CPT® defines two sets of consultation codes: outpatient/office consults using 99241 through 99245 and inpatient/nursing facility consults using codes 99251 through 99255.

The Center for Medicaid and Medicare Services (CMS) defines a consult in this way

Specifically, a consultation service is distinguished from other evaluation and

management (E/M) visits because it is provided by a physician or qualified

nonphysician practitioner (NPP) whose opinion or advice regarding evaluation

and/or management of a specific problem is requested by another physician or

other appropriate source.  The qualified NPP may perform consultation services

within the scope of practice and licensure requirements for NPPs in the State in

which he/she practices.

The citation goes on to say that the request for the consultation and the specific reason for the consult, shall be documented in both the requesting and the consulting clinician's note. And finally, after the consultation is finished, a copy of the report is returned to the requesting clinician.

This is where we get the four Rs of consultation. It requires a request from another healthcare professional, and that request should be documented in both the requesting and the consulting clinician's note. It requires a specific, medically necessary reason. After the physician has rendered the opinion, then a copy of the report is returned to the requesting clinician. So, we often say you need R’s for a consultation.

Remember: it's only a consult if you say it's a consult and the criteria of the consultation are met. The CMS definition states that the intent of the consultation is asking the other physician or qualified NPP for “advice, opinion, a recommendation, suggestion, direction, or counsel, et cetera, in evaluating or treating a patient, because that individual has expertise in a specific medical area beyond the requesting professional's knowledge.”

The manual continues that you may bill a consultation based on time if the criteria for billing based on time are met.  In order to bill an E/M service based on time, counseling must dominate the visit.  Document the total time of the office visit, the fact that more than 50% of the visit was spent in that discussion and the nature of the discussion.  (See also billing services based on time in Codapedia.)

Be careful about the semantics of consultation. “I had the pleasure of seeing your patient today in my office,” and, “Thank you for allowing me to participate in the care,” do not document a request for opinion.

Use words that are defined in the CMS manual to describe a consultation: request, assessment, consultation, evaluation, opinion, rather than words like referral, pleasure and participation, which don't indicate as explicitly that there was a consult.

Medicare Guidance Changes for E/M Services
October 11th, 2023 - Wyn Staheli
2023 brought quite a few changes to Evaluation and management (E/M) services. The significant revisions as noted in the CPT codebook were welcome changes to bring other E/M services more in line with the changes that took place with Office or Other Outpatient Services a few years ago. As part of CMS’ Medicare Learning Network, the “Evaluation and Management Services Guide” publication was finally updated as of August 2023 to include the changes that took place in 2023. If you take a look at the new publication (see references below),....
Can We Score Interpretation of an EKG Towards E/M Medical Decision Making?
October 10th, 2023 - Aimee Wilcox
When EKGs are performed in the facility setting or even in the physician's office, what are the requirements for reporting the service and who gets credit for scoring data points for Evaluation and Management (E/M) medical decision making (MDM)? Let's take a look at a few coding scenarios related to EKG services to get a better understanding of why this can be problematic.
Accurately Reporting Signs and Symptoms with ICD-10-CM Codes
October 5th, 2023 - Aimee Wilcox
Coders often find themselves unsure of when to report a sign or symptom code documented in the medical record. Some coders find their organization has an EHR that requires a working diagnosis, which is usually a sign or symptom, be entered to order a test or diagnostic study or image. Understanding the guidelines surrounding when signs and symptoms should be reported is the first step in correct coding so let's take a look at some scenarios.
The 2024 ICD-10-CM Updates Include New Codes for Reporting Metabolic Disorders and Insulin Resistance
September 19th, 2023 - Aimee Wilcox
Diabetes is a chronic disease that just seems to consistently be increasing instead of improving resulting in a constant endeavor by medical researchers to identify causal effects and possible treatments. One underlying or precipitating condition that scientists have identified as a precipitating factor in the development of diabetes is insulin resistance, which is a known metabolic disorder. As data becomes available through claims reporting, additional code options become possible with ICD-10-CM.
Documenting and Reporting Postoperative Visits
September 12th, 2023 - Aimee Wilcox
Sometimes we receive questions regarding documentation requirements for specific codes or coding requirements and we respond with information and resources to support our answers. The following question was recently submitted: Are providers required to report postoperative services on claims using 99024, especially if there is no payment for that service? What documentation is required if you are reporting an unrelated Evaluation and Management (E/M) service by the same physician during the postoperative period? 
Understanding Gastroesophageal Reflux Disease and ICD-10-CM Coding
August 22nd, 2023 - Aimee Wilcox
Gastroesophageal reflux disease or GERD for short, is a disease that impacts millions of Americans on a weekly basis. Symptoms are uncomfortable, as are some of the tests used to diagnose it, but understanding the disease, tests, and treatments helps us better understand how to code the disease using ICD-10-CM codes.
