How to Code Mild Intermittent Asthma ICD 10 in Clinical Practice
Get paid faster this May Asthma Awareness Month using mild intermittent asthma ICD 10 coding with clear billing steps and fewer denials.
May is Asthma Awareness Month, making it the perfect time to improve your coding accuracy. The coding of asthma must be done closely in relation to the level of severity. The most common, but also most commonly miscoded subtype is mild intermittent asthma. The right Mild Intermittent Asthma ICD 10 code directly affects the acceptance of claims and the health of the revenue cycle. Intermittent asthma is not confused with persistent asthma and this has resulted in denials and audit.
The article is a practical step-by-step guide to coding mild intermittent asthma in clinical practice in a manner that guarantees correct coding. You will learn documentation requirements, payer requirements, the management of denials, and best practices in auditing the Mild Intermittent Asthma ICD 10 code J45.20.
What Is Mild Intermittent Asthma Exactly
Mild intermittent asthma is the least severe form of asthma.The patients experience symptoms two or fewer days a week. Less than two nights per month, nighttime symptoms occur. In between flare ups, the patient has a full-time normalcy. The function of the lungs does not change. There is no daily need of any controller medication. Patients carry just a rescue inhaler and use it when symptoms occur. This clinical picture is important to medical billers and coders. Without knowing the diagnosis, you cannot give a code.
The Mild Intermittent Asthma ICD 10 code is used only when it is documented that there is this pattern. The condition is not intermittent, in case a patient takes daily steroids. When the symptoms are three days a week, the disease is not intermittent. Always ensure that frequency of symptoms is checked prior to coding. Billing Care Solutions educates coders to scan certain phrases. They are symptoms less than twice per week, no daily medications, and normal lung function between episodes. In the absence of these facts, the Mild Intermittent Asthma ICD 10 code can be wrong.
Locating the Correct Mild Intermittent Asthma ICD 10
The right Mild Intermittent Asthma ICD 10 code is J45.20. This code depicts mild intermittent asthma without status asthmaticus. J45 category includes all the types of asthma. Mildred intermittent is specified in the subcategory J45.2. Character 0 (uncomplicated) is the fifth character. Routine office visits should be coded to J45.20. J45.21 is used when the patient has an acute exacerbation. Exacerbation refers to a situation where the symptoms become worse and need rescue medication. Do not confuse J45.20 with J45.30. J45.30 is mild persistent asthma. Chronic asthma involves the use of controller therapy on a daily basis.
The code J45.20 of the Mild Intermittent Asthma ICD 10 code became valid as of October 1, 2015. It is chargeable to all ages. The provider should always ensure that he has reported intermittent severity. Always do not make assumptions on the basis of medication alone. Other providers hand write asthma NOS. In that case, you cannot use J45.20. You need to seek clarification. In order to improve the process, Billing Care Solutions suggests that you have a code reference card at your workstation. Quick reference minimizes errors.
Key Documentation Needed Before Assigning This Code
Prior to you assigning the Mild Intermittent Asthma ICD 10 code, review the medical record of five elements. First, symptom frequency. The note has to mention two days per week or less. Second, the frequency of symptoms in the night. Two nights per month or less. Third, healthy lung functioning between the flare ups. Fourth, no daily controller medication. Fifth, clear reference to intermittent asthma. In case the provider writes asthma, then you cannot add mild intermittent by yourself.
The Mild Intermittent Asthma ICD 10 code is one that requires clinical judgment by the provider. In a known patient, seek out a recent test of asthma control. A score of over 20 is an indication of good control. In the case of a new patient, seek a careful history of symptom patterns. Long term frequency may not be included in the emergency department note. Then, in that instance, code the acute exacerbation first. Use J45.21 instead of J45.20. Billing Care Solutions suggests a documentation checklist. Mark each required element before coding. If any element is missing, query the provider.
How to Rule Out Persistent Asthma Subtypes
There are three levels of persistent asthma. J45.30 is used in mild persistant. Moderate persistent J45.40. Severe persistent uses J45.50. These subtypes have to be excluded to correctly use the Mild Intermittent Asthma ICD 10 code J45.20. The symptoms that last more than two days per week are signs of persistent asthma. Persistent asthma is also indicated by nighttime symptoms that are more than two nights per month. Persistent asthma is pointed at by daily controller medication, including fluticasone. Between exacerbation, abnormal lung functioning reinforces persistent asthma.
In case the patient has been admitted to a hospital due to asthma in the last one year, persistent asthma is more probable. Mild Intermittent Asthma ICD 10 code is not suitable in the case of patients with frequent exacerbations. There is an error made by some coders in which they assigned J45.20 when the provider wrote mild asthma. But mild asthma not mentioned with the word intermittent can indicate mild persistent. Always look out for the word intermittent.
