Cracking the ICD-10 Codebook for Audiologists
Tamala S. Bradham
The International Classification of Diseases (ICD) is the standard
diagnostic tool used for clinical purposes, epidemiological research, and
global health management (World Health Organization [WHO], 2014a). ICD allows
administrators, researchers, and health care professionals to monitor and track
mortality and morbidity, incidence and prevalence of diseases, and other health
data, as well as reimbursement for services rendered. Since 1979, the United
States has been using the ninth version (ICD-9-CM [Clinical Modification]),
although there have been multiple attempts to implement ICD-10-CM in the United
States. The current ICD-10 compliance deadline is October 1, 2015. The new
ICD-10 will include the ICD-10-CM and ICD-10-PCS (procedure coding system). The
ICD-10 is owned by WHO. The clinical modification was developed by the Centers
for Disease Control and Prevention (CDC) for use in the U.S. health care
industry. The procedure coding system (i.e., ICD-9-PCS and ICD-10-PCS) was
developed by the Centers for Medicare & Medicaid Services (CMS) for use in
the United States for inpatient hospital settings only. Also of importance, in
May 1990, ICD-10 codes were endorsed by the Forty-third World Health Assembly
and have been adopted by most developed countries. The 11th version, ICD-11, is
now being prepared and will be finalized in 2017.
ICD-10 offers the U.S. health care system several benefits. In ICD-9, there is
a lack of clinical accuracy, a limited number of available codes, and a
restrictive coding structure (CMS, 2014). Furthermore, the United States is
not able to compare mortality and morbidity data globally, as most developed
countries already employ ICD-10 (American Academy of Professional Coders
[AAPC], 2014a; Bowman, 2014). Transitioning will result in moving from 14,025
to 69,823 diagnosis codes and from 3,824 to 71,924 procedure codes (CDC,
ASHA has developed a number of resources to help audiologists
transition to ICD-10, including an ICD-9 to ICD-10 online mapping tool that
allows one to enter an ICD-9 code, which is then mapped to the appropriate
ICD-10 code(s). ASHA also has mapping
spreadsheets for audiology codes and a list of ICD-10 audiology codes. To
more about ICD-10 for audiology, please visit ASHA's website.
ICD-10 and Documentation
In surveys of health care leaders on major
IT challenges in health care organizations over the next 3 years, ICD-10
implementation is listed as the number one concern and documentation is listed
second (Letourneau, 2013). Nachimson Advisors (2011) estimated increased
documentation costs associated with an ICD‐10 implementation ranging "from
$44,000 for a small practice to $1.76 million for a large practice" (p. 5).
For ICD-10 coding, thorough, timely, and succinct documentation of a
patient's visit will be necessary to minimize claim denials (Carr, 2013; Hertz,
2013; Husty & Newell, 2013; Leenheer, 2012; Levy, 2013). It will be
essential for audiologists to document using very specific diagnostic and
treatment terminology. Some states or payers may require greater specificity,
laterality, stages of healing, cause and location of the injury, treatments
tried, and acute or chronic disease state, to name a few examples in clinical
documentation (AAPC, 2014b; see Appendix A for an example).
reported that health care providers are not currently documenting information
that will be necessary for appropriate ICD-10 coding, which will ultimately
affect reimbursement under the new codes. With the current ICD-9 system, the
most common reasons for improper payments during a recovery audit (by recovery
audit contractors [RAC]) were (1) services did not meet medical necessity
criteria, (2) services were incorrectly coded, and (3) supporting documentation
that was submitted did not support the ordered service (CMS, 2012). It is
plausible that, with ICD-10 coding, RAC may see a rise in incorrect coding and
insufficient documentation. A field study by the American Health Information
Management Association (AHIMA; 2003) found that, although ICD-10-CM codes could
be applied to medical records without any changes to documentation practices,
coding specificity would be improved if documentation was better.
Does This Mean for Audiology Practices?
To help audiologists be
successful with the transition from ICD-9 to ICD-10, ASHA (2014a) developed an
ICD-10-CM Preparation Checklist. Checklist items include (1) training, (2)
better documentation, and (3) monitoring and communicating.
Clinical and administrative staff will require significant
time learning new codes and work flows. The learning curve is expected to be
steep for both clinicians and administrative staff (AAPC, 2014b). AAPC reported
that inadequate training could result in "reduced productivity levels for as
long as 6 months due to increased re-work for denied claims, adjustments, and
pended claims, and coders directing an increasing amount of queries to
physicians when documentation is not adequate to support the higher level of
specificity required with ICD-10" (AAPC, 2014b, p. 9). Having a thorough
understanding of the ICD-10 codes will be essential, especially because many
practices do not have coders to determine which codes would maximize
reimbursement and meet compliance standards. It is also important to know that
ICD-10 codes for hearing loss are very different than ICD-9 hearing loss codes.
