Valid for Submission
H70.10 is a billable diagnosis code used to specify a medical diagnosis of chronic mastoiditis, unspecified ear. The code H70.10 is valid during the fiscal year 2022 from October 01, 2021 through September 30, 2022 for the submission of HIPAA-covered transactions.
The ICD-10-CM code H70.10 might also be used to specify conditions or terms like caries of mastoid, chronic inflammation of mastoid cavity, chronic mastoiditis, chronic suppurative mastoiditis, fistula of mastoid , injury of mastoid, etc.
Unspecified diagnosis codes like H70.10 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.
The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:
- Caries of mastoid
- Chronic inflammation of mastoid cavity
- Chronic mastoiditis
- Chronic suppurative mastoiditis
- Fistula of mastoid
- Injury of mastoid

The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.

The General Equivalency Mapping (GEM) crosswalk indicates an approximate mapping between the ICD-10 code H70.10 its ICD-9 equivalent. The approximate mapping means there is not an exact match between the ICD-10 code and the ICD-9 code and the mapped code is not a precise representation of the original code.
Information for Patients
Ear infections are the most common reason parents bring their child to a doctor. Three out of four children will have at least one ear infection by their third birthday. Adults can also get ear infections, but they are less common.
The infection usually affects the middle ear and is called otitis media. The tubes inside the ears become clogged with fluid and mucus. This can affect hearing, because sound cannot get through all that fluid.
If your child isn't old enough to say "My ear hurts," here are a few things to look for
- Tugging at ears
- Crying more than usual
- Fluid draining from the ear
- Trouble sleeping
- Balance difficulties
- Hearing problems
Your health care provider will diagnose an ear infection by looking inside the ear with an instrument called an otoscope.
Often, ear infections go away on their own. Your health care provider may recommend pain relievers. Severe infections and infections in young babies may require antibiotics.
Children who get infections often may need surgery to place small tubes inside their ears. The tubes relieve pressure in the ears so that the child can hear again.
