Is M62 a billable ICD-10-CM code?

No. M62 is a non-billable header code. Code to a higher level of specificity using one of its child codes.

Where does M62 sit in the tabular list?

Diseases of the musculoskeletal system and connective tissue (M00-M99), in the block Disorders of muscles (M60-M63).

What cannot be coded together with M62?

M62 carries an Excludes1 note, which means the conditions it lists can never be coded together with it on the same encounter.

M62 — Other disorders of muscle

Non-billable headerICD-10-CM

M62 is a non-billable header ICD-10-CM code for other disorders of muscle. It cannot be billed on its own: choose one of the more specific child codes below.

Excludes1 — never code together

These conditions cannot occur together. Billing both on the same encounter is a denial.

alcoholic myopathy (G72.1)
cramp and spasm (R25.2)
drug-induced myopathy (G72.0)
myalgia (M79.1-)
stiff-man syndrome (G25.82)

Excludes2 — not included here, but may coexist

The excluded condition is not part of this code, but a patient can have both. You may code both.

nontraumatic hematoma of muscle (M79.81)

Other codes that can never be billed with M62

These codes carry an Excludes1 note pointing at M62. The conflict binds both ways, but ICD-10-CM only writes it down on one side — so you would not find this by reading M62 alone.

M24.5Contracture of joint
M62.2Nontraumatic ischemic infarction of muscle
M62.5Muscle wasting and atrophy, not elsewhere classified
M62.81Muscle weakness (generalized)
M79.ANontraumatic compartment syndrome
R26Abnormalities of gait and mobility
R53.1Weakness
R53.2Functional quadriplegia

Risk adjustment

M62 does not map to an HCC and does not risk-adjust under CMS-HCC V28. That is normal — most ICD-10 codes do not. It still needs to be coded correctly; it just will not move a RAF score.

Code to one of these instead M62

8 child codes. Green means billable.
