Eddiemac,
Asthma is disqualifying, but also waiverable. The following link and text is from NOMI's website. You said that you already checked NOMI, but I'm not sure what you're looking for because this is the only source (that I know of) for official "conditions for a waiver".
Along the lines of what Wink said, "asthma" is a term that is thrown around a lot by doctors and worried moms. I would be reluctant to use the A-word when dealing with the Navy.
As far as "specific NAVY medical numbers": Take the methacholine challenge test.... you don't have Navy Asthma until you fail that test (>15% change in FEV1). Let me know if you have any more specific questions...

15.1 ASTHMA Rev Jul 02
AEROMEDICAL CONCERNS: Asthma symptoms can rapidly progress from minimal to totally disabling. Exposure to smoke or fumes can provoke an attack in susceptible individuals. Positive pressure breathing, breathing of dry air, and +Gz exposure can stimulate bronchospasm in those with hyperreactive airways. 70% of asthmatics also suffer from recurrent sinusitis.
WAIVER: A history of asthma is CD for military service and for aviation training, even if very mild. Waivers for aviation applicants can be recommended if: 1) Asymptomatic for a minimum of five years, 2) Primary physician or specialty consultant document an otherwise normal history and physical examination, 3) Normal baseline PFT's with post bronchodilator (<15% change in FEV1) and Methacholine/Provocative testing being negative.
Designated aircrew with mild intermittent or persistent asthma are considered NPQ. A waiver can be recommended on a case by case basis if the following criteria are met: 1) Internal medicine or pulmonology consult provided with PFT's and examination being normal, 2) asthma must be controlled/stable only on cromolyn sodium, Tilade, or a Leukotriene. Generally consideration will be given for non-high performance aircraft only. Methacholine challenge testing is indicated in those individuals with a questionable history of wheezing. Early response to low doses (less than 10 mg/ml) is considered aeromedically significant. Methacholine challenge testing is not indicated in those individuals with an unquestionable history of asthma, as it can precipitate status asthmaticus. If a waiver is granted, the use of a short acting Beta-agonist is allowed on an as needed basis (rescue mediciation). If needed, temporary grounding is recommended with close flight surgeon follow-up.
INFORMATION REQUIRED: Consultations as above, to include complete pulmonary function testing (PFT) to include baseline, post bronchodilator and methacholine/provocative testing, are necessary for initial waiver requests. Abnormal PFTs must document effect of a post-PFT bronchodilator. Once controlled on a stable dose of cromolyn sodium, tilade or a leukotriene, a repeat PFT is required if the waiver request includes the use of medication.
FOLLOWUP: If triennial submission is directed, it should be accompanied by results of recent PFT. All medications that the individual requires for control of symptoms must be listed on the SF-88, along with their frequency of use.
TREATMENT: Patients may be controlled by cromolyn sodium, tilade, or a leukotriene. The use of beta agonists is CD, waiver only recommended as above for rescue use only! Grounding is required during exacerbations of mild intermediate or persistent. asthma.
DISCUSSION: Reliable diagnosis depends on a substantiated history of cough, wheeze and/or dyspnea lasting more than 6 months, an increase in FEV1 >15% after administration of an inhaled bronchodilator, and/or airway hyperreactivity demonstrated by an exaggerated decrease in airflow induced by a standard bronchoprovocation challenge such as methacholine inhalation or demonstration of exercise-induced bronchospasm.
We make an artificial distinction between individuals who have these symptoms only in the presence of acute upper respiratory infections. These persons do not have the chronic course necessary for the diagnosis of asthma, but may meet the criteria for diagnosis of asthma if symptoms persist.
If diurnal peak expiratory flow rate variability >15%, the condition can be regarded as more than mild in nature. Attacks can be exacerbated by breathing cold and dry air, by respiratory infections and exercise. The first 2 factors may contribute to nocturnal asthma, the effects of which are exacerbated by sleep apnea. Of childhood asthmatics, 50-55% will achieve prolonged remission, but more than half will eventually relapse. The mean age of recurrence is 32.5 years compared to nearly 50 years for those patients who develop asthma as an adult. Reasons for permanent disqualification from flying include persistent, marked bronchial hyperreactivity, frequent episodes of asthma and inadequate control with drugs. The Air Force reports that 25% of the medevacs from Desert Storm were for asthma. Mild asthmatics can remain symptom-free for long periods and then suddenly have a severe exacerbation of the condition when exposed to a trigger.
