H02.4-H02.43Primary Range
Ptosis of eyelid
This range includes codes for different types of ptosis, which is the primary condition described as eyelid droop.
Other specified disorders of eyelid
This range includes conditions like dermatochalasis, which can be confused with ptosis but are distinct.
Congenital ptosis
This code is used when ptosis is present at birth, indicating a congenital condition.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| H02.40 | Unspecified ptosis of eyelid | Use when the type of ptosis is not specified after a complete workup. |
|
| H02.41 | Mechanical ptosis of eyelid | Use when ptosis is caused by external factors like tumors or scarring. |
|
| H02.42 | Myogenic ptosis of eyelid | Use when ptosis is due to muscle weakness, such as in myasthenia gravis. |
|
| H02.43 | Paralytic ptosis of eyelid | Use when ptosis is due to nerve paralysis, such as in CN III palsy. |
|
| H02.89 | Other specified disorders of eyelid | Use for eyelid disorders that do not involve true ptosis. |
|
| Q10.0 | Congenital ptosis | Use when ptosis is congenital. |

H02.40Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Eyelid Droop to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code H02.40.
Impact
Clinical: May lead to unnecessary surgery., Regulatory: Non-compliance with payer requirements., Financial: Denial of claims for lack of medical necessity.
Mitigation Strategy
Ensure visual field tests are performed and documented.
Impact
Reimbursement: May lead to denial of claims for ptosis surgery., Compliance: Incorrect coding can result in audits., Data Quality: Affects accuracy of clinical data.
Mitigation Strategy
Reserve H02.89 for non-ptotic lid disorders.
Impact
Reimbursement: Claims may be denied for lack of specificity., Compliance: Non-compliance with coding guidelines., Data Quality: Reduces clarity in patient records.
Mitigation Strategy
Always append -RT/-LT or -E1/-E3.
Impact
Lack of detailed documentation for ptosis surgery.
Mitigation Strategy
Ensure all documentation includes MRD1, visual fields, and functional impact.
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.
