What is the ICD-10 code for axillary hyperhidrosis?

The ICD-10 code for primary focal hyperhidrosis of the axilla is L74.510. It requires documentation of specific location and severity.

How is secondary hyperhidrosis coded?

Secondary hyperhidrosis is coded with L74.52, following the code for the underlying condition. Proper sequencing is essential.

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.	Gravimetric measurement >20 mg/min in men Failed treatment with prescription antiperspirants
L74.512	Primary focal hyperhidrosis, palms	Use for patients with excessive sweating localized to the palms, confirmed by starch-iodine test.	Positive starch-iodine test Gravimetric measurement >30 mg/min
L74.52	Secondary focal hyperhidrosis	Use when hyperhidrosis is secondary to another medical condition.	Documentation of underlying condition Temporal relationship with the secondary condition

Documentation & Coding Risks

Avoid these common issues when documenting Hyperhidrosis.

Lack of specific location documentation

Impact

Clinical: May lead to inappropriate treatment decisions., Regulatory: Non-compliance with coding standards., Financial: Potential claim denials or reduced reimbursement.

Mitigation

Always document the specific location of hyperhidrosis., Use specific codes rather than unspecified ones.

Using unspecified codes when specific ones are available

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

Always use the most specific code available for the condition.

Incorrect sequencing of secondary hyperhidrosis

Impact

Reimbursement: Incorrect sequencing can lead to claim denials., Compliance: Failure to follow coding rules., Data Quality: Inaccurate representation of patient conditions.

Mitigation

Code the underlying condition first, followed by the hyperhidrosis code.

Use of unspecified codes

Impact

Unspecified codes can trigger audits due to lack of specificity.

Mitigation

Ensure documentation supports the use of specific codes.
