| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| G70.01 | Myasthenia gravis with (acute) exacerbation | Use when the patient experiences an acute exacerbation of myasthenia gravis. |
|
| G70.00 | Myasthenia gravis without (acute) exacerbation | Use when the patient has stable myasthenia gravis without exacerbation. |
|
| G70.2 | Congenital myasthenia | Use for congenital myasthenic syndromes confirmed by genetic testing. |

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

Essential facts and insights about Myasthenia Gravis
Primary ICD-10-CM Codes for myasthenia gravis
Decision Criteria
clinical Criteria
- Presence of acute exacerbation symptoms
Applicable To
- Myasthenic crisis
Excludes
- Congenital myasthenia (G70.2)
Clinical Validation Requirements
- Documented acute exacerbation requiring increased treatment
- Respiratory failure or bulbar symptoms
Code-Specific Risks
- Incorrectly coding without evidence of exacerbation
Coding Notes
- Ensure documentation specifies 'acute exacerbation' to justify this code.
G70.00 - Myasthenia gravis without (acute) exacerbation
Use when the patient has stable myasthenia gravis without exacerbation.
Applicable To
- Stable myasthenia gravis
Excludes
- Myasthenia gravis with (acute) exacerbation (G70.01)
Clinical Validation Requirements
- Stable symptoms without recent exacerbation
Coding Notes
Ensure documentation supports stable condition without exacerbation.
G70.2 - Congenital myasthenia
Use for congenital myasthenic syndromes confirmed by genetic testing.
Applicable To
- Congenital myasthenic syndromes
Excludes
- Acquired myasthenia gravis (G70.00, G70.01)
Clinical Validation Requirements
- Genetic testing confirmation
- Neonatal onset
Coding Notes
Ensure genetic testing results are documented.
Ancillary Codes

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Myasthenia Gravis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code G70.01.
Impact
Clinical: Leads to inadequate treatment planning., Regulatory: Non-compliance with coding standards., Financial: Potential for claim denials.
Mitigation Strategy
Ensure detailed documentation of symptoms and treatment., Use specific codes for exacerbation status.
Impact
Reimbursement: Incorrect coding can lead to denied claims., Compliance: Non-compliance with coding guidelines., Data Quality: Inaccurate clinical data representation.
Mitigation Strategy
Ensure documentation clearly states whether an exacerbation is present.
Impact
Inadequate documentation of exacerbation status can lead to audit issues.
Mitigation Strategy
Implement detailed documentation protocols for exacerbation status.
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.
