation of obstruction (e.g., retrognathia)

Code-Specific Risks

  • Incorrect use without sleep study confirmation
  • Failure to document anatomical contributors

Coding Notes

  • Ensure sleep study results are documented within the past 12 months.

Ancillary Codes

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

Obesity, unspecified

E66.9
Use when obesity is a contributing factor to sleep apnea.

Sleep deprivation

Z72.820
Use when sleep deprivation is a contributing factor.

Differential Codes

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

Sleep apnea, unspecified

G47.30
Use when sleep apnea is suspected but not yet confirmed by a sleep study.

Adjustment insomnia

F51.02
Use when insomnia is due to a specific stressor and is temporary.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Sleep Disorder to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G47.33.

Impact

Clinical: May lead to misdiagnosis or inappropriate treatment., Regulatory: Non-compliance with coding standards., Financial: Potential for denied claims.

Mitigation Strategy

Always specify the duration of insomnia in months., Document any daytime impairment.

Impact

Reimbursement: May lead to lower reimbursement rates., Compliance: Increases risk of audits and denials., Data Quality: Decreases accuracy of health records.

Mitigation Strategy

Always confirm diagnosis with appropriate tests and document specifics.

Impact

Coding OSA without recent sleep study documentation increases audit risk.

Mitigation Strategy

Ensure sleep study results are included in the patient's record.

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.

Documentation Templates for Sleep Disorder

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

OSA diagnosis in a sleep clinic

Specialty: Pulmonology

Required Elements

  • AHI score
  • Oxygen saturation levels
  • Anatomical contributors

Example Documentation

Patient diagnosed with severe OSA (AHI 32) confirmed by polysomnography, with oxygen nadir 82%.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has sleep apnea.
Good Documentation Example
Severe obstructive sleep apnea (AHI 32) confirmed by in-lab polysomnography on 03/15/2025, with oxygen nadir 82%.
Explanation
The good example provides specific diagnostic criteria and test results.
