Section 13A - Additional Claims and Billing Information


The CPT4 codes for lesion treatments include specific verbiage that needs to be considered in determining whether more than one unit of service or line of service can be billed for a code and if any other codes can be billed with it.

Listed below are the CPT4 codes and the maximum number of units that should be reported on a claim for a date of service.

Code Verbiage Maximum Units
11055 Paring or cutting of benign hyperkeratotic lesion (e.g., corn or callus); single lesion 01
11056  Two to four lesions 01
11057  More than four lesions 01
17000 Destruction (e.g., laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curretement), premalignant lesions (e.g., actinic keratoses); first lesion 01
17003  Second through14th lesion, each (list separately in addition to code for first lesion) 13
17004  Destruction (e.g., laser surgery, electrosurgery, cryosurgery, chemosurgery, surgical curretement), premalignant lesions (e.g., actinic keratoses), 15 or more lesions  01
17110  Destruction by any method of flat warts, molluscum contagiosum, or milia; up to 14 lesions 01
17111  15 or more lesions
  • No more than one of the following codes can be reported for an encounter:11055, 11056, 11057
  • 17003 can only be billed with 17000.  Do not report 17004 in conjunction with codes 17000 or 17003
  • Code 17111 cannot be reported with 17110


Please be sure to use the appropriate CPT codes when billing mammography to differentiate diagnostic from screening.

Diagnostic codes should be used when the procedure is ordered because of a suspicion of breast disease (due to symptoms or clinical findings), patient history of breast cancer or biopsy proven breast disease.

Screening Mammography

A screening code should be used when the procedure is done as a baseline or on a routine basis.

Multiple, Bilateral, and Multiple Bilateral Procedures

In accordance with Current Procedural Terminology (CPT) guidelines, bilateral procedures should be billed on one line only, utilizing the modifier 50; enter one as 01 in the units field and bill your total bilateral charge.

Bilateral Billing Examples

  • Bilateral breast reconstruction – report as code 19357 with modifier 50 on one claim line with 01 in the units field.
  • Bilateral lower and upper blepharoplasties – report as:
    •  15820 with modifier 50 on the first claim line with 01 units
    • 15822 with modifier 50 on the second claim line with 01 units

Note: For bilateral services, do not bill modifier LT/RT or any other site-specific modifier other than 50.

Multiple Procedures
Separate billing is allowed for multiple procedures performed on the same day that add significant time or complexity and are not incidental or an integral part of the primary procedure. The primary procedure is reimbursed at the fee schedule amount; eligible secondary procedures are reimbursed at 50 percent.

Multiple procedures that involve the same service performed more than once (such as CPT code 26100, arthrotomy of each carpometacarpal joint of the left hand), should be billed as five separate lines on the claim form along with the modifier 59 or the HCPCS individual digit modifiers on lines two through five in order to clarify that the additional lines are definitely separate services.

Procedure code descriptions including more than one unit of service provided, (such as code 95117, professional services for allergy immunotherapy, two or more injections, or code 96406, intralesional injections, more than seven lesions), are reported on one line with only one (01) unit.

Final reimbursement is also determined after applying usual edits such as (but not limited to) preauthorization, cosmetic coverage and bundling. In addition, the member’s contract must be active at the time the service is rendered.

Physician/Provider Exceptions (Does not apply to Hospital category reimbursement)

When the CPT code description includes: "each additional" (for example, code 63048, laminectomy, each additional cervical, thoracic, or lumbar segment), report the code on one line with the number of additional segments indicated in the units field.

When the CPT code states: "specify number of tests, doses" (such as code 95024, intradermal tests with allergenic extracts), report the code on one line with the number of tests, doses, etc., indicated in the units field.

Code & Comment

The Code & Comment section on our provider website is an extremely valuable tool that, among other things, can help you determine if a surgical code is bilateral. The Code & Comment tool provides procedure code coverage information including preauthorization requirements and potential medical policies/ protocols that may apply. Code & Comment is available as a "Quick Link" on our secure website. Once selected, a pop-up window will appear. Once you type in a procedure code and select a code type, the coverage information will be returned. A key is also available to explain the abbreviations used in the results. The key also describes some of the fields found in the tool and provides further explanation. The key should be consulted frequently as information can change.

Non-Ionic Low Osmolality Contrast Media

Contrast media will not be considered for separate payment and cannot be billed to the patient. Reimbursement for contrast media is included in the allowance for the radiology service. To maintain accurate records of the use of non-ionic contrast media, use the appropriate CPT/HCPCS code.


Sleep Studies

Modifier 26 (for the physician component/CMS 1500 or 837P claim) and modifier TC (for the hospital or technical services/UB04 or 837I claim) must be used when a sleep study is performed at a hospital or affiliated clinic.
