The WHO developed a temporary ICD-10
emergency code (U07.1) for the new coronavirus which has since been named the
2019 novel coronavirus (COVID-19). In
the United States, the National Center for Health Statistics (NCHS), which is
part of the Centers for Disease Control and Prevention (CDC), made an
unprecedented decision to implement a new code for COVID-19 effective April 1,
2020.
U07.1 is the code that has been
implemented for ICD-10-CM. It was felt
that there was an immediate need to capture the specificity afforded by
initiating the new code now rather than waiting until fall. It is important to recognize that the new
code (U07.1) is NOT retroactive. It can
only be assigned for discharges or dates of service on or after 4/1/2020. It is also worth noting that this code and
the guidance supplied apply to all patient types, inpatient and outpatient. U07.1 should be assigned for confirmed cases
of COVID-19 which means that physician documentation that the patient has
COVID-19 is sufficient. Coding
professionals are also instructed that presumptive positive cases should be
coded as confirmed. Presumptive positive
is a term that is used when a state or local test has returned positive but it
hasn’t been confirmed by the CDC.
Confirmation testing by the CDC is no longer being conducted.
U07.1 will be assigned first with the
manifestations listed additionally. This
is a sequencing directive according to the “Use additional code” note in the
Tabular List. This differs from the
interim guidance that is listed below when coding for the virus with dates
prior to 4/1/2020.
The primary MS-DRGs that will be obtained
when U07.1 is assigned as a principal diagnosis are MS-DRGs 177-179 which are Respiratory
infections and inflammations with MCC, CC, or neither.
The following Official Coding Guidelines
supplement was issued providing direction on appropriate coding.
Exposure to COVID-19
When exposure to COVID-19 is a
possibility but is ruled out, assign code Z03.818 Encounter for observation for
suspected exposure to other biological agents ruled out.
When exposure to a confirmed case of
COVID-19 occurs, assign code Z20.828 Contact with and (suspected) exposure to
other viral communicable diseases.
Bear in mind, that the following coding
guidance applies to coding cases prior to 4/1/2020. It is noteworthy that B97.29 is not specific
to COVID-19. There are over 30 different
strains of coronavirus, and this code would apply to all. It has been recommended that
facility-specific guidelines be implemented to use B97.29 only for COVID-19
cases so that data can be captured accurately.
Coding pneumonia due to COVID-19
J12.89
Other viral pneumonia
B97.29
Other coronavirus as the cause of diseases classified elsewhere
Acute Bronchitis due to COVID-19
J20.8
Acute bronchitis due to other specified organisms
B97.29
Other coronavirus as the cause of diseases classified elsewhere
If
the bronchitis is not otherwise specified assign J40 with B97.29 when due to
COVID-19
Lower respiratory infection due to
COVID-19
J22
Unspecified acute lower respiratory infection
B97.29
Other coronavirus as the cause of diseases classified elsewhere
If the respiratory infection is not otherwise specified assign
J98.8 with B97.29 when due to COVID-19
ARDS due to COVID-19
J80
Acute respiratory distress syndrome
B97.29
Other coronavirus as the cause of diseases classified elsewhere
Signs and symptoms
For
the signs and symptoms without a definitive diagnosis of COVID-19, assign the
appropriate sign or symptom code only.
For example, R05 for cough.
A few additional points. First, provider documentation of uncertain
terms in conjunction with COVID-19 like “possible”, “suspected”, or “probable”,
mean we do not assign B97.29 even for inpatients. Instead, the signs or symptoms should be coded. This follows the same advice we have for
coding for Zika virus. Second, when
coding for COVID-19, because the site has generally been respiratory, it would
not be appropriate to assign code B34.2 Coronavirus infection, unspecified. Third, in order to capture positive cases, it
is recommended that facility-specific guidelines be initiated to hold the
coding of cases until the results have been returned with this recommendation
specific only to COVID-19 cases. Be
aware that physicians do not have to go back in their documentation to link a
respiratory condition and a positive COVID-19 test. If there is a positive test result, coders
may assign U07.1. This advice is specific
to COVID-19 code assignment only and does not apply to the coding of other laboratory
tests.
Further, new guidance states that when a
patient has signs or symptoms that are indicative of COVID-19 and the provider
suspects the patient may have it, then Z20.828 can be assigned even if it not
specifically stated that the patient has been exposed.
There are three codes for laboratory
testing for coronavirus:
CPT
Code
- 87635 Infectious agent detection
by nucleic acid (DNA or RNA);severe acute respiratory syndrome coronavirus 2
(SARS-CoV-2) (Coronavirus disease [COVID-19]), amplified probe technique
HCPCS
Level II Codes
- U0001 Used when billing to CDC
testing labs
- U0002 Used when billing to non-CDC
testing labs
Coding professionals can reference the
CDC/NCHS and American Hospital Association websites for additional information
and to find the Official Coding Guidelines supplement and FAQ that address this
topic. This information was current as
of 4/28/2020 with the possibility that future changes or revisions will be
made. Coding professionals are urged to
monitor official coding sites for updated information on a regular basis.
