What 95180 covers

An allergist uses rapid desensitization to gradually increase a patient’s exposure to a medication that has caused or may cause an immediate hypersensitivity reaction. Examples include antibiotics, aspirin, chemotherapy agents, and biologic drugs when desensitization is needed to permit treatment. The clinician administers escalating doses under close observation for reactions, commonly in a monitored outpatient setting or hospital environment equipped to respond to acute symptoms.

Report 95180 by the hour, supported by documentation of the procedure’s duration and the dosing protocol. The record should identify the medication, dose escalation, monitoring, any reactions, and whether the protocol was completed or stopped. Physician supervision and interpretation are included in the service. This is distinct from routine scheduled allergen immunotherapy injections, which do not involve a prolonged medication desensitization protocol.

This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

95180 billing questions

When should 95180 be used instead of routine allergy injection codes?

Use 95180 for a prolonged, monitored escalation of medication doses to desensitize a patient. Routine allergen immunotherapy injections are reported with codes such as 95115 or 95117.

How are units reported?

The code is reported by the hour. Document the procedure’s duration and dosing protocol to support the units billed.

Is physician supervision separately reported?

Physician supervision and interpretation are included in 95180. The clinician’s monitoring and response to dose-related symptoms should be documented as part of the procedure.

What details should the medical record include?

Document the medication being desensitized, the dose-escalation steps, procedure duration, patient monitoring, any reaction and treatment, and whether the protocol was completed.

Can 95180 be used for ordinary venom or environmental allergy shots?

No. Those are routine allergen immunotherapy services; 95180 describes a rapid desensitization procedure involving stepwise medication dosing.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
