Check your 2010 consultation coding savvy.

Find out if you’re set to properly code your physician’s consultation services this year by tackling three problems and their solutions.

Check With Your MAC for Guidance

When your physician sees a Medicare inpatient and would have used an inpatient consultation code, this year you should report an initial hospital care code (99221-99223). If the E/M service and documentation do not meet the requirements of an initial inpatient hospital care code, however, your coding will now depend on your Medicare Administrative Contractor’s (MAC) or carrier’s policy.

Problem: The lowest initial hospital care code (99221) requires a detailed history and detailed exam. When your physician’s documentation does not reach this level, there is a question as to what CPT codes you should use.

Option 1: Some MACs/carriers have stated that you should use the subsequent hospital care codes (99231-99233). “Our MAC (Highmark) has actually stated to not use 99499 (Unlisted evaluation and management service) for consultations and to use subsequent care codes,” says Barbara J. Cobuzzi, MBA, CPC, CENTC, CPC-H, CPC-P, CPC-I, CHCC, president of CRN Healthcare Solutions, a coding and reimbursement consulting firm in Tinton Falls, N.J., and senior coder and auditor for The Coding Network. She adds that instructions about whether or not to use 99499 seem to be MAC-by-MAC specific right now.

Option 2: Other MACs, however, have instructed practices to use the Not Otherwise Classified (NOC) code 99499, says Quinten A. Buechner, MS, MDiv, CPC, ACSFP/ GI/PEDS, PCS, CCP, CMSCS, president of ProActive Consultants in Cumberland, Wis.

For example, WPS Medicare states on its Web site: “Many providers have questioned the use of a subsequent care code when the provider does not meet the requirements of an initial care code. Wisconsin Physicians Service (WPS) Medicare advises the use of Not Otherwise Classified (NOC) code 99499 as stated in the Internet-Only Manual (IOM).”

“Check with your contractor,” Buechner advises. “Code 99499 is the correct coding choice by CPT rules.” Some payers, such as Highmark, don’t seem to like that coding, however, so you need to know what code(s) your payers want you to use.

Important: Because five levels of inpatient consults are now billed using only three levels of inpatient E/M visits, some practices are seeking crosswalks that refer them from consult codes to E/M codes. But you should not rely on any such guides as the final word. Instead, when the practitioner performs an E/M service, report the code “that most appropriately describes the level of services provided,” notes MLN Matters article MM6740.

Stick With Two Letters for Admitting Physician

Admitting physicians now have a new modifier for their initial inpatient service. As of Jan. 1, if you’re billing for the admitting physician you must append modifier AI (Principal physician of record) to the initial visit code. This will denote the admitting physician who is overseeing the patient’s care, “as distinct from other physicians who may be furnishing specialty care,” according to CMS Transmittal 1875.

Example: A trauma surgeon admits from the emergency room a patient who was involved in a motor vehicle accident and calls in an orthopedic surgeon to perform a consult for multiple fractures in the patient’s leg. The trauma surgeon would report 99221-99223 (Initial hospital care, per day, for the evaluation and management of a patient …) with modifier AI appended. The orthopedic surgeon then bills 99221-99223 with no modifier for his initial examination of the patient whether the visit represents a consultation or a new visit.

Remember: The new modifier is made up of two letters. “Some people are interpreting the new modifier as a one,” Cobuzzi says. “But it’s two letters, A and I,” she reminds coders. Think: A-eye.

Skip 99241-99255 for Medicare, Even as Secondary

Don’t even think about billing a consult to Medicare — even if the claim is to a Medicare secondary payer (MSP).

The challenge: Medicare may have scratched consultations codes off its list of payable services, but many other insurers did not follow suit. This dual system leaves you in a quandary when your physician performs a consultation, and the primary non-Medicare insurer pays for the consultative service, but the secondary payer is Medicare.

The MSP “will not pay for consults,” says Samantha Daily, a medical biller for a practice in Portland, Ore.

Official word: MLN Matters article MM6740 indicates the following: “In MSP cases, physicians and others must bill an appropriate E/M code for the services previously paid using the consultation codes [99241-99255, Office or other outpatient consultation …]. If the primary payer for the service continues to recognize consultation codes” you should bill for secondary payment from Medicare in one of the following two ways:

• Bill the primary payer using an E/M code (not a consultation code), and then report the amount paid by the primary payer, along with the same E/M code, to the MSP for determination of whether additional payment is due; or
• Bill the primary payer using a consult code, and then report the amount paid by the primary payer, and change the code to the non consult E/M code (that is equal to the consultation code/service documented and paid), to the MSP for determination of whether you are owed additional payment.

Potential snag: In some cases the physician may not know whether a hospitalized patient is on Medicare or another insurance when he documents his consultation and determines code assignment for the billing department. You will need to be able to glean an appropriate E/M code from your physician’s consult documentation if the patient ends up also having Medicare as secondary insurance.
