Q87.1-Q87.11Primary Range

Congenital malformation syndromes predominantly associated with short stature

Q87.11 is specifically for Prader-Willi Syndrome, distinguishing it from other genetic disorders in the same range.

Key Information: ICD-10 code for Prader-Willi Syndrome

Essential facts and insights about Prader-Willi Syndrome

The ICD-10 code for Prader-Willi Syndrome is Q87.11, applicable for confirmed cases.

Primary ICD-10-CM Code for prader willi syndrome

Prader-Willi syndrome
Billable Code

Decision Criteria

clinical Criteria

  • Genetic confirmation of PWS through methylation analysis or FISH.

documentation Criteria

  • Detailed documentation of clinical features and genetic test results.

Applicable To

  • Prader-Willi syndrome confirmed by genetic testing

Excludes

  • Angelman syndrome (Q93.5)
  • Bardet-Biedl syndrome (E72.0)

Clinical Validation Requirements

  • Genetic testing confirming paternal deletion or maternal UPD of chromosome 15
  • Clinical features such as hypotonia, hyperphagia, and developmental delays

Code-Specific Risks

  • Incorrectly coding as Q87.1 without genetic confirmation
  • Failing to document associated comorbidities

Coding Notes

  • Ensure genetic confirmation is documented before coding Q87.11.

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 present as a comorbidity with PWS.

Hypogonadism, unspecified

E23.0
Use when hypogonadism is documented in PWS patients.

Differential Codes

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

Other congenital malformation syndromes

Q87.1
Use Q87.1 only if Prader-Willi syndrome is not confirmed.

Angelman syndrome

Q93.5
Differentiate by genetic testing results showing UBE3A gene involvement.

Documentation & Coding Risks

Avoid these common documentation and coding issues when documenting Prader-Willi Syndrome to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code Q87.11.

Impact

Clinical: Misdiagnosis or delayed treatment., Regulatory: Non-compliance with documentation standards., Financial: Potential claim denials.

Mitigation Strategy

Ensure detailed genetic and clinical documentation., Regular training on documentation standards.

Impact

Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate data collection for research and statistics.

Mitigation Strategy

Ensure genetic confirmation is documented and use Q87.11.

Impact

Lack of detailed genetic test results in patient records.

Mitigation Strategy

Ensure all genetic tests are documented with results and interpretations.

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 Prader-Willi Syndrome, with expert answers to help guide accurate code selection and documentation.

Documentation Templates for Prader-Willi Syndrome

Use these documentation templates to ensure complete and accurate documentation for Prader-Willi Syndrome. These templates include all required elements for proper coding and billing.

Initial Diagnosis of PWS

Specialty: Genetics

Required Elements

  • Genetic test results
  • Clinical features
  • Family history

Example Documentation

Patient presents with hypotonia and feeding difficulties. Genetic testing confirms PWS due to paternal deletion.

Examples: Poor vs. Good Documentation

Poor Documentation Example
Patient has a genetic disorder.
Good Documentation Example
Patient diagnosed with Prader-Willi syndrome confirmed by genetic testing showing 15q11-13 deletion.
Explanation
The good example specifies the condition and provides genetic confirmation.
