Neurosurgery Coding Alert

If you-ve tried adding modifier 21 onto a 99245 or 99223 that took longer than usual, rejoice - CPT 2009 eliminates this pitfall by taking you directly into prolonged services codes.

Providers and billers often forget that CPT allowed modifier 21 (Prolonged evaluation and management services) only for the highest-level E/M code in a category, says Lynn A. Brown, CPC, director of physician coding and reimbursement at

Children's Health System in Birmingham, Ala. Per CPT 2008, Appendix A, you would use the modifier only with "the highest level of E/M service within a given category" and only on an E/M code.

"If the time documented did not exceed 30 minutes above the CPT allotted time," you could possibly append modifier 21 to the E/M, Brown explains.-"Because modifier 21 was redundant in some cases and confusing to some, eliminating this

modifier will simplify the decision."

Using a 99354-99359 code, rather than modifier 21, provides a more quantified description with established RVUs. Carriers had to determine how much, if any, additional payment to allow for use of modifier 21.

"The prolonged E/M service codes clarify whether it was face-to-face time with the patient and specify exactly the time parameters involved," explains Jennifer Swindle, RHIT, CCS-P, CPC-EM-FP, CCP, director of coding compliance/charge

entry for QLIMG, and director of the coding and compliance division of PivotHealth LLC in Garden City, N.Y.

You should code the level of care based on medical necessity and time. Report E/M services 30 minutes beyond the usual service for direct and indirect patient care using prolonged services codes 99354-99359.

Example: A visit, in which the E/M medical necessity level meets the criteria for 99214 (Office or other outpatient visit for the evaluation and management of an established patient ... physicians typically spend 25 minutes face-to-face with the

patient and/or family), takes 60 minutes.

This visit would be eligible for an additional prolonged service code of 99354 (Prolonged physician service in the office or other outpatient setting requiring direct [face-to-face] patient contact beyond the usual service; first hour [List separately in

addition to code for office or other outpatient evaluation and management service]) with 99214, Brown says.

2008 method: In the office setting, you could have used modifier 21 on only 99215 (Office or other outpatient visit for the evaluation and management of an established patient ...), not 99214, but the visit's medical necessity might not have

warranted reporting this level of care.

If you were one of the lucky few getting paid for 99215-21, CPT 2009 will disappoint you. Prolonged service of less than 30 minutes total duration on a given date is not separately reported because the work involved is included in the total work of

the E/M codes, according to new CPT notes for 99354 and 99356. Therefore, the AMA deleted modifier 21, considering it obsolete given the use of the prolonged service codes 99354--99359.

Loss of payment on soon-to-be-included prolonged services, however, will probably not be widespread. Many payers do not recognize modifier 21 for additional payment, Brown notes.

Expect an easier time getting paid for prolonged services that a physician provides face-to-face to a patient. Most payers recognize prolonged services codes for direct patient care, but not for indirect or non-face-to-face care, Brown says.
