Allergy, unspecified, initial encounter
T78.40XA is a billable diagnosis code used to specify a medical diagnosis of allergy, unspecified, initial encounter. The code T78.40XA is valid during the fiscal year 2021 from October 01, 2020 through September 30, 2021 for the submission of HIPAA-covered transactions.
Symptoms of a mild allergic reaction can include:
Allergy, unspecified, initial encounter. 2016 2017 2018 2019 2020 2021 2022 Billable/Specific Code. T78.40XA is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes. The 2022 edition of ICD-10-CM T78.40XA became effective on October 1, 2021.
Allergic rhinitis is classified to code 477.1. An atopic food allergy is classified to code 691.8. If the dermatitis was due to food in contact with the skin, assign code 692.5.

The conventions for the ICD-10-CM are the general rules for use of the classification independent of the guidelines. These conventions are incorporated within the Alphabetic Index and Tabular List of the ICD-10-CM as instructional notes.
Code assignment is based on the provider’s documentation of the relationship between the condition and the care or procedure, unless otherwise instructed by the classification. The guideline extends to any complications of care, regardless of the chapter the code is located in. It is important to note that not all conditions that occur during or following medical care or surgery are classified as complications. There must be a cause-and-effect relationship between the care provided and the condition, and an indication in the documentation that it is a complication. Query the provider for clarification, if the complication is not clearly documented.
More than one external cause code is required to fully describe the external cause of an illness or injury. The assignment of external cause codes should be sequenced in the following priority:
The word “with” or “in” should be interpreted to mean “associated with” or “due to” when it appears in a code title, the Alphabetic Index (either under a main term or subterm), or an instructional note in the Tabular List. The classification presumes a causal relationship between the two conditions linked by these terms in the Alphabetic Index or Tabular List. These conditions should be coded as related even in the absence of provider documentation explicitly linking them, unless the documentation clearly states the conditions are unrelated or when another guideline exists that specifically requires a documented linkage between two conditions (e.g., sepsis guideline for “acute organ dysfunction that is not clearly associated with the sepsis”).For conditions not specifically linked by these relational terms in the classification or when a guideline requires that a linkage between two conditions be explicitly documented, provider documentation must link the conditions in order to code them as related.
Counseling Z codes are used when a patient or family member receives assistance in the aftermath of an illness or injury, or when support is required in coping with family or social problems.
When assigning a chapter 15 code for sepsis complicating abortion, pregnancy, childbirth, and the puerperium, a code for the specific type of infection should be assigned as an additional diagnosis. If severe sepsis is present, a code from subcategory R65.2, Severe sepsis, and code(s) for associated organ dysfunction(s) should also be assigned as additional diagnoses.
code from subcategory O9A.2, Injury, poisoning and certain other consequences of external causes complicating pregnancy, childbirth, and the puerperium, should be sequenced first, followed by the appropriate injury, poisoning, toxic effect, adverse effect or underdosing code, and then the additional code(s) that specifies the condition caused by the poisoning, toxic effect, adverse effect or underdosing.
The allergy status is found in the ICD-10-CM Index by looking under history, personal, allergy. The code description does not include personal history, which makes this condition difficult to locate in the Index. The specificity of the known allergy is found under this entry. Allergies can be specified to classes of medications and high-frequency food allergies. Some code examples of allergy status are:
There is an allergy status (patient has a known allergy to a food or substance) and an allergic reaction (patient is having a current reaction to a substance/food item). It is important that the documentation is specific to the circumstances as well as the cause to support accurate code assignment.
The manifestation of the allergic reaction is coded first (e.g. hives or gastrointestinal upset). Use T78.1 when the manifestation is unknown or undocumented.
This physician also noted that patients with allergies should have an action plan for any severe allergic reactions.
Some organizations do not code the allergy information on a routine basis. Determine if your provider or organization captures this information as part of their provider/organization-specific guidelines. Allergic reaction is found under the main term of “allergy” in the ICD-10-CM Index.
Use secondary code (s) from Chapter 20, External causes of morbidity, to indicate cause of injury. Codes within the T section that include the external cause do not require an additional external cause code.
The 2022 edition of ICD-10-CM T78.40XA became effective on October 1, 2021.
CPT codes 95120-95134 describe complete service codes for the combined supply of antigen AND allergy injection provided during a SINGLE encounter. Medicare does NOT cover complete service codes. See the component-billing sample.
Contractors may specify Revenue Codes to help providers identify those Revenue Codes typically used to report this service. In most instances Revenue Codes are purely advisory. Unless specified in the article, services reported under other Revenue Codes are equally subject to this coverage determination. Complete absence of all Revenue Codes indicates that coverage is not influenced by Revenue Code and the article should be assumed to apply equally to all Revenue Codes.
For allergen immunotherapy purposes a dose describes the amount of antigen (s) administered in a single injection from a multi-dose vial.
Please note that not all revenue codes apply to every type of bill code. Providers are encouraged to refer to the FISS revenue code file for allowable bill types. Similarly, not all revenue codes apply to each CPT/HCPCS code. Providers are encouraged to refer to the FISS HCPCS file for allowable revenue codes.
It is the responsibility of the provider to code to the highest level specified in the ICD-10-CM. The correct use of an ICD-10-CM code listed below does not assure coverage of a service. The service must be reasonable and necessary in the specific case and must meet the criteria specified in this determination.
Do NOT bill CPT code 95115 and 95117 if the antigen is self-administered by the patient.
