I70.338 — Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of other part of lower leg

BillableUnspecifiedCC

Is I70.338 billable?

Yes, but I70.338 is an unspecified code. I70.338 is a valid, billable ICD-10-CM code for encounters from October 1, 2026 through September 30, 2027. However, I70.338 is an unspecified or catch-all code. Payers apply additional scrutiny to unspecified codes and many deny them when the medical record supports a more specific option, so check the documentation before selecting I70.338 — the more specific alternatives are listed below.

Which MS-DRGs does I70.338 group to?

I70.338 sits in MDC 05 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.

  • 299Peripheral Vascular Disorders with MCCmedical
  • 300Peripheral Vascular Disorders with CCmedical
  • 301Peripheral Vascular Disorders without CC/MCCmedical

As a secondary diagnosis, I70.338 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is I70.338 listed in the Alphabetic Index?

These are the routes through the Alphabetic Index that lead to I70.338. They show the wording a clinician may have documented, which often differs from the Tabular description.

  • Arteriosclerosis, arteriosclerotic › extremities › bypass graft › leg › right › with › ulceration › lower leg NEC (diffuse) (obliterans) (of) (senile) (with calcification)
  • Arteriosclerosis, arteriosclerotic › with › critical limb ischemia › bypass graft › leg › right › with › ulceration › lower leg NEC (diffuse) (obliterans) (of) (senile) (with calcification)

Excludes1 — never code together — inherited from I70.3

The conditions below can never be reported together with I70.338 on the same claim. An Excludes1 note means the two conditions cannot occur in the same patient, so reporting both is a coding error.

  • embolism or thrombus of bypass graft(s) of extremities (T82.8-)

Use additional code — inherited from I70

Report an additional code alongside I70.338 to fully describe the condition. I70.338 is sequenced first.

  • code to identify:
  • exposure to environmental tobacco smoke (Z77.22)
  • history of tobacco dependence (Z87.891)
  • occupational exposure to environmental tobacco smoke (Z57.31)
  • tobacco dependence (F17.-)
  • tobacco use (Z72.0)

Use additional code — inherited from I70.3

Report an additional code alongside I70.338 to fully describe the condition. I70.338 is sequenced first.

  • code, if applicable, to identify chronic total occlusion of artery of extremity (I70.92)

Use additional code — inherited from I70.33

Report an additional code alongside I70.338 to fully describe the condition. I70.338 is sequenced first.

  • code to identify severity of ulcer (L97.-)

Excludes2 — not included here — inherited from Chapter 9

The conditions below are not part of I70.338, but a patient may have both at the same time. When documentation supports it, I70.338 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
  • systemic connective tissue disorders (M30-M36)
  • transient cerebral ischemic attacks and related syndromes (G45.-)

Excludes2 — not included here — inherited from I70

The conditions below are not part of I70.338, but a patient may have both at the same time. When documentation supports it, I70.338 and the excluded code may both be reported.

  • arteriosclerotic cardiovascular disease (I25.1-)
  • arteriosclerotic heart disease (I25.1-)
  • atheroembolism (I75.-)
  • cerebral atherosclerosis (I67.2)
  • coronary atherosclerosis (I25.1-)
  • mesenteric atherosclerosis (K55.1)
  • precerebral atherosclerosis (I67.2)
  • primary pulmonary atherosclerosis (I27.0)

How long has I70.338 existed?

I70.338 has been in ICD-10-CM since at least FY2016, the earliest fiscal year on record here.

Derived from the official order files for FY2016–FY2026. FY2017 and FY2020 publish no order file, so those years are not covered.
