What Osteomyelitis Foot ICD codes can I use?

If you’re looking for Osteomyelitis Foot ICD codes, you’ll be spoiled for choice because there’s a lot! To give you an idea of what you can expect, we will list the basic Osteomyelitis Foot-related ICD-10 codes you can pick.

What you need to do first is determine what kind of Osteomyelitis of the foot your patient is dealing with. Note that all Osteomyelitis ICD-10 codes for feet have ankle and foot in their names. Here they are:

  1. M86.079 - Acute hematogenous osteomyelitis, unspecified ankle and foot
  2. M86.179 - Other acute osteomyelitis, unspecified ankle and foot
  3. M86.279 - Subacute osteomyelitis, unspecified ankle and foot
  4. M86.379 - Chronic multifocal osteomyelitis, unspecified ankle and foot
  5. M86.479 - Chronic osteomyelitis with draining sinus, unspecified ankle and foot
  6. M86.579 - Other chronic hematogenous osteomyelitis, unspecified ankle and foot
  7. M86.679 - Other chronic osteomyelitis, unspecified ankle, and foot
  8. M86.8X7 - Other osteomyelitis, ankle and foot

All codes mentioned above, except for the last one, are unspecified. What is unspecified is if the problem is in the left ankle and foot or the right.

There are no specific ICD-10 codes for cases where both sides are affected, so if you’re handling patients with Osteomyelitis for both feet, you can use these codes. Otherwise, you’ll have to pick more specific codes when you’ve confirmed if the affected side is the left or right.

Item 8 doesn’t have ICD-10 codes specific to the right or left ankle and foot.

Are these Osteomyelitis Foot ICD codes billable?

Yes. All of the aforementioned Osteomyelitis Foot-related ICD-10 codes are valid and billable. The specific codes for the left ankle and foot and those for the right are also useful and billable.

Clinical information about Osteomyelitis:

Osteomyelitis is the term healthcare professionals use when referring to the infection of the bone. Bacteria and fungi cause this infection, and what it does is that it causes bone marrows to swell. These swellings are painful.

  • Those with Osteomyelitis will likely have the following symptoms:
  • They lose their appetite
  • They will have fevers
  • They will sweat a lot
  • They will feel chills
  • They will feel nauseated and may vomit from time to time
  • They will have pain in their lower back
  • Their movement can be painful and limited
  • There will be pus in the affected area

Osteomyelitis requires immediate treatment because it can lead to unwanted complications such as stunted growth in children and the emergence of abscesses. The worst is bone death, characterized by the complete absence of blood flow to the bone, which may lead to the loss of the affected limb. In the case of this subject, that would be the foot (and, by extension, the ankle).

Synonyms include:

  • Acute osteomyelitis of the foot
  • Acute osteomyelitis of ankle and foot
  • Acute osteomyelitis of metatarsal
  • Acute osteomyelitis of phalanx of toe
  • Acute osteomyelitis of talus
  • Chronic osteomyelitis of the foot
  • Chronic osteomyelitis of ankle and foot
  • Chronic osteomyelitis of the foot with draining sinus
  • Chronic osteomyelitis of ankle and foot with draining sinus

Commonly asked questions

What’s the difference between Acute and Chronic Osteomyelitis?

Acute Osteomyelitis is an infection of the bone that just suddenly happens, while Chronic Osteomyelitis is characterized by being resistant enough to (most) treatments that it doesn’t go away.

What are the best ways to treat and manage Osteomyelitis of the Foot?

Healthcare professionals will administer pain-relieving medicine to lessen the pain caused by the swelling. They will also administer antibiotics and antifungals to deal with the bacteria and fungi that caused the infection.

If abscesses have formed, professionals will drain the pus using a needle.

In severe cases, surgery might be needed to remove the dead tissues and bones.

If surgery is performed on the foot, what can patients expect from it?

If healthcare professionals remove dead tissue and bone from the foot. The patient will be at risk of having a bone deformity as a result. If the infection shows signs of spreading to other parts of the body, the healthcare professional will recommend amputating the foot.
