ICD-10 codes for asthma

ICD-10-CM asthma codes encode severity (intermittent vs mild/moderate/severe persistent) and acuity (uncomplicated, with exacerbation, with status asthmaticus). J45.909 is the fallback, not the default.

Sådan vælger du den rigtige kode

Document severity classification at least annually and code it: intermittent (J45.2-), mild persistent (J45.3-), moderate persistent (J45.4-), severe persistent (J45.5-). During an attack, the sixth character changes: -1 for exacerbation, -2 for status asthmaticus. Severity plus acuity together (e.g. J45.41, moderate persistent with exacerbation) is the fully specific code.

Dokumentationseksempel

Asthma review. Using salbutamol 4–5 times weekly, waking with cough twice weekly — consistent with moderate persistent asthma. Today wheezing with peak flow 65% of best after URTI. Prednisolone burst started; stepped up to medium-dose ICS/LABA.

FAQ

What is the ICD-10 code for asthma?

The ICD-10 code for asthma is J45.909 (Unspecified asthma, uncomplicated). Related codes include J45.20, J45.40, J45.50. Confirm the most specific code against the documented clinical detail before billing.

When should I avoid J45.909?

Whenever severity is documented or documentable. Reliever frequency and night symptoms in the note support a persistent-severity code, which reflects the patient’s actual disease burden.

What is the difference between exacerbation and status asthmaticus?

An exacerbation is an acute worsening responding to treatment; status asthmaticus is a severe attack not responding to standard bronchodilator therapy — an emergency, coded with the -2 sixth character.

Can AI map my asthma note to the specific code?

Yes. Notat extracts reliever use, night waking, and acute findings as clinical facts and proposes the severity- and acuity-specific J45 code with its evidence.
