L74.5-L74.52Primary Range
Focal hyperhidrosis
This range covers focal hyperhidrosis, which is the most common form of hyperhidrosis, affecting specific body areas.
Generalized hyperhidrosis
This code is used for generalized hyperhidrosis, which affects the entire body and is often linked to systemic conditions.

| Code | Description | When to Use | Key Documentation |
|---|---|---|---|
| L74.510 | Primary focal hyperhidrosis, axilla | Use for patients with excessive sweating localized to the axilla, confirmed by gravimetric testing. |
|
| L74.512 | Primary focal hyperhidrosis, palms | Use for patients with excessive sweating localized to the palms, confirmed by starch-iodine test. |
|
| L74.52 | Secondary focal hyperhidrosis | Use when hyperhidrosis is secondary to another medical condition. |

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

Coding Notes
- Ensure documentation specifies the location and severity of sweating.
L74.512 - Primary focal hyperhidrosis, palms
Use for patients with excessive sweating localized to the palms, confirmed by starch-iodine test.
Applicable To
- Palmar hyperhidrosis
Excludes
- Generalized hyperhidrosis (R61)
Clinical Validation Requirements
- Positive starch-iodine test
- Gravimetric measurement >30 mg/min
Coding Notes
Ensure documentation includes specific test results and location.
L74.52 - Secondary focal hyperhidrosis
Use when hyperhidrosis is secondary to another medical condition.
Applicable To
- Hyperhidrosis due to another condition
Excludes
- Primary focal hyperhidrosis (L74.5-L74.51)
Clinical Validation Requirements
- Documentation of underlying condition
- Temporal relationship with the secondary condition
Coding Notes
Ensure proper sequencing with the underlying condition.
Ancillary Codes
Additional codes that should be used in conjunction with the main diagnosis codes when applicable.

Documentation & Coding Risks
Avoid these common documentation and coding issues when documenting Hyperhidrosis to ensure proper reimbursement, maintain compliance, and reduce audit risk. These guidelines are particularly important when using ICD-10 code L74.510.
Impact
Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials or reduced reimbursement.
Mitigation Strategy
Always document the specific location of hyperhidrosis., Use specific codes rather than unspecified ones.
Impact
Reimbursement: Claims may be denied or reimbursed at a lower rate., Compliance: Non-compliance with coding guidelines., Data Quality: Decreased accuracy in health records.
Mitigation Strategy
Always use the most specific code available for the condition.
Impact
Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Failure to follow coding rules., Data Quality: Inaccurate representation of patient conditions.
Mitigation Strategy
Code the underlying condition first, followed by the hyperhidrosis code.
Impact
Unspecified codes can trigger audits due to lack of specificity.
Mitigation Strategy
Ensure documentation supports the use of specific codes.
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.