Coding Mild Intermittent Asthma With Status Asthmaticus
Status asthmaticus is a life threatening asthma attack. It is not responsive to the common rescue inhalers. It is an emergency care and usually a hospital care. Do not code J45.20, status asthmaticus, when a patient develops status asthmaticus. Rather, have J45.902 as the main code. J45.902 is unspecified asthma with status asthmaticus. The emergency severity is captured within this code. You can also include a second code of the underlying type of asthma. However, status asthmaticus outshine the intermittent classification. Do not apply J45.21 as well.
It is acute exacerbation not status asthmaticus. Acute exacerbation is responsive to nebulizer treatment. Status asthmaticus does not. When the provider records the status asthmaticus, the Mild Intermittent Asthma ICD 10 code J45.20 is incorrect. Billing Care Solutions recommends coders to seek out and find the key terms such as intubation, ICU admission, and continuous albuterol. These are indicators of status asthmaticus, rather than the normal intermittent asthma.
Linking the ICD 10 Code to E M Services
The E M service level should be supported by the Mild Intermittent Asthma ICD 10 code J45.20. A low level visit will be suitable in a stable patient without exacerbation. Examples are 99212 or 99213 of established patients. The diagnosis warrants a medication check or reviewing an asthma action plan. A patient with an acute exacerbation with a J45.21 coded patient may be suitable with a higher level. The 99281 to 99285 are commonly used in the emergency department visits to exacerbation. Do not associate J45.20 with critical care codes. It would be a compliance risk.
Mild Intermittent Asthma ICD 10 code is used in brief and routine visits. It is not conducive to long services and high medical decision making. In case the provider conducted pulmonary function testing, verify medical necessity. Normal baseline functioning with intermittent asthma may not warrant spirometry. Other payers have made persistent asthma indispensable to get test coverage. According to Billing Care Solutions, the rationale of all tests should be documented. Clinical sense must be made of the connection between the diagnosis and the procedure.
Modifier and Payer Rules for This Diagnosis
The payer codes of the Mild Intermittent Asthma ICD 10 code J45.20 differ. J45.20 of office visits is accepted by Medicare. It is also accepted by most commercial plans. With the diagnosis alone, modifiers are seldom necessary. However service modifiers can be used. A case in point would be modifier 25 of a separately identifiable E M service on the same day as a procedure. When a patient has a nebulizer treatment and an office visit, append modifier 25 to the E M code. Both services are supported by the Mild Intermittent Asthma ICD 10 code.
Observes payer medical policies. There are plans that include J45.20 as non covered of home nebulizer equipment. Only intermittent asthma patients might be eligible to use rescue inhalers. Persistent asthma is oftentimes required to cover the cost of durable medical equipment payers. Always check prior to billing. According to Billing Care Solutions, it is recommended to develop a payer grid. Identify the treatments that are subject to J45.20 in each of the major payers. Includes rescue inhalers, nebulizers and office visits. This will avoid rejections and will enhance cash flow.
Denial Management for This Specific Asthma Code
The Mild Intermittent Asthma ICD 10 code J45.20 falls under three types. Firstly, denial of medical necessity. The payer says that the level of the visit is too high to be diagnosed. An example is that a stable intermittent asthma check has to be billed as a level 4 visit. Right by modifying the visit level. Second, documentation denial. Intermittent severity is not clearly supported in the medical record. Appeal made by producing the note of the provider which indicates the frequency of the symptoms. Third, denial of code mismatch. The procedure code involves unremitting asthma. There are pulmonary rehab codes which require J45.30 or greater. Confirm procedure specific diagnosis requirements prior to billing.
In case of a denial based on the wrong severity, communicate with the provider. Enquire whether the patient is, in fact, persistent. Otherwise, the service will not be covered. The ICD 10 code of Mild Intermittent Asthma is only suitable in the case of very intermittent disease. Billing Care Solutions suggests that the reasons for denials in J45.20 should be tracked separately. Train providers using this data. Most denials can be prevented by better documentation.
Best Practices for Auditing Mild Intermittent Asthma ICD 10
Auditing of Mild Intermittent Asthma ICD 10 code J45.20 on a regular basis enhances compliance. Evaluate a minimum of 20 records in a quarter. Find the documentation of the frequency of the symptoms. Seek documentation of night time symptoms. Ascertain that there is no daily medication of a controller. Check that the patient has not been hospitalized for asthma in the past year. Hospitalization implies continuing or severe asthma. Check the code as well as the age of the patient. In children under five, intermittent asthma coding might be in need of further documentation.
Compare the Mild Intermittent Asthma ICD 10 code to the medication list. The wrong code is when the patient uses a daily inhaled corticosteroid. Design an audit tool that has a basic checklist. Ask these questions. Do you have two or fewer days of symptoms each week? Do you have two or more nighttime symptoms in two nights or less each month? Does he/she have any daily controller medication? Has any hospitalization within the last 1 year? When the answers to all questions are yes, then the correct answer is J45.20. Billing Care Solutions offers asthma coding audit templates. These should be used in order to ensure high accuracy.