For example, for a sensory hearing loss, ICD-9 codes used would have been
389.11 for bilateral sensory hearing loss or 389.17 for unilateral sensory
hearing loss. For ICD-10, the clinician will use H90.3 Sensorineural
hearing loss, bilateral or H90.41 Sensorineural hearing loss,
unilateral, right ear, with unrestricted hearing on the contralateral
side if the patient has hearing loss in the right ear and normal hearing
in the left ear or H90.42 Sensorineural hearing loss, unilateral, left
ear, with unrestricted hearing on the contralateral side if the hearing
loss is in the left ear and there is normal hearing in the right ear. If the
patient has a different type of hearing loss in each ear, then the clinician
will use H90.5 Unspecified sensorineural hearing loss and H90.8
Mixed conductive and sensorineural hearing loss, unspecified if the
patient has a sensorineural hearing loss in the right ear and a mixed hearing
loss in the left ear. There is a proposal before the National Center for
Health Statistics to add new codes for when an audiologist uses "restricted
hearing on the contralateral side"; however, there will be no revisions until
2016 at the earliest.
Based on case history and
presenting complaints, audiologists need to determine what test(s) will
address the reason(s) for the patient's visit or what activities will address
the treatment goals/plan. The procedures or interventions performed and billed
should be based on the patient's presenting complaints and should be medically
necessary. The diagnosis should support the patient's complaint(s) and the
procedure(s) performed. In the event the test results are normal, the
diagnosis code should report the signs and symptoms of the patient's
Documentation should include the following components:
- date and time of when the evaluation and treatment were
- history/background and presenting complaints,
- procedures and activities to be performed to address the
- assessment/interpretation of the evaluation and
- recommendations/plan of care to address the findings,
- signature of the provider.
When coding for diagnosis,
audiologists should use as many ICD-10 codes as necessary to substantiate
medical necessity for the visit. If the payer requires Z
codes, here are some case examples for how these can be used when
test results are normal:
Example 1: Child comes in for
a hearing test prior to a speech-language evaluation. The parent does not have
any concerns about hearing but does not know why the child is not talking. The
audiology test results are normal. Use F80.1 Expressive language disorder.
Example 2: Toddler passed newborn hearing screening but has
a risk factor. Toddler comes in at 12 months for audiology follow-up
Scenario 1. Test results are normal. History reveals a
family history of congenital hearing loss. Use Z01.10 Encounter for examination
of ears and hearing without abnormal findings AND Z82.2
Family history of deafness and hearing loss.
Scenario 2. Test
results are inconclusive. History reveals that the toddler underwent ECMO.
(OAEs and tympanograms are normal; sound field at 2,000 Hz is at 20 dB HL.) Use
Z01.10 Encounter for examination of ears and hearing without abnormal findings
AND Z92.81 Personal history of extracorporeal membrane
Scenario 3. Test results are inconclusive.
History reveals prematurity and low birth weight. (Note: Documentation would
need to specify weight and gestational age. OAEs are normal; tympanograms are
flat; sound field at 2000 Hz is at 30 dB HL.) Use Z01.110 Encounter for hearing
examination following failed hearing screening OR Z01.118
Encounter for examination of ears and hearing with other abnormal findings
AND P07.36 Preterm newborn, gestational age 33 completed weeks
AND P07.17 Other low birth weight newborn, 1750-1999
For assistance with mapping ICD-9 codes to ICD-10 codes or vice
versa, please refer to ASHA's Mapping Tools (2014b) as well as ICD-10-CM
Diagnosis Codes Related to Hearing and Vestibular Disorders for assistance
with learning the code (2014c). With extensive training and thorough
documentation, audiologists should be well-positioned to remain viable during
the transition from ICD-9 to ICD-10.
To date, there have been no studies that have
specifically evaluated the denial rates and timeliness of reimbursement for
services in audiology practices with ICD-10 implementation. Audiology
practices will more than likely experience an increase in denial rates and
prolonged duration before receiving reimbursement as the health care industry
works through the transition. Thus, to manage ICD-10 implementation and cash
flow, it will be necessary to have oversight of the denials using a monthly
scorecard system that tracks completed tasks associated with ICD-10 and number
of denials (HFMA, 2013). Health care systems also will need to develop a
process for managing errors and resolving vendor issues (CMS, 2014).
With ICD-10 implementation, sharing success stories, highlighting people
who have been "champions" in the process, and being transparent with staff and
patients on how the health care system is handling ICD-10 will be pivotal to
engaging people in the process and minimizing financial impacts to the system.
Audiologists cannot overcommunicate about this system change.
At some point, the United States will transition to a new ICD
system. It is essential for audiologists to learn as much as they can about
ICD-10 codes, review their current documentation systems and determine how to
prepare for potential changes, and have a dashboard/monitoring system to keep
track of the claims and denials for proactively managing this transition. ASHA
offers, in addition to previously mentioned resources, a checklist
to determine ICD-10 readiness.
To minimize delayed payments and to
maximize reimbursement with ICD-10, Leenheer (2012) recommended that clinicians
(1) complete an assessment of existing documentation and develop an action plan
from the findings, (2) implement an easy-to-use electronic documentation
system, and (3) obtain education and ongoing trainings. Documentation of the
patient's visit is "key to a successful transition to ICD-10" (Leenheer, 2012,
p. 112). There are several tools and training materials available to help with
this transition (ASHA, 2014a, b, c).
The benefits of ICD-10 include (1)
improved quality of care; (2) potential cost savings from increased accuracy of
payments and reduction of unpaid claims (i.e., fewer rejected claims); (3)
improved tracking of public health data; and (4) upgrades to improve IT data
integrity, fraud detection, and cost analysis capabilities. While this change
to ICD-10 does come at a price, many of the projected financial challenges can
be mitigated with proper planning, training, and IT management. The potential
benefits over the long term cannot be overlooked.
