Question

What if a provider documents arteriovenous malformation (AVM) of the stomach and the patient is 87 years old?  How should this be coded?

Answer

Sometimes, a provider documents a condition, and the ICD-10-CM Alphabetic Index leads the coder to assign a congenital condition.  In this case, it’s AVM of the stomach.

Anomaly

     Arteriovenous NEC

          Gastrointestinal Q27.33

Since the patient is older, look for documentation that states the condition is congenital, inherited, or the patient has had the condition since birth, or other similar terms.  If there is no documentation of the condition being congenital, query the provider for clarification.  If he/she documents that the condition developed later in life, refer to the term ‘acquired’ in the index and follow the instruction.  Acquired AVM of the stomach is coded to angiodysplasia of stomach and duodenum without bleeding (K31.819).

 Anomaly

     Arteriovenous NEC

          Gastrointestinal Q27.33

               Acquired – see Angiodysplasia

Angiodysplasia

     Stomach (and duodenum) K31.819

Did You Know?

Through the Medicare Learning Network (MLN), CMS has developed an interactive education tool titled Medicare Preventive Services (MLN006559 January 2024). This tool is meant to help providers properly provide and bill Medicare prevention services (i.e., bone mass measurement, colorectal screening, lung cancer screening).

For each Preventive Service listed in the tool, you will find the following information as applicable to the service:

• National Coverage Determination (NCD),
• HCPCS and CPT codes specific to the service provided,
• ICD-10-CM diagnosis codes,
• Telehealth eligibility,
• Coverage requirements,
• Frequency requirements, and
• Medicare Beneficiary (patient) cost sharing.

   

  You will also find answers to the following questions:

• How do I determine the last date a patient got a preventive service, so I know if they’re eligible to get the next service and it won’t deny due to frequency edits?
• When can CMS add new Medicare preventive services?
• My patients don’t follow up on routine preventive care. How can I help them remember when they’re due for their next preventive service?
  • CMS provides a link to a Preventive Services Checklist that you can give your patients.
  • Note, CMS also highlights preventive services with an apple in the official U.S. government Medicare Handbook, Medicare and You. You will find information about preventive services in the 2024 Edition of this handbook on pages 30-55.
• What’s a primary care setting?

   

  Why It Matters?

  This tool was revised in January 2024. Following are two examples of what has been revised:  

   

  Annual Wellness Visit

  New HCPCS code G0136 (Administration of a standardized, evidence-based social determinants of health risk assessment tool, 5-15 minutes) has been added as well as the following “Other Notes:”

• The implementation date for SDOH Risk Assessment claims is July 1, 2024,
• The billing HCPCS code is G0136,
• Add modifier 33 to an SDOH, G0136, performed on the same day as the Annual Wellness Visit to waive copayment and deductible,
• G0136 is covered once a year with copayment and deductible waived, and
• The AWV can be an optional community health integration (CHI) initiating visit when the provider identifies any unmet SDOH needs that prevent the patient from doing the recommended personalized prevention plan.

Flu Shot

Starting January 1, 2024, Medicare pays an additional payment for in-home flu shot administration under certain circumstances.

What Can You Do?

• Read all the revisions made to this tool in January in the February 15, 2024 edition of MLN Connects,
• Use this tool to identify service specific applicable coverage requirements (NCD), HCPCS/CPT codes, and ICD-10-CM diagnosis codes, and
• Share this tool with key stakeholders at your facility.

Did You Know?

Livanta, the National Medicare Claim Review Contractor, samples claims for review monthly for short stay reviews (SSRs) and higher weighted DRG (HWDRG) reviews. As part of their Provider Education efforts, they publish a monthly newsletter called The Livanta Claims Review Advisor.

The first Claims Review Advisor newsletter was published two years ago this month in February 2022. Livanta noted in that newsletter that it is meant “to share its review findings and provide guidance to healthcare organizations…each month’s content will highlight areas of interest for medical coders, billing professionals, clinical documentation improvement (CDI) professionals, physicians, and other practitioners.” Topics alternate between SSRs and HWDR reviews each month.

Why It Matters?

Livanta recently released the January 2024 edition of The Livanta Claims Review Advisor with a focus on SSRs for electrolyte abnormalities. You will find error rates by MS-DRG, example scenarios of specific electrolyte abnormalities (i.e., hyperglycemic emergencies), and guidance for documenting “the reasonableness of a two-midnight expectation at the time of inpatient admission: regardless of the MS-DRG.

Error Rates

Overall, Livanta completed 1,985 reviews for dates of service from October 2021 through December 2023 for the following MS-DRGs:

• MS-DRG 637: Diabetes with MCC,
• MS-DRG 638: Diabetes with CC,
• MS-DRG 639: Diabetes without CC/MCC,
• MS-DRG 640: Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes with MCC (error rate 10.20%), and
• MS-DRG 641: Miscellaneous Disorders of Nutrition, Metabolism, Fluids and Electrolytes without MCC.

MS-DRG 641 had the highest reported error rate at 11.60%.

How Big is the Pool of Claims?

