With the implementation of ICD-10-PCS more codes were developed in order to accurately report procedures. Spinal fusion coding is still a problematic coding issue and at times, even a coder’s nightmare. Coders often report only the code for the fusion thinking that one code would include all of the other procedures that are performed. Let’s take a look at a couple of the most common missed procedures associated with spinal fusions coding.
Decompression of the spinal cord/nerve
Coding decompression procedures separately will depend on the documentation by the physician of what body part is being decompressed/released and if there is a distinct surgical objective. If the laminectomy (many times called a decompression) is only performed to reach the site of the planned spinal fusion, then no additional code would be reported. This is true even if the decompression is at the same level as the fusion. The operative note should indicate what is being released/decompressed (spinal cord/nerve). Look for terms such as stenosis, compression, decompression, myelopathy, and radiculopathy to name a few. These are terms that may be hints that a decompression was needed and completed to address a specific diagnosis.
The root operation used to report the decompression is “release.” The definition of release in ICD-10-PCS is “freeing a body part from an abnormal physical constraint by cutting or by use of force.” This means that the restraining tissue may be removed but none of the body part being compressed is taken out. In the case of spinal cord/nerve root compression, the body part that is being freed is the spinal cord or the nerve roots. Whatever is compressing these can be removed to release the compression. The release of spinal cord is only coded once since the spinal cord is classified as a single body part (per spinal level such as cervical, thoracic, lumbar, and lumbosacral). The specific ICD-10-PCS code will depend on the level of the spine the procedure is being performed on.
Discectomy—Excision or Resection
This is performed to remove herniated intervertebral disk in the spine. When a disk is herniated, it may cause pain and numbness due to the material compressing the spinal nerves and/or spinal cord. Most often, the surgeon will only remove a portion of the disk material that is causing the compression or “pinching the nerve.” This would be coded with the root operation “excision.” The definition of excision in ICD-10-PCS is “cutting out or off, without replacement, a portion of a body part.” If the surgeon does remove the entire disk, this is coded with the root operation “resection.” The definition of resection in ICD-10-PCS is “cutting out or off, without replacement, all of a body part.” The discectomy is most often coded in addition to the spinal fusion as there is almost always a separate and distinct diagnosis that requires the discectomy to be performed. The operative note should clearly state what the discectomy is being performed for, and if there is partial or total removal of the disc.
Other Less Common Procedures Missed
- Removal of internal fixation devices
- Computer assisted procedure—Stealth Navigation System
- Monitoring of peripheral nervous electrical activity, intraoperatively
- Removal of previous interbody fusion device
There are so many references available on coding of spinal fusions and associated procedures listed below, and this isn’t even all of them that are available. If in doubt, take time to research these. There are also action plans available that are an excellent reference for coding of spinal fusions.

This would be considered a “mechanical” complication of the stent graft since the MD states it is a fracture of the endograft and it is folded over on itself. I would change T82.898A TO T82.598A for Other mechanical complication of other cardiac and vascular devices and implants, initial encounter. I did not use “displacement” because the surgeon did not state that the graft was displaced, only that it collapsed upon itself causing obstruction.
We interviewed our most productive coders and reviewers, asking them what steps they take to find a rhythm that works for them. This week, we talked with Valerie Abney, CDIP, RHIT, CCS, about the steps she takes to find her routine.
Osteoporosis alone is responsible for over a million fractures every year. Stress fractures are not as common but they do occur. There are more than 1 million total joint replacements in the U.S. each year, so there was a need to create codes for injuries that occur around or near the prosthesis. These are called “periprosthetic” fractures.
Back in April, the Office of the Inspector General (OIG) published a report detailing its findings from a review of two groups of high-risk diagnosis codes, acute stroke and major depressive disorder. The objective was to determine whether selected diagnosis codes submitted to the Centers for Medicare and Medicaid Services for use in CMS’s risk adjustment program complied with Federal requirements.
There seems to be differences of opinions on the issue of a 40w0day gestation Can you clarify if P08.21 should be assigned for 40w0day infant or if it would not be assigned unless the infant’s gestation age was 40w1day or greater?
Coders may find situations where a patient is documented as meeting SIRS or sepsis criteria, or has some clinical indicators reflective of possible sepsis, but the physician never documents sepsis as a diagnosis. Should the coder always query for sepsis in these instances?
In this example, would it be appropriate to code the complication code T82.03XA, Leakage of heart valve prosthesis, initial encounter as the principal diagnosis over the HFpEF (heart failure exacerbation) code?
We interviewed our most productive coders and reviewers, asking them what steps they take to find a rhythm that works for them. This week, we talked with Kerry Atkins, CDIP, CCS‑P, COC, CPC, CPCO, CPMA, CEMC, COBGC, RMB, Physician Services Consultant at HIA, about the steps she takes to find her routine.
A higher CMI corresponds to increased consumption of resources and increased cost of patient care, resulting in increased reimbursement to the facility from government and private payers, like CMS. We know that documentation directly impacts coding.
Answer: I would code 0HPT0NZ for removal of tissue expander from right breast, open and change 0HPT0JZ, removal of synthetic substitute from right breast, open, for removal of the acellular dermal matrix to 0HPT0KZ, Removal of nonautologous tissue substitute from right breast, open approach.
