The diagnosis code Z01.82 for allergy testing is to be used when there is no sign, symptom, or complaint to use to support the testing. A patient presents with history of reactions to bee/wasp/hornet stings and is skin tested.
2018/2019 ICD-10-CM Diagnosis Code Z88.0. Allergy status to penicillin. 2016 2017 2018 2019 Billable/Specific Code POA Exempt. Z88.0 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
The diagnosis code Z01.82 for allergy testing is to be used when there is no sign, symptom, or complaint to use to support the testing. Case Scenario A patient presents with history of reactions to bee/wasp/hornet stings and is skin tested.
Many people are stung and experience an instant reaction that is not necessarily an allergy. This should be a screening since the patient currently has no symptoms and has never been diagnosed with an allergy. A patient presents with history of reactions to bee/wasp/hornet stings and is skin tested.
Z91.030ICD-10-CM Code for Bee allergy status Z91. 030.
Z91. 038 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.
T78.2T78. 2 - Anaphylactic shock, unspecified | ICD-10-CM.
0: Personal history of allergy to penicillin.
919.4 - Insect bite, nonvenomous, of other, multiple, and unspecified sites, without mention of infection | ICD-10-CM.
Some people have a mild allergic reaction and a larger area of skin around the bite or sting becomes swollen, red and painful. This should pass within a week. Occasionally, a severe allergic reaction can occur, causing symptoms such as breathing difficulties, dizziness and a swollen face or mouth.
ICD-10-CM Code for Allergy, unspecified, initial encounter T78. 40XA.
T78.01XAICD-10-CM Code for Anaphylactic reaction due to peanuts, initial encounter T78. 01XA.
Anaphylaxis is a severe, potentially life-threatening allergic reaction. It can occur within seconds or minutes of exposure to something you're allergic to, such as peanuts or bee stings.
Antihistamines. Your doctor may prescribe an antihistamine or recommend an over-the-counter antihistamine such as diphenhydramine (Benadryl) that can block immune system chemicals activated during an allergic reaction.
A doctor will use an FDA-approved skin test for the diagnosis of penicillin allergy. Penicillin skin testing involves applying skin prick and intradermal tests, and a positive and negative control. The test sites are examined for a reaction, and if the testing is negative, he or she will perform an oral challenge.
What about other types of antibiotics? Tetracyclines (e.g. doxycycline), quinolones (e.g. ciprofloxacin), macrolides (e.g. clarithromycin), aminoglycosides (e.g. gentamicin) and glycopeptides (e.g. vancomycin) are all unrelated to penicillins and are safe to use in the penicillin allergic patient.
Penicillin G and penicillin V (phenoxymethylpenicillin) are “natural” penicillins, with a narrow-spectrum of activity due to the development of penicillinases (β-lactamases active against penicillins). Staphylococci, initially sensitive to penicillin G, are now considered highly resistant.
If a reaction to penicillin included skin redness, itching, rash, or swelling, there may have been a penicillin allergy, but these symptoms can also occur for other reasons. Shortness of breath, wheezing, fainting, and chest tightness are all reactions that may indicate anaphylaxis.

Adverse effect of Cephalosporins & other beta-lactam antibiotics T36.1X5A (or D) ( Be sure to document why penicillin testing is required if the reaction was to a Cephalosporin.) T codes require a seventh character of A, D, or S (“S” is rarely used by allergists).
T codes are used when evaluating patients for drug allergies. To code for an adverse effect of a drug that has been correctly prescribed and properly administered:
Penicillin allergy testing can help extend the scope of your practice and provide a valuable service to your patients. But ICD-10 and CPT coding for penicillin allergy testing can be confusing. Here’s what you need to know to get reimbursed for this important service.
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.
Do NOT bill CPT code 95115 and 95117 if the antigen is self-administered by the patient.
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.