Based on claims data provided by our sister company RealTime Medicare Data (RTMD), in the CMS FY 2023 (October 1, 2022 through September 30, 2023) for all fifty states and Washington D.C. combined, there were 73,497 claims that grouped to one of the above MS-DRGs. The total payment made to providers for this group of claims was $481,535,832.43.

Note, claims with a discharge disposition of expired (20), transfer to another acute care facility (02), transfer to a short-term general hospital with planned acute hospital inpatient readmission (82), left against medical advice (07), and hospice election (50 & 51) have been excluded from this data as CMS considers these to be “unforeseen circumstances.” I have included MS-DRG specific claims data in the table at the end of this article.

What Can You Do?

• Read the January 2024 of The Livanta Claims Review Advisor and share with key stakeholders at your facility.
• Review a sample of short stay claims to determine if documentation supported the inpatient admission or if care could have been provided on an outpatient basis.
• View past editions of this newsletter at https://www.livantaqio.cms.gov/en/ClaimReview/Provider/provider_education.html, and
• If you have not signed up to received Livanta’s publications, I encourage you to do so at https://www.livantaqio.cms.gov/en/ClaimReview/Provider/bulletin.html.

Question

Documentation in the record revealed the patient had Celiac Artery Stenosis. The encoder assigned Celiac Artery Compression Syndrome (I77.4) which was not documented in the record. Is code I77.4 the correct code for Celiac Artery Stenosis?

Answer

No, because Celiac Artery Compression Syndrome is compression caused by a fibrous band of the diaphragm and is not the same as Celiac Artery Stenosis.  The appropriate code for Celiac Artery Stenosis is Stricture of an Artery (I77.1). Coding Clinic advises to search for the more appropriate code if the code title assigned from the Index does not correctly describe the condition.

January is Thyroid Awareness Month. This article highlights the differences between hypothyroidism and hyperthyroidism and the next steps to thyroid awareness. 

Hypothyroidism, Just the Facts

Hypothyroidism is when your thyroid gland does not make enough thyroid hormones to meet your body’s needs and without enough thyroid hormones, many of your body’s functions slow down.

• Nearly 5 out of 100 Americans aged 12 years and older have hypothyroidism. Most cases are mild, or a patient has few obvious symptoms.
• Women are more likely to develop hypothyroidism,
• This disease is more common in people over 60 years old,
• Reasons making you more likely to develop hypothyroidism include:
  • A prior thyroid problem, such as a goiter,
  • Prior surgery or radioactive iodine to correct a thyroid problem,
  • Prior radiation treatment to thyroid, neck, or chest,
  • A family history of thyroid disease,
  • Being pregnant in the past 6 months,
  • Having Turner syndrome (a genetic disorder that affects women), and
  • Is more likely to occur if you have other health problems (i.e., celiac disease, pernicious anemia, Type 1 or Type 2 diabetes, rheumatoid arthritis, or lupus).
• Symptoms of hypothyroidism can include fatigue, weight gain, trouble tolerating cold, joint or muscle pain, dry skin, thinning hair, heavy or irregular menstrual periods, fertility problems, slower heart rate and depression. Note, many of these symptoms are common and do not necessarily mean you have a thyroid problem.
• Hypothyroidism can contribute to high cholesterol. If your cholesterol is elevated, you should get tested for hypothyroidism.

   

  Hyperthyroidism, Just the Facts

  Hyperthyroidism is when your thyroid gland makes more thyroid hormones than what your body needs and with too much thyroid hormone, many of your body’s functions speed up.

• About 1 out of 5 Americans aged 12 years and older have hyperthyroidism.
• Like hypothyroidism, women are more likely to develop hyperthyroidism and this disease is more common in people over 60 years old,
• Reasons making your more likely to develop hyperthyroidism include:
  • A family history of thyroid disease,
  • Other health problems (i.e., vitamin B deficiency, Type 1 or Type 2 diabetes, or primary adrenal insufficiency),
  • Eating large amounts of foods containing Iodine,
  • Taking medications containing Iodine,
  • Use of nicotine products, and
  • Being pregnant in the last 6 months.
• Symptoms of Hyperthyroidism can include weight loss despite increased appetite, rapid and irregular heartbeat, nervousness, irritability, trouble sleeping, fatigue, shaky hands, muscle weakness, sweating or trouble tolerating heat, frequent bowel movements, or a goiter. Note, in older adults this disease can be mistaken for depression or dementia.
• If left untreated, this disease can cause serious health problems (i.e., irregular heartbeat that can lead to blood clots, stroke, heart failure, Graves’ ophthalmopathy, thinning bones, osteoporosis, muscle pain and menstrual cycle and fertility issues).

What Can You Do?

Even though the symptoms you may experience with hypothyroidism and hyperthyroidism are common and may not be related to a thyroid problem, it is important to mention them during an appointment with your doctor.

Your doctor can check for thyroid disease during a standard physical exam by palpation of the thyroid gland and there are two standard blood tests that your doctor may recommend. One measures your thyroid hormone level (T4) and another measures thyrotropin (TSH) which is a hormone secreted from the pituitary gland that controls how much thyroid hormone your thyroid makes.

Treatment for thyroid disease will be specific to the type and severity of the thyroid disorder and the age and overall health of the patient.