There are certain conditions that have instructional notes in the ICD-10-CM tabular/coding conventions that guide the coder in sequencing. This is especially true when the condition has a common manifestation or underlying conditions of a chronic disease. If there is a “code first” note in the tabular, the coder should follow this instruction and sequence the underlying etiology or chronic condition first followed by the manifestation as an additional diagnosis.
When it comes to coding and documentation, finding your own rhythm can lead to positive results. For our series, Find Your Routine, we interviewed our most productive coders and reviewers and asked them what steps they take to find a rhythm that works for them. This week, we talked with Meghan Schumacher, CPC, CPMA, Provider Coding Consultant at Health Information Associates, Inc., about the steps she takes to find her routine.
Last year, the Office of Inspector General (OIG) performed an investigation that found, “between 2014 and 2016, Medicare Advantage organizations overturned 75% of their preauthorization and payment denials upon appeal,” which is why, at HIA, we always advise our clients to engage in the appeals process.
There may be instances where a coder will suspect the patient has acute kidney injury (AKI), but the physician has failed to document the diagnosis. In another scenario, the physician may have made the diagnosis, but there is a question of clinical validity. In either case, a query would be justified.
Changes to CC/MCC designations included in the proposal could have a potentially dramatic effect on casemix. The presence of a major complication or comorbidity (MCC) or complication or comorbidity (CC) generally is representative of a patient that requires more resources.
How many times have you heard “it only takes one code to get the claim paid”? With the emphasis on the severity of illness and the move toward value-based reimbursement in today’s healthcare climate, it is more important than ever for coders to report all applicable diagnoses. There are three important pieces: what the provider documents, how to the coder interprets that documentation and codes it, and then how it is extrapolated.
The reimbursement landscape is already a complicated one – and the highly-complex claims denials process only adds fuel to the fire. A denied claim is one that has been determined by a payor to be in appropriate. Once a coding specialist amends the errors on a rejected claim, they can resubmit it for consideration. The time-intensive process has a significant impact on the cash flow for any setting in the healthcare environment. They are also very costly to appeal.
When a practitioner documents a diagnosis that does not appear to be supported by the clinical indicators in the health record, a coder has four choices: (1) Code the diagnosis; (2) Ignore the diagnosis; (3) Generate a query to confirm clinical validation of a diagnosis; (4) Follow the facility’s escalation policy for clinical validation.
A California-based healthcare services provider and several of its affiliates have agreed to pay $30 million to resolve allegations they submitted inaccurate information about the health status of beneficiaries enrolled in Medicare Advantage Plans, according to the Department of Justice.
Happy National Volunteer Week! This week we celebrate the impact volunteer work has on building stronger communities. We know that our staff have a positive impact while they’re on the job, and we are proud to share a few ways our #PeopleBehindTheNumbers are taking time to volunteer in their own local communities.
Scrutiny of coding compliance in the growing ambulatory surgical center (ASC) market has increased in recent years from both Medicare and private payers. This will only increase as the Centers for Medicare and Medicaid Services (CMS) moves towards value-based care.
Patients being admitted for acute renal failure due to dehydration have been happening for many, many years now. Typically what happens is a patient gets dehydrated for one reason or another. Once dehydration sets in, it can quickly start to affect many body organs. This can lead to acute renal/kidney failure/injury.
In December 2018, a Pennsylvania for-profit hospital and health system, and its CEO agreed to pay a total of $12.5 million to settle allegations they submitted false claims to Medicare and other federal health care programs for orthopedic surgeries. The settlement resolves allegations that top executives exploited a loophole – AKA modifier 59 – that allowed them to double bill federal healthcare payers for surgeries and ignored coding consultants who advised them that they were improperly billing.
All queries require at least two elements – clinical indicators and a query question. Coders can also include multiple choice options for response or leave the query open-ended for a free text response. The order in which these elements are listed in a query is open to coder or facility preference.
Giving back is an important part of the HIA mission. Each year, HIA employees take a consensus and choose three National charities to support. Individuals can volunteer a portion of their wages to one of the three organizations. HIA Corporate will match each individual donation up to five dollars. We are proud to share with you our 2018 contribution totals combined with HIA matching funds.
One area that coders struggle with is when to report a separate condition code when an already assigned combination code includes the condition. For example, if an obstetric patient is admitted and delivers, and the physician documents “obstetric patient delivered with anemia,” should both code O99.02 Anemia complicating childbirth and D64.9, Anemia, unspecified be coded or should only O99.02 be assigned?
When it comes to coding and documentation, finding your own rhythm can lead to positive results. For our series, Find Your Routine, we interviewed our most productive coders and asked them what steps they take to find a rhythm that works for them. This week, we talked with Donna Cowan, RHIT, CCS, Coding Specialist at Health Information Associates, about the steps she takes to find her routine.
The key to choosing reasonable options for a query response is to remember that the query must stand alone. Any clinical indicators supporting the options must be included in the query itself. In this week’s Query Tip, we provide examples of two queries in which the options for response are not reasonable based on clinical indicators used by coder.
Last week, we looked at tidbits for reporting the ICD-10-CM codes for pregnancy/obstetric records. Now we will look at some for the ICD-10-PCS reporting of these records. In reporting the appropriate ICD-10-PCS codes a coder must know what is included in the terminology of products of conception (POC).
