What 95070 covers
This service assesses how the airways respond to an inhaled challenge agent. A pulmonary function laboratory or allergy clinic commonly performs the test, with trained staff administering the agent and measuring pulmonary function at intervals. Methacholine challenge is a familiar example when symptoms suggest asthma but routine testing has not established variable airflow obstruction. The test is distinct from skin testing for allergen sensitization and from measuring exhaled nitric oxide.
Select 95070 for the technical testing, not for interpretation alone. Documentation should identify the clinical indication, challenge agent and protocol, and the pulmonary function measurements and response used to conduct the test. CMS classifies 95070 as a technical-component-only code; a separate code, 95071, covers interpretation and report. Report that interpretation service only when it is performed and documented.

How to choose
- 95076Ingestion challenge
- Use 95076 for an oral ingestion challenge. Use 95070 when the challenge agent is inhaled to assess airway responsiveness.
- 95012FeNO test
- 95012 measures exhaled nitric oxide. It does not describe an inhaled agent challenge with pulmonary function measurements.
- 95004Allergy skin prick test
- 95004 reports percutaneous allergen testing for sensitization; 95070 evaluates the airways’ response to an inhaled challenge agent.
95070 billing questions
When should 95070 be used instead of allergy skin testing?
Use 95070 for an inhaled challenge that evaluates airway responsiveness, such as a methacholine test. Skin testing, including 95004, evaluates sensitization to allergen extracts rather than the airways’ response to inhalation.
Does 95070 include interpretation of the results?
No. CMS identifies 95070 as technical-component-only; 95071 is the separate interpretation-and-report code.
What documentation supports 95070?
Document the reason for the challenge, the inhaled agent and testing protocol, and the pulmonary function measurements and response recorded during testing.
Can 95070 be used for an oral food challenge?
No. 95070 is for an inhaled bronchial challenge. Oral ingestion challenges are reported with the applicable ingestion-challenge codes, such as 95076 and, when appropriate, 95079.
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.
