Trichiasis: Coding Guidelines
This article provides information about how to submit claims for correction of trichiasis (removal of inwardly growing eyelashes).
CPT codes 67820 and 67825:
Correction of Trichiasis, by epilation
CPT codes 67830 and 67835:
Correction of Trichiasis, incision of lid margin
Coding Guidelines:
- When the above codes are submitted on a claim, report the codes per eye, and not per eyelash or per eyelid
- When performed unilaterally, the quantity-billed field (days/units) must be 'one'
- When performed bilaterally on the same date of service, submit on the same detail line with CPT modifier 50. The quantity-billed field (days/units) must be 'one.' If it is necessary to submit the bilateral service on separate lines or claims, submit the correct CPT code with HCPCS modifier RT on one line, the CPT code with HCPCS modifier LT on a separate line. Submit the quantity-billed field as 'one' on each detail.
- Incorrectly coded services will be rejected as unprocessable (remark code MA130). These claims must be corrected and resubmitted as new claims. You may not submit Redetermination Requests for these billing errors.
