Wiki Otitis Externa vs. swimmers ear vs. other ear conditions

[Brenda1973]

I am looking for a link or guidance to reporting the correct ICD-10 code for all of the ear infection/manifestations. What would be the difference between Otitis externa and swimmers ear?
There seems to be so many of these visits this time of year with swimming and upper resp. infections.
Need help with Internal/external/acute/chronic/ect. just looking for some information to clarify what needs documented for each individual scenario.
Thank-you!

here is what I found on chronic:
Chronic otitis media H65.23 — COM is diagnosed when there is a subacute or chronic tympanic membrane perforation which occurs in the setting of a chronic ear infection or recurrent infections.

●Benign COM is characterized by a tympanic membrane perforation without accompanying drainage.

●In COM with effusion (or chronic serous otitis media) there is continuous, typically straw colored, serous drainage through the perforated tympanic membrane.

●Chronic suppurative otitis media (CSOM) is defined by chronic purulent drainage through the perforated tympanic membrane.

Some otologists alternatively classify COM based on the presence of either a chronic tympanic membrane perforation ("COM mucosal disease") or cholesteatoma ("COM benign squamous disease"). The term "active" is also used if there is otorrhea and "inactive" if it remains dry.

High fever and advanced chronic mucoid otitis media of both ears, which is the child’s third ear infection this year: If the pediatrician classifies the ear infection as chronic, use the chronic mucoid otitis media diagnosis (H65.33, Chronic mucoid otitis media, bilateral) as the primary diagnosis, and the fever (R50.9) as the secondary diagnosis. Technically, you do not have to list the signs and symptoms at all if you have the definitive diagnosis, but if you use both, list the definitive diagnosis first.
