What is the ICD-10 code for choroidal nevus?

The ICD-10 code for a choroidal nevus is D31.31 for the right eye and D31.32 for the left eye. These codes are used to document benign neoplasms of the choroid.

When should H35.8 be used with a choroidal nevus?

H35.8 should be used as a secondary code when subretinal fluid is present with a choroidal nevus, as confirmed by OCT imaging.

Documentation & Coding Risks

Avoid these common issues when documenting Choroidal Nevus.

Failing to document the size of the nevus.

Impact

Clinical: Inadequate monitoring of potential growth., Regulatory: Non-compliance with documentation standards., Financial: Potential for denied claims due to insufficient detail.

Mitigation

Always measure and record the basal diameter and thickness.

Using unspecified laterality code D31.30 when laterality is known.

Impact

Reimbursement: May lead to denied claims or reduced reimbursement., Compliance: Non-compliance with coding guidelines., Data Quality: Decreases accuracy of patient records.

Mitigation

Always document and code the specific eye affected.

Omitting H35.8 when subretinal fluid is present.

Impact

Reimbursement: Potential under-coding affecting DRG assignment., Compliance: Failure to fully capture the clinical picture., Data Quality: Incomplete patient data.

Mitigation

Ensure subretinal fluid is documented and coded with H35.8.

Unspecified laterality

Impact

Using unspecified codes when laterality is documented.

Mitigation

Ensure laterality is always documented and coded.
