Payment for Pathology Services
60 - Payment for Pathology Services
(Rev. 2714, Issued: 05-24-13, Effective: 07-01-12 Implementation: 06-25, 13)
A. Payment for Professional Component (PC) Services
Payment may be made under the physician fee schedule for the professional component of
physician laboratory or physician pathology services furnished to hospital inpatients or
outpatients by hospital physicians or by independent laboratories, if they qualify as the re-
assignee for the physician service.
B. Payment for Technical Component (TC) Services
1. General Rule
Payment is not made under the physician fee schedule for TC services furnished in
institutional settings where the TC service is bundled into the facility payment, e.g.,
hospital inpatient and outpatient settings. Payment is made under the physician fee
schedule for TC services furnished in institutional settings where the TC service is not
bundled into the facility payment, e.g., an ambulatory surgery center (ASC). Payment may
be made under the physician fee schedule for the TC of physician pathology services
furnished by an independent laboratory, or a hospital if it is acting as an independent
laboratory, to non-hospital patients. The physician fee schedule identifies physician
laboratory or physician pathology services that have a TC service.
2. TC Services Furnished by Independent Laboratories to Hospital Inpatients and
Outpatients
• For services furnished on or after July 1, 2012, an independent laboratory may not
bill the A/B MAC (B) (and the A/B MAC (B) may not pay) for the TC of a
physician pathology service furnished to a hospital inpatient or outpatient.
• For services furnished prior to July 1, 2012, payment may be made under the fee
schedule, as noted below, for the (TC) of pathology services furnished by an
independent laboratory to hospital inpatients or outpatients.
CMS published a final regulation in 1999 that would no longer allow independent laboratories
to bill under the physician fee schedule for the TC of physician pathology services. The
implementation of this regulation was delayed by Section 542 of the Benefits and Improvement
and Protection Act of 2000 (BIPA). Section 542 allows the Medicare A/B MAC (B) to
continue to pay for the TC of physician pathology services when an independent laboratory
furnishes this service to an inpatient or outpatient of a covered hospital. This provision is
applicable to TC services furnished January 1, 2001 through June 30, 2012.
For this provision, a covered hospital is a hospital that had an arrangement with an independent
laboratory that was in effect as of July 22, 1999, under which a laboratory furnished the TC of
physician pathology services to fee-for-service Medicare beneficiaries who were hospital
inpatients or outpatients, and submitted claims for payment for the TC to a A/B MAC (B). The
TC could have been submitted separately or combined with the professional component and
reported as a combined service.
The term, fee-for-service Medicare beneficiary, means an individual who:
• Is entitled to benefits under Part A or enrolled under Part B of title XVIII or both;
and
• Is not enrolled in any of the following: A Medicare + Choice plan under Part C of
such title; a plan offered by an eligible organization under §1876 of the Social
Security Act; a program of all-inclusive care for the elderly under §1894; or a social
health maintenance organization demonstration project established under Section
4108 of the Omnibus Budget Reconciliation Act of 1987.
In implementing Section 542, the A/B MACs (B) should consider as independent laboratories
those entities that it has previously recognized as independent laboratories.
An independent laboratory that has acquired another independent laboratory that had an
arrangement of July 22, 1999, with a covered hospital, can bill the TC of physician pathology
services for that hospital’s inpatients and outpatients under the physician fee schedule.
An independent laboratory that furnishes the TC of physician pathology services to inpatients
or outpatients of a hospital that is not a covered hospital may not bill the A/B MAC (B) for the
TC of physician pathology services during the time §542 is in effect.
If the arrangement between the independent laboratory and the covered hospital limited the
provision of TC physician pathology services to certain situations or at particular times, then
the independent laboratory can bill the A/B MAC (B) only for these limited services.
The A/B MAC (B) shall require independent laboratories that had an arrangement, on or prior
to July 22, 1999 with a covered hospital, to bill for the technical component of physician
pathology services to provide a copy of this agreement, or other documentation substantiating
that an arrangement was in effect between the hospital and the independent laboratory as of
this date. The independent laboratory must submit this documentation for each covered
hospital that the independent laboratory services.
C. Physician Laboratory and Pathology Services
Physician laboratory and pathology services are limited to:
• Surgical pathology services;
• Specific cytopathology, hematology and blood banking services that have been
identified to require performance by a physician and are listed below;
• Clinical consultation services that meet the requirements in subsection 3 below; and
• Clinical laboratory interpretation services that meet the requirements and which are
specifically listed in subsection 4 below.
1. Surgical Pathology Services
Surgical pathology services include the gross and microscopic examination of organ tissue
performed by a physician, except for autopsies, which are not covered by Medicare.
Depending upon circumstances and the billing entity, the A/B MACs (B) may pay professional
component, technical component or both.
2. Specific Hematology, Cytopathology and Blood Banking Services
Cytopathology services include the examination of cells from fluids, washings, brushings or
smears, but generally excluding hematology. Examining cervical and vaginal smears are the
most common service in cytopathology. Cervical and vaginal smears do not require
interpretation by a physician unless the results are or appear to be abnormal. In such cases, a
physician personally conducts a separate microscopic evaluation to determine the nature of an
abnormality. This microscopic evaluation ordinarily does require performance by a physician.
When medically necessary and when furnished by a physician, it is paid under the fee
schedule.
For services furnished prior to January 1, 1999, A/B MACs (B) pay separately under the
physician fee schedule for the interpretation of an abnormal pap smear furnished to a hospital
inpatient by a physician. They must pay under the clinical laboratory fee schedule for pap
smears furnished in all other situations. This policy also applies to screening pap smears
requiring a physician interpretation. For services furnished on or after January 1, 1999, A/B
MACs (B) allow separate payment for a physician’s interpretation of a pap smear to any
patient (i.e., hospital or non-hospital) as long as: (1) the laboratory’s screening personnel
suspect an abnormality; and (2) the physician reviews and interprets the pap smear.
This policy also applies to screening pap smears requiring a physician interpretation and
described in the National Coverage Determination Manual and Chapter 18. These services are
reported under codes P3000 or P3001.
Physician hematology services include microscopic evaluation of bone marrow aspirations and
biopsies. It also includes those limited number of peripheral blood smears which need to be
referred to a physician to evaluate the nature of an apparent abnormality identified by the
technologist. These codes include 85060, 38220, 85097, and 38221.
A/B MACs (B) pay the PC for the interpretation of an abnormal blood smear (code 85060)
furnished to a hospital inpatient by a hospital physician or an independent laboratory.
For other hematology codes, payment may be made for the PC component if the service is
furnished to a patient by a hospital physician or independent laboratory. In addition, payment
may be made for these services furnished to patients by an independent laboratory.
Blood banking services of hematologists and pathologists are paid under the physician fee
schedule when analyses are performed on donor and/or patient blood to determine compatible
donor units for transfusion where cross matching is difficult or where contamination with
transmissible disease of donor is suspected.
The blood banking codes are 86077, 86078, and 86079 and represent professional component
only services.
3. Clinical Consultation Services
Clinical consultations are paid under the physician fee schedule only if they:
a. Are requested by the patient’s attending physician;
b. Relate to a test result that lies outside the clinically significant normal or expected range
in view of the condition of the patient;
c. Result in a written narrative report included in the patient’s medical record; and
d. Require the exercise of medical judgment by the consultant physician.
Clinical consultations are professional component services only, i.e., there is no TC service.
The clinical consultation codes are 80500 and 80502.
Routine conversations held between a laboratory director and an attending physician about test
orders or results do not qualify as consultations unless all four requirements are met.
Laboratory personnel, including the director, may from time to time contact attending
physicians to report test results or to suggest additional testing or be contacted by attending
physicians on similar matters. These contacts do not constitute clinical consultations.
However, if in the course of such a contact, the attending physician requests a consultation
from the pathologist, and if that consultation meets the other criteria and is properly
documented, it is paid under the fee schedule.
EXAMPLE: A pathologist telephones a surgeon about a patient’s suitability for surgery based
on the results of clinical laboratory test results. During the course of their conversation, the
surgeon asks the pathologist whether, based on test results, patient history and medical records,
the patient is a candidate for surgery. The surgeon’s request requires the pathologist to render
a medical judgment and provide a consultation. The pathologist follows up his/her oral advice
with a written report and the surgeon notes in the patient’s medical record that he/she requested
a consultation. This consultation is paid under the fee schedule.
In any case, if the information could ordinarily be furnished by a nonphysician laboratory
specialist, the service of the physician is not a consultation payable under the fee schedule.
See the Program Integrity Manual for guidelines for related data analysis to identify
inappropriate patterns of billing for consultations.
4. Clinical Laboratory Interpretation Services
Only clinical laboratory interpretation services, which meet the criteria in subsections C.3.a, c,
and d, are billable under the physician fee schedule. These codes have a PC/TC indicator of
“6” on the Medicare Physician Fee Schedule database. These services are reported under the
clinical laboratory code with modifier 26. These services can be paid under the physician fee
schedule if they are furnished to a patient by a hospital pathologist or an independent
laboratory. Note that a hospital’s standing order policy can be used as a substitute for the
individual request by the patient’s attending physician. A/B MACs (B) are not allowed to
revise CMS’s list to accommodate local medical practice. The CMS periodically reviews this
list and adds or deletes clinical laboratory codes as warranted.
D. Global Billing
Billing globally for services that are split into separate PC and TC services is only possible
when the PC and TC are furnished by the same physician or supplier entity. For example,
where the PC and the TC of a diagnostic service are provided in the same service location, this
is reflected as the address entered into Item 32 on CMS Form 1500, which provides the ZIP
Code to pay the right locality/GPCI. In this case, the physician/entity may bill globally.
However, if the PC and the TC are each provided in different service locations (enrolled
practice locations), the PC and the TC must be separately billed.
Merely applying the same place of service (POS) code to the PC and the TC does not permit
global billing for any diagnostic procedure.
